[mylyn-integrators] Attributes in IRepositoryQuery

["Schenkenfelder Robert" <robert.schenkenfelder@xxxxxxxxxxxxxx>]

Hello,

two quick questions:

- How can I remove attributes after setting them with
IRepositoryQuery.setAttribute()? I haven't found any remove or drop or
clear method, only getters and setters.

- After editing the properties of a query, the tasks which should be
displayed in the task list may have changed. The tasks with the new
query properties are correctly shown, but after the next start of
Eclipse the old tasks are in a new category "unmatched". How can I drop
this old tasks and/or prevent Mylyn to move them to unmatched?

Thanks,
Robert
