Best practice for skinning a cross-platform action bar in flex mobile

what is the best way for skinning (mxml skin) an action bar with is diffrent in height and icon between andorid and Iphone apps?
can i find somewhere a sample for skinning (spark skin in mxml) an action bar?

I was just dealing with this today on my app, which also has a view with a video object, netstream, netconnection, etc. I was seeing a lot of memory leakage on my device, which then caused the app to crash on the device due to it running out of memory.
here's what I suggest:
-Clean up, close and null all netconnection objects when leaving the view. You should also null all video objects as well. Anything additional that you might have instantiated in actionscript instead of the view mxml.
-The View will take care of discarding its components, any subviews that are present.
If you have FlashBuilder Premium you can use the Flex Profiler to see memory usage of your app when running in the simulator. If you're still seeing problems you can use that tool to diagnose your memory usage

Best Practices for Team Collaboration using Adobe Captivate

With a team of 6 Instructional Designers, how can Adobe Captivate be approached where we can collaborate while producing e-learning material while maintaining a consistent look and feel of the e-learning we produce?
What are the best practices for a team of 6 IDs working and creating e-learning material in Captivate? Is there anything build-in that allows us to connect to the same libraries, templates, etc to share?
Please advise.
Thank you!
Susanne

Only some tips, never collaborated with someone else, being the solo teacher. You didn't mention which version you are using, what I write here is meant for CP7.
Be sure to prepare a theme and/or a template that will be used by everyone. A theme consists of master slides, object styles, skin editor. Master slides can have custom navigation shape buttons. In a template you can eventually also prepare different slides with placeholders, and eventually advanced actions etc. For CP6 and earlier that is the only way to reuse advanced actions, in Captivate 7 you can export shared actions that can be imported in any project for reuse.
A feature that few users know about are the external libraries. You can open the library of any project as an external library in another project. That is a good idea to store assets that you want to use in different projects: images, audio clips, video clips, eventually equations. The shared actions in a library can not (yet?) be used in another project however.
If you are on CP7 you have automatically the roundtripping with source Adobe Photoshop files and source Audition files, both from CC. That can also make collaboration lot easier if those assets are prepared in those applications. Will not expand on that, because I'm not sure you have the Creative Cloud applications.
Those are my two cents.

Best practices for ARM - please help!!!

Hi all,
Can you please help with any pointers / links to documents describing best practices for "who should be creating" the GRC request in below workflow of ARM in GRC 10.0??
Create GRC request -> role approver -> risk manager -> security team
options are : end user / Manager / Functional super users / security team.
End user and manager not possible- we can not train so many people. Functional team is refusing since its a lot of work. Please help me with pointers to any best practices documents.
Thanks!!!!

In this case, I recommend proposing that the department managers create GRC Access Requests. In order for the managers to comprehend the new process, you should create a separate "Role Catalog" that describes what abilities each role enables. This Role Catalog needs to be taught to the department Managers, and they need to fully understand what tcodes and abilities are inside of each role. From your workflow design, it looks like Role Owners should be brought into these workshops.
You might consider a Role Catalog that the manager could filter on and make selections from. For example, an AP manager could select "Accounts Payable" roles, and then choose from a smaller list of AP-related roles. You could map business functions or tasks to specific technical roles. The design flaw here, of course, is the way your technical roles have been designed.
The point being, GRC AC 10 is not business-user friendly, so using an intuitive "Role Catalog" really helps the managers understand which technical roles they should be selecting in GRC ARs. They can use this catalog to spit out a list of technical role names that they can then search for within the GRC Access Request.
At all costs, avoid having end-users create ARs. They usually select the wrong access, and the process then becomes very long and drawn out because the role owners or security stages need to mix and match the access after the fact. You should choose a Requestor who has the highest chance of requesting the correct access. This is usually the user's Manager, but you need to propose this solution in a way that won't scare off the manager - at the end of the day, they do NOT want to take on more work.
If you are using SAP HR, then you can attempt HR Triggers for New User Access Requests, which automatically fill out and submit the GRC AR upon a specific HR action (New Hire, or Termination). I do not recommend going down this path, however. It is very confusing, time consuming, and difficult to integrate properly.
Good luck!

