Product Version: NetBeans IDE Dev (Build 200802140010) Java: 1.6.0_03; Java HotSpot(TM) Client VM 1.6.0_03-b05 System: Windows XP version 5.1 running on x86; Cp1251; ru_RU (nb) 1. Start IDE. 2. Remove one of the existing connections. It is removed. 3. Rightclick another connection and choose "Delete". Result: Confirmation dialog appears, but after pressing "Yes" connection is not removed.
I successfully created and deleted multiple connections multiple times without getting this error, including with a clean userdir. I am wondering if your userdir got into a bad state? I am closing with WORKSFORME - please let me know if you see this again...
Fixed.
Verified with build 080215.
