TCS language project : Eclipse hangs when opening workspace [message #608251] Mon, 12 November 2007 16:26

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
