Flex mxml components should be private by default

Flex mxml components should be private by default. Does adobe
plan to fix this in future versions?

Just noticed this and I think he may have a valid point here.
But as well as reducing coupling the term I'd use to make this
argument is
encapsulation.
There's no way AFAIK to make MXML sub components invisible to
higher level components. This can sometimes reveal things
internally that you don't want messed with, within a custom
component. If you have a custom component that only requires
one property be set to configure it properly, you don't want
to be revealing all these extra sub-components just because they
had to have ids assigned to them inside the custom component.
This may be a headache for backwards compatibility, for
anyone who has assumed these components would be public by default,
but a simple "scope='public'" attribute should fix that. But even
having them public by default, and allowing us to set their scope
to private would be helpful at times.

Resource Module Help for localization in custom mxml components

HI again,
Ok I have my resource set up to load at run time, working
great.
But I have mxml components should they not use the same
loaded bundle, or should I make smaller component bundles and load
them as well.
Best Practice etc...
Thanks in advance.

If you want the components to be decoupled and reusable with
ease, I vote for separate bundles.

Converting MXML Components to ActionScript Classes

I'm in the process of converting most (if not all) of my MXML
components to Action Script classes. I've found this is easy, and
doesn't require a lot of extra code when extending a simple
container or control. However, several of my MXML components have
several nested containers and controls - i.e. a component that
contains several Labels, a ComboBox, a TextInput, a Button, and a
DataGrid, plus several other containers needed for layout. To code
the layout of all these containers and controls using MXML, it uses
about 16 lines of code. To code the layout in ActionScript, it
takes about 50+ lines of code (see attached).
I'm just wondering if there are any best practices for
creating ActionScript classes that include several (or even A LOT
OF) containers and controls. It's very easy to layout in MXML, and
is more visibly pleasing to look at and understand, but I feel it
is best practice to code components as ActionScript classes. I know
I should be using MVC, but it's a little late to rewrite the entire
application now.
Any thoughts?

I can't specifically speak to how to write layout code in
ActionScript, but you can look at the generated code that Flex
creates to get an idea of how Flex does it. When you compile an
app, the Flex compiler takes your MXML input and converts it to
ActionScript classes before compiling the entire set of classes
into a SWF. Because of this, you can look at the interim
ActionScript code.
You do this by setting the keep-generated-actionscript
compiler option to true and looking in the /generated directory.

What are you supposed to cast it to? I might have tried to cast it to something wrong.
I tried
TableCellRenderer tcr = table.getDefaultRenderer(Boolean.class);
((DefaultTableCellRenderer)tcr).setHorizontalAlignment(SwingConstants.LEFT);and that gave me a ClassCastException. But I might have been trying to cast it to the wrong thing.

Architecting an Application With MXML Components

I have an application that has gotten lengthy and I want to
simplify it by architecting the Main Application with custom MXML
Components. The application as it is currently architected works
perfectly.
Currently, the application consists of "Canvas" containers
along Top and Left Side holding Navigation Buttons. The main
(changing) sections of the application will consist of a
"ViewStack" container holding a number of "Canvas" containers
stacked on top of one another. The navigation buttons along the top
and left side, when clicked, display in turn the content of each of
the several stacked "Canvas" containers. Because of the number of
stacked "Canvas" containers within the "ViewStack" and the content
of each, the main Application source code has become very long and
unwieldy, thus the need to use custom components for each of the
"Canvas" containers in the "Stack" and referencing them in the main
Application page.
I have tried several times to get this to work and I need to
clarify a couple of things.
1) After setting up custom components for the several
"Canvas" containers that are now in the "ViewStack" container, do I
first need to set up a custom component for the "ViewStack"
container with its own name space?
2) If the answer to 1) above is Yes then do I then reference
each of the custom components for the "Canvas" container with their
own name space designation within the "ViewStack" reference within
the main Application?
In the event I am completely off base then I would appreciate
any suggestions. If you wish I would be happy to email you the
current application page.
Thanks,
Joe

Using salesforce connector in multiple mxml components

I am using Flex 2.0.1 and Salesforce as Database. My question
is i am creating login method in each component and application. I
want to use/pass salesforce connection from main application to all
sub component, how can i achieve this to avoid login for each
application/ component.
example: In my project i created main.mxml application and 3
mxml components in each component i am logining into the salesforce
database to retrieve data from the database. i want to avoid
creating multiple logins for the components instead of writing
login for each mxml component i want login for the first time in
main.mxml application and want to use the same connection in mxml
components. Can anyone tell me how can i achieve this
If you feel this is not sufficient information to solve this
problem then let me know i will post another message with sample
code.
Thanks in advance.

The solution I ended up using was just to reference the CSS file at the root MXML application. Then I could just use .styleName on the Menu component and voila, it worked.

Anyway to make MXML components static?

This isn't too important because I know how to do it well enough in ActionScript. But I like the readability and convenience of MXML components, so if anyone knows if there is a way to make them static, please let me know.

As best I understand it, there is no way to creation Static Classes in ActionScript 3 or MXML:
Class Modifier keywords are dynamic, final, internal, and public.
http://livedocs.adobe.com/flex/3/html/help.html?content=04_OO_Programming_06.html
The Static keyword is only for variables, constants, or methods:
http://livedocs.adobe.com/flex/3/langref/statements.html#static
If you want to create static variables, constants, or methods inside an MXML File do it in a script block, which is the same way you do it in an ActionScript 3 file.

Mxml components not compiled into swc?

