Viewstack and custom components...

Hi,
I have a viewstack with an id of say "myViewStack" Code is
below. I then have a function and do this:
appViewStack.selectedChild=home; or whatever...
I guess i am referencing the container sorta like a switch
statement of different views that I can change by using the
selectedChild functionality? That is how I am doing it, and I am
not sure if that is right although it seems to work *so far*
Any help appreciated.
I am getting an error that "globalBar" used more than twice.
This is a common toolbar I want to use and want it to appear in all
views/screens in the app. How can I do this and not have the
redundant code.
Within that I have this code
<mx:Canvas id="home">
<comps:globalToolBar id="globalBar" width="100%" />
</mx:Canvas>
<mx:Canvas id="Issues">
<comps:globalToolBar id="globalBar" width="100%" />
</mx:Canvas>
Thanks

Westside,
Can't tell you for sure whether the
selectedChild code is correct, but I'm using it too, and
haven't had any problems with it yet.
Is there any reason you can't rename the id on the second
page?
E.g:
<mx:Canvas id="home">
<comps:globalToolBar id="
globalBar1" width="100%" />
</mx:Canvas>
<mx:Canvas id="Issues">
<comps:globalToolBar id="
globalBar2" width="100%" />
</mx:Canvas>
I'd confidently say that Flex won't allow you to have two
objects with the same ID. Solely, because you can't access them
both from one name.
Hope that helps.
Oz.

XUL implementations and custom components

I've been looking briefly into the myriad XUL implementations and one of my concerns is the ease of incorporating bespoke JComponent subclasses - and also bespoke Border and LayoutManager classes. And then doing things like implementing and using a custom JPanel subclass whilst being able to specify its contents in XML in the same way as a normal JPanel.
Does anyone have experience with achieving the above in any of these, and how elegant is the solution?
I note that Luxor will handle custom components, as will Ultrid - though the latter (sadly, as it looks rather nice) won't work for me as I need to deploy as an applet. Any others? In particular, SwiXML/AT? That looks interesting although the documentation is relatively sparse...
Thanks

Ah - looks like SwiXML has just what I want with regard to the components.

Bindings and custom components

hi, i have created a component that wraps the TextInput
control, but it does not work well with the Binding mechanism.
here is the code:
<vc:myTextInput text="{str}" y="8" tabIndex="0" x="100"
id="in1"/>
and the binding
<mx:Binding source="in1.text" destination="str"/>
does not update the str field, and if str is initialized to a
certain value it would not show on the component,
can any one tell me what i did wrong / forgot to add ??
cheers,
Jaimon

Michael,
ADF Faces does define a default-render-kit ID for its application. For your custom components, you'll need to register your Renderers both in the Basic HTML RenderKit (the default renderkit in the spec) and in the ADF renderkit (which is, if memory serves, "oracle.adf.core".) Once you've done that, your custom components will work fine in ADF Faces. This is a generic problem in the Faces spec - there's no way to add a renderer in all RenderKits.
I'll get a FAQ item added for this issue.

Please Help with Viewstack and custom component

I'm having trouble trying to embed a component within a
viewstack. I have my main applicaiton main.mxml application and the
calander control from quietly scheming (app.mxml) is the component.
The issue I'm having is how to have the calendar show within my
viewstack canvas. The app.mxml file namespaces below:
<?xml version="1.0" encoding="utf-8"?>
<local:app_code xmlns:local="*" xmlns="
http://www.adobe.com/2006/mxml"
xmlns:qs="qs.controls.*" xmlns:g="qs.graphics.*"
xmlns:qc="qs.containers.*"
creationComplete="load();" xmlns:ns1="qs.containers.*"
xmlns:effects="qs.effects.*" width="100%" height="100%"
layout="absolute">
<Style source="calendar.css" />
<Style source="styles.css" />
<Script source="app_imports.as" />
</local>
My application main.mxml has different namespaces:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="
http://www.adobe.com/2006/mxml"
initialize="showLogin();"
layout="absolute"
horizontalGap="0"
horizontalAlign="center"
cornerRadius="20"
xmlns:controls="com.adobe.ac.controls.*"
>
</application>
If I take the code out of app.mxml and plae it on my
viewstack canvas, I get all types of errors referencing functions
or components in the other namespaces.
Does this make any sense ? I just want to view the calendar
in the viewstack.
Please help

I guess I'm just not understanding the difference betweeen
the <local:app_code> in the app.mxml file and the
<mx:Application> in my main application.
If I run the app.mxml by itself, everything is fine. if I try
to take the code out and past it within the viewstack canvas I get
reference errors. It can't find the objects/functions from the
<local:app_code> namespace.
I guess I'm just confused on how to structure the entire
application.
Thanks all for your responses.

