Hi,

I get the following expception when generating the diagram code. I am
using GMF 2.0.2 with Eclipse 3.3.2.

This exception is seen with GMF 2.1.0 with Eclipse 3.4 also.

Exception (Couldn't find operation 'isSuperTypeOf(EClass)' for
EDataType.:in xpt::editor::GenDiagram on line 35
'(EClass)gf.ecoreFeature.eType.isSuperTypeOf(eType)') while generating code

I did read a temporary solution in one of the older threads. Boris
mentioned -

Hi Tarek,

As a quick workaround, I may suggest to add to the GenDiagram.ext file the
following declaration:

private boolean isSuperTypeOf(ecore::EClassifier one, ecore::EClassifier
another) :
false
;

This is not a permanent fix, but could at least let you proceed without
waiting for us to fix this bug.

Sorry for the inconvenience and

Best regards,
Boris

Can someone let me know where I can find the GenDiagram.ext file ?

Thanks,
Sunil.

Hello Sunil,

> This exception is seen with GMF 2.1.0 with Eclipse 3.4 also.
Well, looks like this problem was not fixed yet. Can you please submitt a
bugzilla entry for it?
For now try to apply this workaround. You have to switch "dynamic templates"
on and then create GenDiagram.ext on the proper place (inside <templateDir>/xpt/editor
folder) + put corresponding functiona there.
