Daniel Azarov commented on JBIDE-11185:
---------------------------------------
I reproduced it again.
Test case
Execute:
1. Created 5 seam projects with different Seam Runtimes, for instance, I have:
- jboss-seam-1.2.1.GA
- jboss-seam-2.1.1.GA
- jboss-seam-2.2.1.CR1
- jboss-seam-2.3.0.ALPHA-distribution
2. Close Studio
3. Start Studio
4. Just after starting Open Window->Preferences then select JBoss Tools->Web->Seam
5. Delete all Seam Runtimes one by one
FAIL:
