Thanks scabanovich! I'm surprised at your quick response and clear explanation. my team heavily use struts flow editor. I owe you very much, thank you! I want to contribute to development as much as posible, I'm very new to jboss community, so would you tell me some manner at the community? 1. When finding problem which is better ? a. reporting to "develper forum" b. creating issue on JIRA. 2. Is there any good develor tutorial for develper who want to send patch or participating develpment process. I'm also interested where most core jboss developer gathers, e.g mailing list or forums. 3. Should I do something agains bug which I reported? Will this bug be fixed by someone and when? I'm not sure I can fix this bug quickly so I want to know how reported bug are treated in general.