Hi, I am using Flash Builder(Flex 4) and i am having issues compiling mxml components into swc.
My scenario:
I created Flex Library project, added some mxml components and actionsript classes.
I created separate Flex project and added swc file to project's library path.
I can only import actionscript classes from my library.
ActionScript classes are compiled and bundled in the swc as expected, but all mxml components are not compiled into the swc.
Do you have the same issues compiling mxml components?
I am using Flash Builder Version 4.0 (build 253292).

My team occasionally sees issues with missing classes in a similar setup, although I can't confirm that it has been limited to MXML (and no one has been able to reliably reproduce).
I suspect our problem is the "includeAllClasses" property in .flexLibProperties (Project->Properties->Flex Library Build Path->Classes->Include all classes from all source paths)--it seems to not reliably compile in newly added classes. Our workaround right now is to instead click "Select classes to include in the library" and toggle our source directory every time classes are added, at least until we script our own build tasks. Looking through Jira I see this is a common issue: https://bugs.adobe.com/jira/browse/FB-23514 (and a few others).
Hope this helps,

Dynamically add custom MXML components in Actionscript

As there's no constructor for custom MXML components, how to
dynamically add it as a child using ActionScript?
I'm looking for some alternative to avoid the need to rewrite
the entire existent component in ActionScript just to add it this
feature (a constructor). PopManager is not an alternative...
Is there any way?
The case/situation:
I have a custom MXML component that needs to be dinamically
added to a NativeWindow created using ActionScript.
Thanks a lot!

mxml classes get generated into AS classes with a default
constructor.
In fact, there is essentially no difference between an AS
component and an mxml component, they can be used exactly the same
way.

Data between mxml components

I have a question about data between mxml components.
Product.mxml is the overview screen for the products and ProductDetail.mxml (it is a TitleWindow) the detail screen.
In the Product I define a value object ProductVo with all the data. When I click a record in the overview and click the button 'change' (changeProduct function) then a popup window appears with all the data in it.
Code in Product.mxml:
[Bindable]
public var myWin:ProductDatail;
private function changeProduct():void {
myWin = PopUpManager.createPopUp(this, ProductDetail, true) as ProductDetail;
myWin["btnSave"].addEventListener("click", save);
private function save(event:Event):void {
productVo.productId = myWin.ti_productnr.text;
productVo.name = myWin.ti_name.text;
productVo.ean = myWin.ti_ean.text;
...some code to save the data in the db...
Code in ProductDetail.mxml:
[Bindable]
public var productDetailVo:ProductVo;
    <mx:Form>
        <mx:FormItem label="Productnr" required="true">
            <mx:TextInput id="ti_productnr" text="{productDetailVo.productId}" width="60"/>
        </mx:FormItem>
        <mx:FormItem label="Naam" required="true">
            <mx:TextInput id="ti_name" text="{productDetailVo.name}" width="200"/>
        </mx:FormItem>
        <mx:FormItem label="Ean">
            <mx:TextInput id="ti_ean" text="{productDetailVo.ean}" width="100"/>
        </mx:FormItem>
        <mx:FormItem direction="horizontal">
            <mx:Button id="btnSave" label="Save"/>
        </mx:FormItem>
    </mx:Form>
So my question: the save function in Product.mxml, is it possible to do this in a easier way instead of linking all the data from the form into the value object? Something like productVo = myWin.productDetailVo, but that does not work.

I just looked at the parsley framework and saw this code:
private function save():void
contact.firstName = firstName.text;
contact.lastName = lastName.text;
contact.email = email.text;
service.save(contact);
So, it is doing the same thing I'm doing.
I'm using Spring and hibernate on the server level, it is my own framework.

FREE check box in PO should be selected by default for specific material

Hi All,
We have a check box FREE in PO creation - ME21N in the item row which is selected when ever we want the vendor to supply those items as free.
- I have a list ot items which are supplied freely by the vendor which I have to mention in the PO. My requirment is when ever the specific material is in the PO the FREE check box should be selected by default. Is it possible?
Please advice.
Thanks ,
Vengal Rao.

Hi Vengal Rao,
I don't think there's such flag in the material master. As far as I know any material can be supplied either free or chargeable - the buyer has to choose the applicable option it in each specific PO.
If however in your business case certain materials shall always be supplied as free, then you can use the BAdI that I mentioned above to analyse which material is being procured and set the FREE flag in the PO accordingly.

Where should i put the DEFAULT&SMARTBAR

Hello,
where should i put the DEFAULT&SMARTBAR ? and the main Menu ?
in order to be shown in each form..
in using Forms 6i.
Regards,
Abdetu..

Hello Gerd,
Thanks for reply..
put such things into *a reference form* what is meant by a reference form do u mean the main form?
Create a property class (PC) for your FORM-MODULE-properties,
put this PC into the reference form.
Create there an object group (OG), put the PC into the OG and the inherit the OG to your local form.
Automatically you have then the PC inherited too.i did all what u mentioned..
Bbut the problem is that the DEFAULT&SMARTBAR
can't be seen in allllllllllll my forms in the main menu inspite of i put it into the form module property ->in the intial menu property.

If I create an security scope for a group of SCCM-admins should i remove the "Default Scope"?

Hi,
If I create an security scope for a group of SCCM-admins should i remove the "Default Scope”?
/PS
/SaiTech

Yes, it's OK to not add the Default security scope to an administrative user. You can add any custom security scope to an administrative user and it does
not has to include the Default
security scope.
Just keep in mind that you keep at least an administrative user that contains the
All and/or the Default security scope to not lock yourself out of the console.
