Hello,

I have several files of a custom content type residing within a project.
The project-relative path to one of these files is stored as a
persistentProperty on the project.
I also have a PropertyPage and several command handlers that are enabled
when the user selects a project. I'd also like to have these enabled
when the file whose name was stored on the project is selected.

Is there a way to achieve this declaratively? So far I found no mention
on how to compare two such values in the plugin.xml.

Regards,
Damian

There is a property tester for project persistent properties,
org.eclipse.core.resources.projectPersistentProperty. But it can check
for a constant value, not parameterized or work with the current selection.

You would probably have to write your own property tester that looked up
the IResource's projectPersistentProperty and compared it to the
IResource name.