Best Practices For Household IOS's/Apple IDs

Greetings:
I've been searching support for best practices for sharing primarily apps, music and video among multple iOS's/Apple IDs. If there is a specific article please point me to it.
Here is my situation:
We currently have 3 iPads (2-kids, 1-dad) in the household and one iTunes account on a win computer. I previously had all iPads on single Apple ID/credit card and controlled the kids' downloads thru the Apple ID password that I kept secret. As the kids have grown older, I found myself constantly entering my password as the kids increased there interest in music/apps/video. I like this approach because all content was shared...I dislike because I was constantly asked to input password for all downloads.
So, I recently set up an individual account for them with the allowance feature at iTunes that allows them to download content on their own (I set restrictions on their iPads). Now I have 3 Apple IDs under one household.
My questions:
With the 3 Apple IDs, what is the best way to share apps,music, videos among myself and the kids? Is it multiple accounts on the computer and some sort of sharing?
Thanks in advance...

Hi Bonesaw1962,
We've had our staff and students run iOS updates OTA via Settings -> Software Update. In the past, we put a DNS block on Apple's update servers to prevent users from updating iOS (like last fall when iOS 7 was first released). By blocking mesu.apple com, the iPads weren't able to check for or install any iOS software updates. We waited until iOS 7.0.3 was released before we removed the block to mesu.apple.com at which point we told users if they wanted to update to iOS 7 they could do so OTA. We used our MDM to run reports periodically to see how many people updated to iOS 7 and how many stayed on iOS 6. As time went on, just about everyone updated on their own.
If you go this route (depending on the number of devices you have), you may want to take a look at Caching Server 2 to help with the network load https://www.apple.com/osx/server/features/#caching-server . From Apple's website, "When a user on your network downloads new software from Apple, a copy is automatically stored on your server. So the next time other users on your network update or download that same software, they actually access it from inside the network."
I wish there was a way for MDMs to manage iOS updates, but unfortunately Apple hasn't made this feature available to MDM providers. I've given this feedback to our Apple SE, but haven't heard if it is being considered or not. Keeping fingers crossed.
Hope this helps. Let us know what you decide on and keep us posted on the progress. Good luck!!

Basic Strategy / Best Practices for System Monitoring with Solution Manager

I am very new to SAP and the Basis group at my company. I will be working on a project to identify the best practices of System and Service level monitoring using Solution Manager. I have read a good amount about SAP Solution Manager and the concept of monitoring but need to begin mapping out a monitoring strategy.
We currently utilize the RZ20 transaction and basic CCMS monitors such as watching for update errors, availability, short dumps, etc.. What else should be monitored in order to proactively find possible issues. Are there any best practices you all have found when implimenting Monitoring for new solutions added to the SAP landscape.... what are common things we would want to monitor over say ERP, CRM, SRM, etc?
Thanks in advance for any comments or suggestions!

Hi Mike,
Did you try the following link ?
If not, it may be useful to some extent:
http://service.sap.com/bestpractices
---> Cross-Industry Packages ---> Best Practices for Solution Management
You have quite a few documents there - those on BPM may also cover Solution Monitoring aspects.
Best regards,

Best Practices for new iMac

I posted a few days ago re failing HDD on mid-2007 iMac. Long story short, took it into Apple store, Genius worked on it for 45 mins before decreeing it in need of new HDD. After considering the expenses of adding memory, new drive, hardware and installation costs, I got a brand new iMac entry level (21.5" screen,
2.7 GHz Intel Core i5, 8 GB 1600 MHz DDR3 memory, 1TB HDD running Mavericks). Also got a Superdrive. I am not needing to migrate anything from the old iMac.
I was surprised that a physical disc for the OS was not included. So I am looking for any Best Practices for setting up this iMac, specifically in the area of backup and recovery. Do I need to make a boot DVD? Would that be in addition to making a Time Machine full backup (using external G-drive)? I have searched this community and the Help topics on Apple Support and have not found any "checklist" of recommended actions. I realize the value of everyone's time, so any feedback is very appreciated.

