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.
Often, IDE keeps forgetting my project's classes. It is not just an inconvenience but critical bug for the following reasons. 1. Usage Search gives wrong(incomplete) results. 2. Due to above issue, NetBeans ends up breaking the code when we attempt refactoring. Please look into this as this is very critical.
I agree that this is a critical problem, unfortunately it is not clear from the description what is the cause. It is possible that this is a manifestation of issue #128326. Could you please try the binary patch attached to that issue (see comment #21 for installation instructions) to see if it solves the problem? If not, we will need some more info on how to reproduce the problem. Thanks.
I've applied the binary patch and the problem seems* to have gone. However, I'll wait few more days before confirming this. Thanks.
