This is my second attempt to get help on this topic: my previous message
has mysteriouly disappeared from the newsgroup.
I have built a language project (ANT-based) using the instructions given
in http://wiki.eclipse.org/TCS/Language_Project
Everything works fine: the parser for my DSL is correctly generated and I
can use it to inject models. The textual generic editor is usable too.
My problem occurs upon the following scenario:
1. I start editing some text in the generated textual generic editor
2. while the editor pane is open, I close Eclipse, or I switch workspace
3. I reopen Eclipse, or I switch back to the previous workspace
At this time, Eclipse hangs while loading plugin org.eclipse.am3.core
After several minutes, exception stacks are displayed in the console, with
the following error messages :
Package with uri 'http://www.eclipse.org/gmt/tcs/2007/Editor' not found
Package with uri 'http://www.eclipse.org/gmt/tcs/2007/Outline' not found
Finally, Eclipse opens, with my workbench in its previous state.
As I stated above, everything else works fine: it only seems that EMF is
trying to validate the XMI files of the generic editor, but fails to find
the appropriate namespace definitions at the above URIs.
Has anyone experienced the same problems?
Is it possible to disable this validation step?
Regards,
G. Savaton

Hi Guillaume,
Could you please remember to prefix the subject of your TCS-related
posts with [TCS] as I did in this reply? Thanks.

Could you please give us more information about when this happens?
For instance: where does this error orrur? (e.g., with a stack trace, or
by debugging)
Thanks.

Hi Guillaume,
It seems that the AM3 plugin is trying to load Outline and Editor models
as if they were megamodels.
Did you register the TGE/<your-language>-Outline.xmi and
TGE/<your-language>-Editor.xmi models as megamodels (i.e., using context
menu action "Add megamodel")?
If not, then we have to continue looking for the real cause of the problem.
If yes, the solution is to unregister these megamodels. You can simply
edit (with a text editor) the following file, and remove lines that
correspond to elements you want to unregister from the megamodel list:
<workspace> /.metadata/.plugins/org.eclipse.am3.core/am3Registry-Megamod elRegistry.ecore
Note that because the megamodel registry is associated to the workspace,
changing workspace is also a solution.
Please, let us know if it works.
Thanks,
Frédéric Jouault

Good to hear :-).

Right. The new plugin builder calls the megamodel file "megamodel.xmi",
which hopefully helps.
However, the ultimate goal is definitely to have the builder
automatically do megamodel registration.

Hi Guillaume,
Could you please remember to prefix the subject of your TCS-related

Could you please give us more information about when this happens?
For instance: where does this error orrur? (e.g., with a stack trace, or
by debugging)
Thanks.

Well : I was not sure it was a TCS-related problem.
> Could you please give us more information about when this happens?
> For instance: where does this error orrur? (e.g., with a stack trace, or
> by debugging)
I'm not sure I understand what kind of additional information you need.
At least I will try to clarify a few details :
* The problem occurs during Eclipse startup : the splash screen shows
"loading org.eclipse.am3.core" and then freezes for several minutes.
* During this period, two stack traces are displayed in the terminal from
which I launched Eclipse
* Finally, the workbench opens and is fully usable
This problem occurs only if I have left a source file open in the textual
generic editor before leaving Eclipse the previous time.
I hope it is clearer.
Thanks for your help.
Guillaume

Hi Guillaume,
It seems that the AM3 plugin is trying to load Outline and Editor models
as if they were megamodels.
Did you register the TGE/<your-language>-Outline.xmi and
TGE/<your-language>-Editor.xmi models as megamodels (i.e., using context
menu action "Add megamodel")?
If not, then we have to continue looking for the real cause of the problem.
If yes, the solution is to unregister these megamodels. You can simply
edit (with a text editor) the following file, and remove lines that
correspond to elements you want to unregister from the megamodel list:
<workspace> /.metadata/.plugins/org.eclipse.am3.core/am3Registry-Megamod elRegistry.ecore
Note that because the megamodel registry is associated to the workspace,
changing workspace is also a solution.
Please, let us know if it works.
Thanks,
Frédéric Jouault

Yes, I did.

It works.
I remember that when I first tried the editor, I had a message like
"Please register the appropriate megamodel". Since it was not obvious
which file should be registered, I started registering XMI files, starting
from those related with the editor, until the editor was usable.
Thanks a lot,

Hello,

Good to hear :-).

Right. The new plugin builder calls the megamodel file "megamodel.xmi",
which hopefully helps.
However, the ultimate goal is definitely to have the builder
automatically do megamodel registration.