OS X has not been officially issued on physical media since OS X 10.6 (arguably 10.7 was issued on some USB drives, but this was a non-standard approach for purchasing and installing it).
To reinstall the OS, your system comes with a recovery partition that can be booted to by holding the Command-R keys immediately after hearing the boot chimes sound. This partition boots to the OS X tools window, where you can select options to restore from backup or reinstall the OS. If you choose the option to reinstall, then the OS installation files will be downloaded from Apple's servers.
If for some reason your entire hard drive is damaged and even the recovery partition is not accessible, then your system supports the ability to use Internet Recovery, which is the same thing except instead of accessing the recovery boot drive from your hard drive, the system will download it as a disk image (again from Apple's servers) and then boot from that image.
Both of these options will require you have broadband internet access, as you will ultimately need to download several gigabytes of installation data to proceed with the reinstallation.
There are some options available for creating your own boot and installation DVD or external hard drive, but for most intents and purposes this is not necessary.
The only "checklist" option I would recommend for anyone with a new Mac system, is to get a 1TB external drive (or a drive that is at least as big as your internal boot drive) and set it up as a Time Machine backup. This will ensure you have a fully restorable backup of your entire system, which you can access via the recovery partition for restoring if needed, or for migrating data to a fresh OS installation.

Networking "best practice" for setting up a farm

Hi all.
We would like to set an OracleVM farm, and I have a question about "best practice" for
configuring the network. Some background:
- The hardware I have is comprised of machines with 4 gig-eth NICs each.
- The storage will be coming primarily from a backend NAS appliance (Netapp, FWIW).
- We have already allocated a separate VLAN for management.
- We would like to have HA capable VMs using OCFS2 (on top of NFS.)
I'm trying to decide between 2 possible configurations. The first would keep physical separation
between the mgt/storage networks and the DomU networks. The second would just trunk
everything together across all 4 NICs, something like:
Config 1:
- eth0 - management/cluster-interconnect
- eth1 - storage
- eth2/eth3 => bond0 - 8021q trunked, bonded interfaces for DomUs
Config 2:
- eth0/1/2/3 => bond0
Do people have experience or recommendation about the best configuration?
I'm attracted to the first option (perhaps naively) because CI/storage would benefit
from dedicated bandwidth and this configuration might also be more secure.
Regards,
Robert.

Option #4 (802.3ad) looks promising, but I don't know if this can be made to work across

Essentially, 802.3ad (also known as LACP or EtherChannel on Cisco devices) requires your switch to be properly configured to allow trunking across the interfaces used for the bond. I know that the high-end Cisco and Juniper switches do support LACP across multiple switches. In the Cisco world, this is called MEC (Multichassis EtherChannel).
If you're using low-end commodity-grade gear, you'll probably need to use active/passive bonds if you want to span switches. Alternatively, you could use one of the balance algorithms for some bandwitch increase. You'd have to run your own testing to determine which algorithm is best suited for your workload.
The Linux Foundation's Net:Bonding article has some great information on bonding in general, particularly on the various bonding methods for high availability:

Best practice for managing a Windows 7 deployment with both 32-bit and 64-bit?

What is the best practice for creating and organizing deployment shares in MDT for a Windows 7 deployment that has mostly 32-bit computers, but a few 64-bit computers as well? Is it better to create a single deployment share for Windows 7 and include both
versions, or is it better to create two separate deployment shares? And what about 32-bit and 64-bit versions of applications?
I'm currently leaning towards creating two separate deployment shares, just so that I don't have to keep typing (x86) and (x64) for every application I import, as well as making it easier when choosing applications in the Lite Touch installation. But I know
each deployment share has the option to create both an x86 and x64 boot image, so that's why I am confused.

Supporting two task sequences is way easier than supporting two shares. Two shares means two boot media, or maintaining a method of directing the user to one or the other. Everything needs to be imported or configured twice. Not to mention doubling storage
space. MDT is designed to have multiple task sequences, why wouldn't you use them?
Supporting multiple task sequences can be a pain, but not bad once you get a system. Supporting app installs intelligently is a large part of that. We have one folder per app install, with a wrapper vbscript that handles OS detection. If there are separate
binaries, they are placed in x86 and x64 subfolders. Everything runs from one folder via the same command, "cscript install.vbs". So, import once, assign once, and forget it. Its the same install package we use for Altiris, and we'll be using a Powershell
version of it when we fully migrate to SCCM.
Others handle x86 and x64 apps separately, and use the MDT app details to select what platform the app is meant for. I've done that, but we have a template for the vbscript wrapper and its a standard process, I believe its easier. YMMV.
Once you get your apps into MDT, create bundles. Core build bundle, core deploy bundle, Laptop deploy bundle, etcetera. Now you don't have to assign twenty apps to both task sequences, just one bundle. When you replace one app in the bundle, all TS'es are
updated automatically. Its kind of the same mentality as active directory. Users, groups and resources = apps, bundles and task sequences.
If you have separate build and deploy shares in your lab, great. If not, separate your apps into build and deploy folders in your lab MDT share. Use a selection profile to upload only your deploy side to production. In fact I separate everything (except
drivers) into Build and deploy folders on my lab server. Don't mix build and deploy, and don't mix Lab/QA and production. I also keep a "Retired" folder. When I replace an app, TS, OS, etcetera, I move it to the retired folder and append "RETIRED - " to the
front of it so I can instantly spot it if it happens to show up somewhere it shouldn't.
To me, the biggest "weakness" of MDT is its flexibility. There's literally a dozen different ways to do everything, and there's no fences to keep you on the path. If you don't create some sort of organization for yourself, its very easy to get lost as things
get complicated. Tossing everything into one giant bucket will have you pulling your hair out.

What is best practice for conditional rendering?

i have a set of radio buttons that conditionally render another set, which in turn conditionally render a 3rd set.
i am doing this by using a valueChangeListener on an h:selectOneRadio
when i click yes on the 1st set it renders the 2nd set.
when i click yes on the 2nd set it renders the 3rd set.
when i click no on the 1st set now it correctly removes the 2nd & 3rd sets, the method also nulls the values.
when i click yes on the 1st set, it renders the 2nd set with the old values even though they were nulled. and i can see in the debugger they are still null.
so there seems to be an issue updating the model, but i dont know what that issue is. im sure it just has something to do with the way i am trying this conditional render. please see below for my first field and my valueChangeListener method.
any help with what is a best practice for this scenario would be greatly appreciated.

               it.remove();
          this.getFacesContext().renderResponse();
     }i also tried doing this another way by just using an action method attached to the a4j:support tag, but that introduced a different set of issue. so ill leave that out for now unless that is the direction someone would like to direct my issue in.
Thanks in advance

Similar issue is covered and explained here: [http://balusc.blogspot.com/2007/10/populate-child-menus.html]. Not sure if it solves your problem as you're using ajax4jsf whereas I don't, but it might give new insights. To the point you might need to bind the component(s) and use setValue(null) or setSubmittedValue(null).

Best practice for mouseless ADF applications

I am developing an ADF application where the users do not want to use the mouse.
So I would like to know if there are a best practice for this?
I am already using the accessKey functionality and subforms defaultCommand
But I have had problems setting focus to objects on a page like tables. I would like a button to return the focus to the table after it has made the command like delete.
I have implemented a solution where I have found inspiration several threads and other webpages (see below).
Is this solution okay?
Are there any problems with it?
I would also like to know if there are better pathways to go like
out of the box solutions,

