Errors on creation diagram editor (Eclipse Luna 4.4.1) [message #1513593]

I tried to follow some tutorials like

gmfsamples.tuxfamily.org - gmf_tutorial7

(gmfsamples.tuxfamily.org/wiki/doku.php?id=gmf_tutorial7)

in order to create diagramm editor on Eclipse Luna 4.4.1.

But the last step: "generate diagram editor" was done multiple times with the same errors:

1)Many exceptions were in the dialog, which was open during generation
All of them like Exception (Boolean expected (was: org.eclipse.ocl.ecore.internal.OCLStandardLibraryImpl$1)!:in CodeStyle, line 18) while generating code Boolean expected (was: org.eclipse.ocl.ecore.internal.OCLStandardLibraryImpl$1)!:in CodeStyle, line 18

2)Generated diagram editor plugin was without manifest file and also without dependencies. I manually added dependencies

3) The last type of problems were because not all code was generated, some classes referenced to another which wasn't generated at all: jfb.examples.gmf.school.model.diagram.edit.policies.ClassroomClassroomStudentsCompartmentCanonicalEditPolicy; jfb.examples.gmf.school.model.diagram.part.SchoolVisualIDRegistry; jfb.examples.gmf.school.model.diagram.providers.SchoolElementTypes; jfb.examples.gmf.school.model.diagram.edit.policies.ClassroomItemSemanticEditPolicy; jfb.examples.gmf.school.model.diagram.part.SchoolVisualIDRegistry;

and so on.

I tried to do many GMF tutorials on Eclipse Luna but result was the same.
It looks like GMF couldn't create diagram editor on Luna at all.

Hello there,

Probably the tutorials that you are using are not up to date. Apart from that, it would be a good idea to attach a minimal example of this project that reproduces the error so as for anyone interested to look into it and reply.

Considering that no example is given, I would point out some general tips:

- Put much effort in to the Ecore model, because most of the times the errors are originated from there.
- Take a look into Eugenia Epsilon(Eclipse) in order to get started because starting with GMF, and working through the dashboard might not be an easy task for beginners.
- Follow this tutorial https://www.eclipse.org/epsilon/doc/articles/eugenia-gmf-tutorial/ of EuGenia and then try to create the same in GMF; after you have understood the concept of how the Ecore should be modeled.
