[CDO] generating dawn genmodel [message #638791]

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?

Hi Ronald,

could you provide the complete stack trace? This could make it easier to
judge what happens. ;)

But one question in advance:

Are you trying the generate the extension for a tree-based EMF editor or
for a GMF editor?

Cheers,

Martin

Hi Martin,

below the stacktrace.

I'm not really sure if I understand your question on what I'm trying to generate. I simply right click on a genmodel to generate the corresponding dawngemodel. So, I suppose that can only generate a dawn genmodel for editor support. Later, we'll need a CDO enabled GMF editor or a CDO enabled Graphiti editor.

But first I just wanted to see what code is generated and how I need to change my existing code to make use of the generated dawn code.
First things first Smile

Thanks,

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