Hi,
I am developing an ADF application where the users do not want to use the mouse. So I would like to know if there are a best practice for this?
Well HTML (and this is the user interface you see) follows a tab index navigation that you follow with "tab" and "shift+tab". Anything else is a short cut for which you use mnemonics (as you already do) or shortcuts (explained in http://one-size-doesnt-fit-all.blogspot.dk/2010/11/adf-ui-shell-supporting-global-hotkeys.html). There is a distinction to make between non-web environments (which I think you and your users have abackground in) and client desktop environments. Browsers block some keyboard functionality for their own purpose. So you may have to find a list of keys first that work across browsers. Unlike desktop clients, which allow you to "press a button" without the button to take focus, this cannot be done on the web. So you need to be clever here, avoiding buttons at all.
The following paper is about JavaScript in ADF and explains the basics for what Chris Muir explains in : http://one-size-doesnt-fit-all.blogspot.dk/2010/11/adf-ui-shell-supporting-global-hotkeys.html
http://www.oracle.com/technetwork/developer-tools/jdev/1-2011-javascript-302460.pdf
It has the outline for how to register short cut keys that perform a specific action (e.g. register ctrl+d to delete the current row you are on, or press F11 to execute a query (similar to Oracle Forms frmres files)). However, be aware that this includes some code you have to write (actually quite some code to be honest).
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/79-global-template-button-strategy-360139.pdf (are there an example implementation?), or
http://one-size-doesnt-fit-all.blogspot.dk/2010/11/adf-ui-shell-supporting-global-hotkeys.html
Actually these are implementations as they come with example code for you to use and customize, do they? So what is this question asking for more ? Also note that global buttons don't quite have anything in common with the question you asked. I assume you want to see it as an implementation of the Forms toolbar that operates on the form or table the focus is in. This however does not work for the web as there is nothing that keeps track of which component has a focus and to what iterator (data block) it belongs. This would involve even more coding (though possibly doable)

Best practice for Spark repeating background image in a SkinnableContainer?

In my old Flex 3.5 code I would accomplish this by dropping an Image into a Canvas and hitting the Canvas with some css style stuff to get the repeat. The Image tag had a source property that would take a web address so I could dynamically grab different images from the web based on some conditions. Little bit more trouble with Flex 4.5 and Spark but I'm trying to get there.
Here Adobe docs explain how to *embed* a background image:
http://help.adobe.com/en_US/flex/using/WS422719A4-7849-4921-AF39-57FF567B483B.html#WS063B0 491-B7AB-4b00-A39F-E44310BCB0E0
They use a BitmapFill object in the skin.

    <s:Rect id="background" left="3" top="3" right="3" bottom="3" alpha=".25">
        <s:fill>
            <s:BitmapFill source="@Embed(source='../../assets/myImage.jpg')"/>
        </s:fill>
    </s:Rect>
Problem is I need to do this without embedding the image. In my old code I grabbed the image from web (set source property on Image tag to web address). What's the best practice for achieving this with a skinnable container? The BitmapFill object used above won't take a web address for a source.
Thanks in advance.

Use BitmapImage with a fillMode of repeat:
<s:BitmapImage source="http://www.google.com/intl/en_com/images/srpr/logo2w.png" width="100%" height="100%" scaleMode="stretch" fillMode="repeat" />

Best practice for setting or detecting screen size?

Hi All,
Trying to determine a best practice for setting or detecting the screen size. For playbook and iOS, I can set them. But for Android, the number of devices is too large so I'd rather detect. My first choice is to use the stage.stageHeight and stage.stageWidth. This works fine if I set my stage properties with standard meta data:
[SWF(height="320", width="480", frameRate="64", backgroundColor="#010101")]
However, if I use the application descriptor file to set the stage dimentions (as suggested by Christian Cantrell here http://www.adobe.com/devnet/flash/articles/authoring_for_multiple_screen_sizes.html)
<initialWindow>
<aspectRatio>landscape</aspectRatio>
<autoOrients>false</autoOrients>
<width>320</width>
<height>480</height>
<fullScreen>true</fullScreen>
</initialWindow>
Then the stage.stageHeight and stage.stageWidth are not the correct numbers when my main class is added to the stage. Sometime after the main class is added to the stage, then those numbers are fine. Is there an event I can wait for to know that the stage.stageHeight and stage.stageWidth are correct?
Thanks in advance!

