When I define an adapter factory extension and the adapter type is a member interface (i.e. it is an interface defined inside another type) and the XML element looks like this: <extension point="org.eclipse.core.runtime.adapters"> <factory class="org.eclipse.jpt.jpa.core.internal.ProjectAdapterFactory" adaptableType="org.eclipse.core.resources.IProject"> <adapter type="org.eclipse.jpt.jpa.core.JpaProject.Reference"/> </factory> </extension> There are no warnings or errors; but the factory will not be invoked because the adapter type name is incorrect. I would expect a warning like the following: Referenced class 'org.eclipse.jpt.jpa.core.JpaFile.Reference' in attribute 'type' is not on the plug-in classpath The adapter type name must be changed to look like this: <adapter type="org.eclipse.jpt.jpa.core.JpaProject$Reference"/> Note the member type must be separated from the top-level type with a '$'.
Related to this bug: When editing a plugin.xml file, if the cursor is positioned on the name of a member type and I press F3, the UI will only open an editor on the member type if its name is "incorrectly" entered. That is, F3 only works if the type name uses a '.' separator, as opposed to the '$' separator; but, as mentioned in the original bug description, the '.' separator does not work at runtime so it's pretty much useless.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
