[news.eclipse.tools.gef] Re: Custom view and ... ??

[Greg <greg.gigon@xxxxxxxxxx>]

That's the whole problem. You can't have direct reference to a model in 
View. When element in Editor was selected SelectionListener call 
selectionChange() in View object. Then using a IAdaptable (EditPart 
implements IAdaptable) i retrive data from EditPart as an Object of 
IMyProperties. Then I'm passing this object to the Viewer and I have 
this data displeyed in a View.
How to do this other way around, how to set data??

Cheers, Greg