Hi Lee,
Thanks for the quick response! However, for some reason the heightPercent & widthPercent metadata tags are not working as expected for me.
I have a wrapper class that I target for compiling, WagErgApplePhone.as where I've got my metadata
[SWF(heightPercent="100%", widthPercent="100%", frameRate="64", backgroundColor="#010101")]
sets some stage properties
stage.quality=StageQuality.LOW;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;
and instantiates my main class
var main:Main = new Main();
addChild(main);
my main class constructor even waits for the stage
public function Main(){
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
in my init function, stage.stageHeight traces out as 375 (expecting 320).
i have a function which is called via a button press event by the user, and stage.stageHeight traces out correctly (320) there. that's what makes me think that if i wait long enough, i can get the correct stageHeight before init/drawing. but i'm not sure what event to listen for, or if there's another trick.
if i use Capabilities.screenResolutionX and Capabilities.screenResolutionY the correct values are provided for mobile, but these values are not useful for the desktop and web version of the app. if there's no other solution, i'll execute different code depending on platform.
again, for reference, my app descriptor:
<initialWindow>
<aspectRatio>landscape</aspectRatio>
<autoOrients>false</autoOrients>
<width>320</width>
<height>480</height>
<content>bin-iOS/WagErgApplePhone.swf</content>
<title>WAG ERG</title>
<fullScreen>true</fullScreen>
<renderMode>cpu</renderMode>
</initialWindow>
looking forward to any other ideas to try out & thanks so much for your thoughts! if you want to really dig in, this is an opensource project at code.google.com/p/wag-erg/

Best practice for OSB to OSB communication

Cross posting this message:
I am currently in a project where we have two OSB that have to communicate. The OSBs are located in different security zones ("internal" and "secure"). All communication on a network level must be initiated from the secure zone to the internal zone. The message flow should be initated from the internal zone to the secure zone. Ideally we should establish a tcp connection from the secure zone to the internal zone, and then use SOAP over HTTP on this pre-established connection. Is this at all possible?
Our best approach now, is to establish a jms-queue in the internal zone and let both OSBs connect to this. All communication between the zone is then done over JMS. This is an approach that would work, but is it the only solution?
Can the t3/t3s protocol be used to achieve our goal? I.e. To have synchronous commincation over a pre-established connection (that is established the in opposite direction of the communication)?
Is there any other approach that might work?
What is considered best practice for sending messages from a OSB to another OSB in a more secure zone?

Hi,
In my experience in a live project, we have used secured communication (https) between internal service bus and DMZ/external service bus.
We also used two way SSL with customers.
The ports were also secured by firewall in between them.

"Best practice" for components calling components on different panels.

I'm very new to Swing. I have been learning from tutorials, but these are always relatively simple interfaces , in which every component and container is initialised and added in the constructor of a main JFrame (extension) object.
I would assume that more complex, real-world examples would have JPanels initialise themselves. For example, I am working on a project in which the JFrame holds multiple JPanels. One of these Panels holds a group of JToggleButtons (grouped in a ButtonGroup). The action event for each button involves calling the repaint method of one of the other Panels.
Obviously, if you initialise everything in the JFrame, you can simply have the ActionListener refer to the other JPanel directly, by making the ActionListener a nested class within the JFrame class. However, I would like the JPanels to initialise their own components, including setting the button actions, by using an extension of class JPanel which includes the ActionListeners as nested classes. Therefore the ActionListener has no direct access to JPanel it needs to repaint.
What, then, is considered "best practice" for allowing these components to interact (not simply in this situation, but more generally)? Should I pass a reference to the JPanel that needs to be repainted to the JPanel that contains the ActionListeners? Should I notify the main JFrame that the Action event has fired, and then have that call "repaint"? Or is there a more common or more correct way of doing this?
Similarly, one of the JPanels needs to use a field belonging to the JFrame that holds it. Should I pass a reference to this object to the JPanel, or should I have the JPanel use "getParent()", or some other method?
I realise there are no concrete answers to this query, but I am wondering whether there are accepted practices for achieving this. My instinct is to simply pass a JPanel reference to the JPanel that needs to call repaint, but I am unsure how extensible this would be, how tightly coupled these classes would become.
Any advice anybody could give me would be much appreciated. Sorry the question is so long-winded. :)

