Re: Direclty using parent's compoundpropertymodel not possible ?

[Alex Jacoby <ae...@isr.umich.edu>]

I think we're talking about two different things:  I was talking about  
trying to access the model of a parent component, it sounds like  
you're talking about trying to access the model of a superclass.

In the case I'm talking about, you can't access the inherited model in  
your constructor because your object hasn't been added to the parent  
component yet (it will be added after the constructor runs).   
Therefore you need to wait until onBeforeRender to do initialization  
that depends on inspecting the inherited model.

Hope that helps,
Alex