Importing custom components

I just downloaded and installed Update 5 and now I cannot import my custom component.
The new update requires the component packaged as a Component Library File with comlib?? extension. I tried to find any docs on the new packaging scheme but couldnt find any. Can anyone on the creator team please supply the info?
Thanks

The importing components in the help contents has a broken link.
The link is "Creating Custom JavaServer Faces Components for Java Studio Creator:,
http://developers.sun.com/prodtech/javatools/jscreator/reference/techart/JSFcomps_building.html
The link should point to the comlib wiki link. It would be even better if the relevant information on complib and custom components is included directly in the help contents instead of an external url.

Building JSF 1.2 Custom Components with EL and standard components

Hi all,
I have built custom components in jsf 1.1 with great success but i am finding replicating the same functionality in jsf 1.2 very difficult. I have some conditions for my new custom component.
- Using jsf 1.2
- Must use unified EL, i am using a UIComponentELTag
- iam using jsf standard html components from javax.faces.component.html here in particular i wont HtmlCommandLink.
Essentially i am constructing a real time command menu. I have a backing bean from which i get command names and descriptions values. I wont to then in real time construct a table of links (using HtmlCommandLink) - all this work is to be processed by a custom component. Basically the commandLink issues a command in my backing bean, a parameter (param) is passed with the commandLink, this is later picked up in the backing bean method.
I can generate the table, and all the HtmlCommandLinks, i have simply looped throught and encoded each of them.
What i can do: i can see the table and the HtmlCommandLinks, but the links dont perform any action when i press them.
What i want help with:
I want to encode a HtmlCommandLink in my custom component with a param, traditionally i would set the action but this is now deprecated, and i need to use the setActionExpression method. I have tried to do this but the actions are note fired its simply doesnt function.
Note:
In jsf 1.1 I use to loop through all the HtmlCommandLink and peform their processDecodes method within my custom components very own processDecodes. The same in jsf 1.2 doesnt seem to yield any results.
Can someone give be an example or solution to this? I have read articles on the net and they seem to all discuss jsf 1.1 which i have done and it works, but i am using unifed EL and jsf 1.2 now.
Many Thanks,
Kev

How to custom skin PanelTabbed and Popup components in ORACLE ADF?

Hi,
I'm new to this framework. I'm trying to custom skin ORACLE ADF tab and popeup components to match with a design provided by my client. But I'm facing challenges in styling them. Does anybody did this before? Or do we have any sample code on the web to follow. Please Guide.
Thanks,
Srini

Hi.
I think that everyone did it before . Take a look into official doc:
Creating and Managing Skins - 11g Release 1 (11.1.1.7.0)
Selectors for Skinning ADF Faces Components
The last link have the full list of Skin Selectors (CSS properties that you can change) of the ADF Components.
There is also an IDE helpful to create Skin call ADF Skin Editor: Application Development Framework Downloads
I hope it helps.

Upgrading packages from 2005 to 2012 : Custom components and delyavalidation woes

