[flexcoders] Re: unable to bind to property 'width' on class 'Object'

2008-11-06 Thread Juan Carlos M. 
I had to rewrite my mxml component as an actionscript component...
although there are some warning: unable to bind to property 'width'
on class 'Object' (class is not an IEventDispatcher) the component is
shown on the screen...

but there is a new issue...
this piece of code that worked in the mxml version:
_legendWindow = ThemesControl(
PopUpManager.createPopUp(this,ThemesControl, false));


now throws the following error:
TypeError: Error #1009: No se puede acceder a una propiedad o a un
método de una referencia a un objeto nulo.
at _ThemesControlWatcherSetupUtil/setup()
at ThemesControl/initialize()[ThemesControl.mxml:0]

   You can get ride of it by typecasting your Object into an XML
like this:

I´ve extended a Canvas component using mxml. When I use that

That probably means that some child object isn't created yet, although Binding 
usually ignores such errors.  Might you be calling initialize() out of order?

There is a recipe for creating components that we recommend you follow.  It 
is written up in the documentation, but also recently in Flex Authority 
Magazine.

As far as binding warning are concerned, sometimes they can be ignored, and 
sometimes not.  The warning is there for a reason.  It is unusual for an MXML 
component that subclasses a display component to not be an IEventDispatcher, so 
there is something odd about that situation as well.Can you give us an idea 
of what the MXML version looked like?

2008-11-06 Thread Juan Carlos M. 
finally it worked using  BindingUtils.bindProperty and rewriting some
code related to [Bindable] get/set methods. 

It seems that the main error its due to this kind of binding:

text={iMap.map.selectedLayer.label} 

In that case databinding is not handling gracefully the case when iMap
is null.  Such kind of error causes a total break of the app.
