Hi! There are many properties in the gmfgen that I would to preserve when
I regenerate the gmfgen from the gmfmap (for example, the Node Visual ID).
Are there any way to do this in the gmfgen file?

Thanks.
Marc.

Hello Marc,

Modified .gmfgen property values should be preserved by "reconciler" sybsystem.
Concerning node visual ID property: try using org.eclipse.gmf.bridge.trace
plugin - it was designed to preserve visual id of the corresponding .gmfgen
model elements on next map -> gen transformations.

Hi Alex, thanks for your reply.

I have downloaded the 'GMF-sdk-experimental-2.0.2' and add all the plugins
to my eclipse directory. Then, I have regenered the gen, and all the ID's
have incremented 1000 units. For example, a node with an ID 2015, now has
3015.

Is there any documentation about this plugin? Or can I configurate it?

Thanks a lot.
Marc.

Hello Marc,

I'm not sure about the documentation.
This plugin will create .trace file opn first execution and then use visual
ID values stored in this file.
So, first time all the visual IDs in your model will be changed, but then
you can manually patch .trace file to return old values back.

Hello Alex,

I have generated the gen file, but I realize that the entry 'Gen Diagram'
that represents the canvas element doesn't appears in the .trace file, so
it always changes this Visual ID if I modify it (always changes the value
to 1000).
It's a bug, or it's the expected behavior?

Thanks. Marc.

Hello Marc,

Yes, looks like diagram visual ID was not included into the trace.. Can you
as a solution for now try to migrate completely to the new visual IDs?

Hello Alex,

I don't really understand your question. I can migrate all the new visual
IDs, and when I regenerate the gen it preserves all the IDs. But the
solution I found to preserve the diagram visual ID is to change it
manually.
Nowadays it's the only one way to preserve this ID, isn't it?

Thanks. Marc.
