Description Chris Simmons

Build Identifier: M20100211-1343

I'm working on an XText project, which uses an MWE workflow to generate the code.  If I run this once, it causes subsequent refreshes for the entire workspace to sporadically occur for the rest of the session.

I found out that this is responsible by kill -3.

It looks like its caused by the method handleDebugEvents.  I can't tell what the heck this code is supposed to be doing.

This is *extremely* frustrating, it takes a good few minutes to refresh my workspace as it is rather large; plus external source attachments on a network drive are being refreshed which slows things down even more...

Reproducible: Always

Steps to Reproduce:
1. Run a MWE workflow
2. Continue working...

This is 100% reproducible, all kinds of actions seem to trigger it like editing, running tests, etc etc.

I see you use an intermediate milestone. Is it possible to upgrade to the released version of Xtext.
Because it ships with a new MWE implementation which solved this issue. 
But it's a different syntax so some migration effort is involved which is why we should fix this for the old code as well.

IIRC this was solved in M6 or something like that together with the impl of the Mwe2 launcher.

I'm glad to hear its fixed!  We do intend to upgrade to 1.0 and helios fairly soon.