Hey folks
I've two specific cases with upgrading SSIS 2005 to 2012
1st : most annoying
I have a custom transformation written in c# 2005. It references sql server 2005 dlls such as from
Microsoft.SQLServer.DTSRuntimeWrap
Microsoft.SQLServer.ManagedDTS
Microsoft.SqlServer.PipelineHost
Those are stored under
C:\Program Files\Microsoft SQL Server\90\SDK\Assemblies
The requirement is to upgrade the package to 2012 and the code as well. Since 2005 was not installed on new server , I copied the referenced dlls from old server , added them back to C# project and rebuilt the Custom components dlls then added to GAC
When I open the packages , they complain about the version
Error 2
Validation error. : The component metadata for "My_Comonents, clsid {874F7595-FB5F-40FF-96AF-FBFF8250E3EF}" could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
So I thought , I can add the dll to the toolbox and add it again. WHen I try this , I get this error
"Could not load file or assembly Microsoft.SqlServer.PipelineHost ,version = 9.0.242.0"
Now I assume this is because I don't have 2005 components installed.
Before getting things messy , what should be the right approach :
a- Should I just leave the custom components dlls as they are and add them to GAC ? but they will still need 2005 dlls , should I install 2005 client components ?
b- I can not change the code of the c# project to use new SQL 2012 components , it's a lot of work. so what should be right approach here ?
That was the important part
2- Validation
Even for disabled tasks , like data flow task , setting delyavalidate= True still doesn't help against them being validated and raising error. removing them will help but I do not want , any workaround ?
Thanks

Thanks a lot Joost , appreciate the feedback
This is what I thought too.
I came to the blog you mentioned , but I wasn't sure how it should be related to my problem. Now I think I'll need to make the code changes.
Indeed , I see some declarations of *****90
public void CreateExternalMetaDataColumn(IDTSOutput90 output, int outputColumnID)
IDTSOutputColumn90 oColumn = output.OutputColumnCollection.GetObjectByID(outputColumnID);
IDTSExternalMetadataColumn90 eColumn = output.ExternalMetadataColumnCollection.New();
public override DTSValidationStatus Validate() {
IDTSVariables90 variables = null;
public override void SetOutputColumnDataTypeProperties(int outputID, int outputColumnID, Microsoft.SqlServer.Dts.Runtime.Wrapper.DataType dataType, int length, int precision, int scale, int codePage) {
IDTSOutputCollection90 outputColl = this.ComponentMetaData.OutputCollection;
IDTSOutput90 output = outputColl.GetObjectByID(outputID);
IDTSOutputColumnCollection90 columnColl = output.OutputColumnCollection;
IDTSOutputColumn90 column = columnColl.GetObjectByID(outputColumnID);
SO I should use 2012 references and start migrating this code over ? is it as easy as so ?
Thanks

Loading and Unloading components

Hi, I'm creating an application with flex and at the moment
I'm using a component for each page that I want the user to be able
to click through, then changing viewstates on button clicks.
I was wondering, since some of my components have
autorefreshing data how I'd stop them from all running at the same
time...basically as one component is loaded in, unload another one.
Is this what flex does with the viewstates? or does changing the
viewstate away from what it was, and changing it back again not
cause the component to be reloaded?
I guess I'm trying to figure out the most efficient way to
run my app.
Any ideas? I hope my question makes sense. :)

** Update **
I found that I should be using the ViewStack class to
navigate through custom components.

Issue with SSIS Custom Components - 64 bit SQL 2012

Hello All,
Our SSIS packages built on SQL 2008 R2 make use of some custom components. These custom components are installed as part of an MSI. The dll's are copied over to the Windows/assemble [GAC Folder] and also to the Program Files(x86)/SQL Server/110/DTS/* folder.
The installation does not copy the dll's to the 64 bit program files folder.
X:\Program Files\Microsoft SQL Server\110\DTS
These packages are executed via SQL Agent jobs on a 64 bit SQL server and there does not seem be any issue.
Now we are upgrading our servers to SQL 2012 and we have a new installer for the custom components as well. The new custom components use .NET Framework 4.0 and when installed the dll files get copied over to the Ms.NET 32 bit runtime GAC folder and also
to the SQL Server DTS Folder in x86. The upgraded packages work only when we set the runtime mode to 32 bit. The packages successfully executes within the 32 bit dtexec utility, but when we try to run the same package using a 64 bit dtexec utility the
process errors out with a component failed to load message. The package moves data between two SQL Server instances.
The custom components have always been built for 32 bit runtime. I can run a older package through the dtexec utility (from the 64 bit folder in program files) and it does work without any issues. After the upgrade the package will only execute on
a 32 bit utility. can someone help me understand this issue?
Regards, Dinesh

Thank you Arthur.
i think we got the answer as well, as the .NET framework 3.0 installer copied the files over to the C:\windows assembly the dtexec utility [32 bit/64 bit] was able to load the components.
Now with the new installer the files are copied to specific runtime gac folders as Arthur has mentioned. The 64 bit utility does not find the dlls in the GAC whereas the 32 bit version will find them.
Regards, Dinesh

