[flexcoders] Re: BlazeDS and Remote Objects

[tvikatos]

I suggest you have a look here for a clarification concerning various 
flavors of LC data services (one of which id BlazeDS):
http://gregorywilson.wordpress.com/2008/03/27/livecycle-ds-vs-livecycle-

Now if all you need is a function call/response patterm, amfphp should 
be just fine and much better than simple http services.

[flexcoders] Dynamic DataGrid row height ?

[tvikatos]

Hi all
here's the problem:
I want to use a tree as an itemRenderer within a DataGrid (not the 
advanced one as it causes me other problems). Now I want the grid to 
dynamically adjust the row's height to show all of the tree as the user 
opens/closes nodes. I have tried setting the variableRowHeight=true, 
but to no result: the row height remains unchanged and the tree nodes 
disappear if opened.

Any idea how to do this?
Thanks

Thanks Jason!

[flexcoders] Buttons in text

[tvikatos]

I want to have text, where specific words act like buttons, i.e. when 
clicked dispatch an event. Something like hyperlinks that instead of 
opening up web pages, do whatever I want them to do.

Any idea how to achieve this?

[flexcoders] Re: passing data to an EventListener

[tvikatos]

This is a case where you typically want to create a custom button 
component, say myButton. After you create an instance of myButton you 
pass any info you want it to hold, like the i parameter.
When myButton is clicked it emmits a custom Event (create a subclass of 
flash.event.Event) that holds the i parameter.
You listen for you custom event (not click) and once that is fired you 
pick up the i parameter from your custom Event object, that comes as an 
argument to your listener function.
Or you may want to avoid creating custom Event: listen for Click and 
pick up the i parameter stored within the myButton instance:
event.target.i

I guess there are other ways as well, but I think the ones above are 
the 'cleaner' design-wise.

[flexcoders] ListCollectionView bug?

[tvikatos]

According to documentation in relation to addItemAt method, "If the
list is shorter than the specified index, it will grow to accomodate
the new item."
I've found that not to be the case. If you attempth to add an item at
an index larger that the collection length, Flex will throw an exception.

Is this a known issue?

[flexcoders] Re: Can not load Module using ModuleManager ...

[tvikatos]

Well, the error msg you are getting does not point to crossdomain 
security issues. It does suggest though that the swf you are trying 
to load is not a Flex 2 component based on 
Is that the case?

[flexcoders] Loading module from module

[tvikatos]

Loading a module from a module does not work for me.
A->B->C
When B tries to load C (using ModuleManager) the factory returns null,
although all types seem setup correctly.
However if I do
A->C
and then:
A->B->C
then C is succesfully loaded and instantiated within A and B.

Any suggestions of what might be wrong here?

[flexcoders] Does asdoc work??

[tvikatos]

I decided to play a bit with asdoc to document my project, but I just
can't get the damn thing to work. At some point it started complaining
about not being able to find the cairngorm lib classes. I used the
-library-path option to point to the swc, but still getting errors
with very meaningful descriptions:

Error #1095: XML parser failure: Unterminated attribute.

or 
Error: null

Is this a product we can use or just wasting our time?

[flexcoders] Beware with multiple module instances

[tvikatos]

Make sure you do not request a module load for the 2nd time before the 
1st load is ready. More here:
http://blog.startup.gr/blog/_archives/2007/1/30/2695396.html

Any chance we can see the ModuleManager preventing this kind of problem?

[flexcoders] Interfaces and events

[tvikatos]

I 've been puzzled by the fact that some standard Flex 2 interfaces 
(for example IList) have events associated with them.
Is there a way to enforce an interface implementation emmits an event?
And you do you declare that?

[flexcoders] Re: Problem with module classes instantiation through ModuleManager

[tvikatos]

Anyone expert in modules, has a clue?
Is ModuleManager and the factory you get when loading a module, 
supposed to work with AS-only modules?
We are generally lacking documentation and examples with the 
ModuleManager...

[flexcoders] Problem with module classes instantiation through ModuleManager

[tvikatos]

I have a module that combines mxml and as3. The problem I describe
below happens in either case:
* main module file in AS extending ModuleBase
* main module file in MXML extending mx:Module

When I load the module using ModuleLoader and its 'child' property,
all is good.
When I use ModuleManager and I instantiate a module object through
IModuleInfo.factory.create(), the objects defined as MXML tags within
my module are not instantiated (properties remain null).
Is there something I can do to properly instantiate the module
(something that apparently ModuleLoader does behind the scene)?

Or should I just not use any MXML with modules?
