[news.eclipse.modeling.gmf] Re: Exception when generating diagram code from .gmfgen
Alex Shatalin a Ãcrit : 
Hello Olivier,

unfortunatly, I got the same exception error with this modification
in my xpt file :(
I have to read it more carefully. :-) I thought exception was thrown by xpand editor.. Sorry.

ÂDEFINE throwIncorrectInputException FOR gmfgen::GenDiagram-Â
If you posted here whole content of aspects/xpt/editor/DocumentProvider.xpt (xutom template) I do not see the reason for this template at all - it is just copying original template contents..
I suggest you to remove "DEFINE uriEditorInputClassFQName", "DEFINE fileEditorInputClassFQName" and call it using fully-qualified names like:
ÂEXPAND xpt::editor::DocumentProvider::uriEditorInputClassFQName ....

Hi,

I paste here the DocumentProvider.xpt

If I understood you correctly, this template do nothing at all. It juste copy things ? I'll try to modify things as you said but I didn't know the xpt usage.

Goodbye,
