Description Stephen Williams

Build Identifier: 20100917-0705

I am adding a new feature to an application in the context of a Mylyn task and have just noticed that Eclipse has removed a Java source file I created this morning from the task context. The source file editor was still open, though, and, when I clicked on the editor tab, the source file reappeared in the Package Explorer.

Can you please confirm whether this behaviour is by design or is a bug? Specifically, will the automated context management ever remove source files from a task context that were created while the task context was active?

I recently posted a question on the Eclipse Community Forum asking for information on the automated context management implemented by Mylyn but, unfortunately, nobody replied to my post.

Reproducible: Always

Hi Steffen

I've read through the other bug report and I am not completely clear on whether or not Mylyn is behaving as I would expect it to behave.

To restate my question as simply as possible, files created / modified as part of a task do seem to be subject to decay and eventual removal from the task context - is this a bug or by design?

If it is by design, that is a problem as, if I add a new file or modify an existing file while a task is active, that file will always be relevant to that task and should never be automatically removed.

Regards

Stephen

Yes, this is by design. Files do not actually get removed but the are filtered from focused views when their interest level falls below a certain threshold.

Elements that are modified get a higher interest level than elements that are selected only so it takes much longer for their interest to decay below the threshold. Still, when working on a task for a long time you may end up editing many files and focused views would become overloaded without decay. Also see bug 178891 for a related discussion.

It would be helpful if you added your statements to bug 341631 so they doesn't get lost.
