I'm still fairly new to JIRA. Maybe others on this mailing list are as well, so here's a neat trick that I just discovered...
Sub-tasks for JIRA reports. I recently opened OPENJPA-133 ( https://issues.apache.org/jira/browse/OPENJPA-133). While experimenting with this problem, I found another problem with our processing of callback methods. Instead of just opening a new JIRA report, I saw the option of creating a Sub-task. This turned out to be quite nice. All the fields are similar to a standard JIRA report. But, JIRA automatically links the two Issues together and the navigation between the main task and the sub task is integrated into the Issues. The new sub-task looks like an ordinay issue ( https://issues.apache.org/jira/browse/OPENJPA-137), and will eventually get processed like an ordinary issue. Nice feature. Kevin
