yes, syntax is wrong... :)
Marcel, could you please provide the a complete file as a repro? Which proposal did you select?
Created attachment 210537 [details] Example Attached simple test scenario that causes the exception in my setup. Trigger position is $. Selected: java.lang.String Installed version: Xtend2 SDK 2.3.0.v201201310353
I could not reproduce this on the current HEAD. I suppose the fix came with cb811286a096cea2ade126172fffc33bee0248e6.
Just stumbled accross this one
Turned out that the problem was caused by a recent refactoring. see bug 369411
Closing all bugs that were set to RESOLVED before Neon.0
