This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
If you push a changeset mentioning an issue number in its summary, the next dev build to have that changeset will produce a note in the issue - great. But if you push multiple changesets mentioning the issue between a pair of dev builds, the notation added to the issue report will mention only of them. There is no easy way to find what the others were (beyond hg log -k $num), even if you knew that there were some.