Hello,
nice to get feedback.
I've been looking at a few resources on this issue from my last post. In my application I have been using the Observer and Observable classes to implement the MVC pattern suggested by T.PD.(...)
Two issues (not fatal, but annoying) with this are:
-Observable is a class, not an interface; since most of my Observers already extend JPanel (or some such), I have had to create inner classes.
-If an Observer is observing multiple Observables, it will have to determine which Observer called its update() method (by using reference equality or class comparison or whatever). Again, a very minor issue, but something to keep in mind.I don't deem those issues are minor. The second one in particular, is rather annoying in terms of maintenance ("Err, remind me, which widget is calling this "update()" method?").
In addition to that, the Observable/Observer are legacy non-generified classes, that incurr a loosely-typed approach (the subject and context arguments to the update(Observable subject, Object context) methods give hardly any info in themselves, and they generally have to be cast to provide app-specific information.
Note that the "notification model" from AWT and Swing widgets is not Observer-Observable, but merely EventListener . Although we can only guess what reasons made them develop a specific notification model, I deem this essentially stems from those reasons.
The contrasting appraoches are discussed in this article from Bill Venners: The Event Generator Idiom (http://www.artima.com/designtechniques/eventgenP.html).
N.B.: this article is from a previous-millenary series of "Design Techniques" articles that I found very useful when I learned OO design (GUI or not).
One last nail against the Observer/Observable model: these are general classes that can be used regardless of the context (GUI/non-GUI code), so this makes it easier to forget about Swing threading rules when using them (essentially: is the update method called in the EDT or not).
If anybody has any information on the performance or efficiency of using Observable/ObserverI would be very surprised if this had any performance impact. If it had, that would mean that you have either:
- a lot of widgets that are listening to one another (and then the Mediator pattern is almost a must to structure such entangled dependencies). And even then I don't think there could be any impact below a few thousands widgets.
- expensive or long-running computation in the update methods. That's unrelated to the notification model itself.
- a lot of non-GUI components that use the Observer/Observable to communicate among themselves - all the more risk then, to have a GUI update() called outside the EDT, see remark above.
(or whether there are inbuilt equivalents for Swing components)See discussion above.
As far as your remark 2 goes (if one observer observes more than one subjects, the update() method contains branching logic) : this also occurs with the Event Delegation model indeed: for example, it is quite common that people complain that their actionPerformed() method becomes unwieldy when the same class listens for several JButtons.
The usual advice for this is, use anonymous listeners, each of which handles the event from only one source (and generally very close in code to the definition of that source), and that simply translates the "generic" event notification method into a specific method call of a Controller or Mediator .
Best regards.
J.

Best practice for putting together scenes in a Flash project?

Hi, I'm currently working on a flash project with the following characteristics:
using a PC
2048x1080 pixels
30 fps
One audio file that plays (once) continuously across the whole project
there are actions that relate to the audio, so the timing is important
at least 10 scenes
about 7 minutes long total
current intent is for it to be played in a modern theater as a surprise
What is the best practice for working on this project and then compiling it together?
Do it all in one project file?
Split the work into different project (xfl) files for each scene and then put it together when all the scenes are finalized?
Use one project file but create different "scenes" for each respective scene? I think this is the "classic" way (?).
Make the scenes "movie clips" and then insert them into the timeline with the audio as its own layer?
Other?
I'm currently working on it by having it all in one project file. But I've noticed that there's some lag (or it gets choppy) at certain parts during playback and the SWF history shows 3.1 MB with a yellow triangle with exclamation point symbol. Thanks in advance.

you would only do that if it makes your job easier. generally speaking, it would not.
when trying to sync sound and animation i think most authors find it easiest to use graphic symbols because you can see their animation when scrubbing the main timeline. with movieclips you only see their animation when testing.
however, if you're going to use actionscript to control some of your symbols, those symbols should be movieclips.
