[flexcoders] Plug-in Based application like Eclipse RCP in Flex/AIR
Hello All, I am java developer I mostly work on Eclipse RCP (Rich Client Platform Application) using SWT. I am not an experienced Flex/AIR developer. I just wanted to create Plug-in based application Like eclipse RCP in Flex/AIR so can anyone guide me does Flex/AIR support Plug-in based applications like Eclipse RCP does support flex/AIR “Extensions points” etc? Or is there any alternative solution in Flex/AIR to create Plug-in based application. Please do help me related to this issue I will be thankful to all of you if you send me some useful links or tutorials. Thanks in Advance. Parkash.

very quickly, *objArrCollModelsVO* seems like an
arraycollection...
are you sure that your for loop removes all references?
if item 0 is removed, item 1 becomes 0, so next time when
you remove 1 you
are in reality removing 2 and so on...
try:
*
for( var** k:int = **model.objArrCollModelsVO.length **; k
= 0 ;k-- ) *

Re: [flexcoders] Objects are not Garbage Collected
Thank you Pual for your reply but my Value Objects don't have any listeners
attached to them and no other variable reference's to them i have double
checked every thing after your reply and i still don't have any clue what is
going on ,my task mangers shows me increase of 2MB whenever my command class
runs , moreover my view object is singleton and forcefully call refresh method
when i add my view to display this refresh method actually dispatches Caringorm

Subject: Re: [flexcoders] Objects are not Garbage Collected
In order to be garbage collected there must not be any references to the
object at all. If you have assigned another variable to the object and not
set that to null, it won't be collected. If you have an event handler
associated with an object, it won't be collected. When nothing at all is
referencing the object it becomes eligible for collection. Sometimes that's
easier said than done.
BTW if you have references to children of the object, they won't be available
for garbage collection until no references to them exist.

If you're not listening for the event directly on the component that will be

will will trigger handlers up the display list from where it was dispatched.
So in your case change your dispatch line to:
dispatchEvent( new MyEvent(), true );

The bubbles property is the second parameter on the Event constructor, so
your MyEvent changes should have done the trick. Sorry about the slip up
there, a lot of times if I'm writing something quick and dirty I would do it
like
displatchEvent(new Event(MY_EVENT,true));
your custom Event class is definitely the best practice as you get the const
for the event name to ensure listener's register for the correct event.

Re: [flexcoders] synchronous events in flex
You mean if i have to display an alert message 'Customer name already exists'
them i have to put this code in result method as follows, Basically this is
Command class which implements IResponder .
public function result( event : Object ) : void
{
// Some processing
Alert.show( 'Name XYZ Already Exists' ) ;
CursorManager.removeBusyCursor();
Application.application.enabled =true ;
}
If you meant this then don't you think it is not good design , now suppose if
instead of Alert message i am going to display inline error message on the view
then i have to access view in my command class to display error message.

Hi

There are no synchronous events.
I am calling an Httpservice on focus out event of text field this service
checks name duplication. I want my application to wait for service to
finish and then do some processing
Supply a result handler for the httpservice and put your code in that. It
will be called asynchronously when the result is ready.
Flex doesn't do waiting, except through event handlers.
