Hi,

i tried to build a simple statechart editor, but i keep getting the following error, when in try to generate the gmfgen model:

No Definition top::Descriptor::Inner for FigureDescriptor could be found!

I checked the gmfgraph definition file several times, but i didn't find any unfilled references. I also recreated the gmfmap file, but still no success.

How can i find out where the problem originates from?

Validating gmfgraph and gmfmap files is always successful...

Hi,

It seems you have a problem in your graphical definition (gmfgraph). Did you give names to all figure descriptors inside your figure gallery? If you can post an expanded screenshot of your gmfgraph along with the xml content of your gmfgraph, may be we can help you further.

Hi Thomas,

Your TransitionFigure needs an actually figure inside it (a poly-line connection since this is to be used as a connection).

Hi Thomas,

Can you post your mapping definition as well? (like before)

- Asiri

EDIT: Once you have a gmfmap file, never edit gmfgraph, gmftool files individually, always use the gmfmap editor.

Yes, i know, but i keep getting this error even if i create all of the files using the "Simple Graphical Definition Model", "Simple Tooling Definition Model" and "Guide Mapping Model Creation" Wizards and without any manual changes.

Try removing the poly-line connection from your gmfgraph (revert back to original state) and see if you can reproduce the error. If you can reproduce, that means there is some caching problem in eclipse, otherwise it would be very scary indeed Smile

Hello Asiri,

removing the Polyline Connection resulted again in the error. Adding it didn't work until the next restart of eclipse. So it really looks like a cashing problem.

Thanks a lot for your efforts!!

Thomas

EDIT: This bug is pretty annoying as i end up in restarting eclipse almost after each change Shocked

Ok I don't think this is the normal behaviour (for one I don't face such an issue). Once you make a change within your gmfmap editor, can you refresh (righ-lick menu) and then regenerate gmfgen + code and see if your changes have been propagated into code?

Ah yes it works if i use it that way. Sorry Wink I always used the context menu by right-clicking on the gmfmap file in the package explorer. Maybe that makes a difference.
