Hi,
I try to generate a .dawngenmodel from an ecore genmodel. But the action leads to a FileNotFoundException. The file not found is the file the action is supposed to generate.
If I look at the dawn code in
GenerateDawnGenModelAction.java:205 it tries to load the resource the following way:
resourceSet.getResource(uri, true);
which looks ok (as far as I understand the code).
ideas?
- Ronald

Not exactly. Dawn currently supports generating extensions for GMF
editors and EMF (tree-based) editors, although the latter is still work
in progress.
To gain the required information the Dawn GenModel decorates the other
generator models. So the Dawn GenModel can hold a reference to the EMF
genmodel (*.genmodel) and/or the GMF genmodel (*.gengmf).
To add the GMF related information the context menu on the *.gmfgen must
be used invoked whereas you must use the context menu entry in the
*genmodel to add the information for the tree-based editor. That's why I
asked what kind of editor extension you tried to generated.
I admit that this handling is not perfect yet. Soon, I am going to
create a wizard which will make the workflow a bit more understandable.
But however. There was indeed a bug in the creation procedure which is
now fixed. It should work with the next build. If not, please let me know.
Cheers,
Martin

I wonder if it's a good design to add dependencies on various third party technologies (GMF, Grafiti, ...) to a single Dawn plugin. Does that mean that a user who only wants to generate a CDO'ified EMF tree editor has to install GMF?

Currently, yes. But the integration of EMF is still in progress and I will use this integration to create a cleaner separation between the runtime/godegen core facilities and the other frameworks.
Cheers,
Martin