Error while accessing application with custom components

Hi experts,
I have an application (HAP_MAIN_DOCUMENT) of component FPM_OIF_COMPONENT which uses a Webdynpro component with the same name (HAP_MAIN_DOCUMENT). This Webdynpro component (HAP_MAIN_DOCUMENT) uses 2 other components (HAP_DOCUMENT_BODY and HAP_DOCUMENT_HEADER).
For my client requirement, i need to create the custom components by copying from standard components as the UI layout changes are quiet huge and not manageable with the enhancements. To accomodate this i have changed the standard configurations by replacing the standard web dynpro components with the custom ones copied. Apart fomr this there are no changes to the standard.
While trying to access the application, i am getting the error as Null object reference. the details of the error is as below. Please advice.

Spark skins, modules and custom themes: linking issues?

I've read some other threads on this topic that were related to the pre-release versions, but I can't get a complete answer get. I also opened an issue in the bug tracker (https://bugs.adobe.com/jira/browse/SDK-30748), but I'm also posting here, hoping to get some help.
Basically, I have a bunch of skin classes for the standard Spark controls (e.g. s:Button), as well as other skin classes for my custom SkinnableComponent objects. I need to reuse those skins in many projects, so I created a theme: I put in a Flex Library Project all my skin classes, all related graphical assets, and a defaults.css stylesheet that associates each component with its correct skinClass.
Now, in my modular application project, what is the correct method to link this compiled theme SWC? I tried different ways, and found some issue for each one:
In <app>-config.xml, using the <theme> compiler option: this way, modules don't pick up the skinClass correctly (default components use the standard Spark skin, and for custom components I get many skinNotFound errors).. its a pity, I like this method because command-line invocations of MXMLC (build scripts) automatically apply the settings in the config.xml file, while I have to manually keep in sync any additional compiler argument.
In <app>-config.xml, using the <theme> compiler option and add -compiler.isolated-styles=false: seems to work, but not always.. moreover, the option must be put in additional compiler argument, and not in <app>-config.xml, to have effect... I understand that the config.xml file, in a modular application, is only applied to the main application (or that it must replicated with correct name for each module)?
In additional compiler arguments, using the theme+= option.. these arguments should be used also for modules compilation, and this seems the most effective solution at the moment (swf size of compiled modules has slightly increased), but skinNotFound errors still happens sometimes, usually going away after a clean build.. maybe this has something with the incremental build performed by Flash Builder and/or optimization of modules?
Right now, I've tried adding also -keep-all-type-selectors in the compiler arguments to see how it goes...
Is my scenario supported by Flex 4? How should I setup my environment? I read how to create custom themes in the official documentation (http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7f85.html) and a specific help section exists about using styles with modules (http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-799a.html#WSda 78ed3a750d6b8f1b97f82d12508050aa0-8000), but it only cover simple style sheets, no specific information about compiled themes and the suggested linking strategy.
I'm using Flash Builder 4.5.1 and compiling with Flex SDK 4.5.0 (both application and theme), the project use some Halo components (e.g. DateField) but almost all components are Spark, and I use Spark component for <s:Application> and <s:Module>. Modules are optimized for the main application, and are loaded using the ModuleManager.
Thanks in advance for any help.

I'm not sure Spark components will work if the compatibility mode is set to
3.

Generating a clientId for Custom Components

I am creating a custom component that will be made up of smaller form elements and maybe even smaller custom components. Does JSF provide the mechanism for generating the clientId for each of these components and thier sub-components.
What I don't want to do is this:
writer.writeAttribute("name", clientId + "_id" + subComponentCounter++);
...

I got that part. But what if your component has sub-components. Do you just name them whatever you want? I know that you could. But what if they are dynamically generated? And what if your sub-components have sub-components.
So for example:
Custom Control: Shipping Form
|_Custom Control: Name Form
| |_TextBox: First Name
| |_TextBox: Last Name
|_Custom Control: Address Form
|_TextBox: Street
|_TextBox: City
|_TextBox: State
|_TextBox: Postal Code

Viewstack and custom components...
