Hi all
i am trying a little bit with the e4 example SimpleIDE. I can select
different resources in the navigator without any problem. Then i open the
Context Menu View and select one of the items there. If i now try to select
a resource in the navigator i get the following exception:
java.lang.IllegalArgumentException: Variable selection is not modifiable in
the context PerspectiveImpl (simpleide.perspective.default) Context

The problem seams to be in the method SelectionServiceImpl.setSelection:
serviceRoot.getContext().set(IServiceConstants.ACTIVE_SELECT ION,
selection);
What is the difference between using
"context.modify(IServiceConstants.ACTIVE_SELECTION, ...)" and
"setSelection(selection)" on the ESelectionService instance?
Thanks for information

Hi,
It looks like the code in SimpleIDE was not following the best practice
that has been defined through ESelectionService (it was using an old
technic to propagate the selection)
I've fixed the problem now.

Hi,
This looks like something is messing up the IEclipseContext. The
difference between:
IEclipseContext#set() and IEclipseContext#modify() is that the selection
information is stored in the WindowContext. With modify we are search up
the hierarchy until we find the variable-name. IEclipseContext#set()
only sets the value in the current context and doesn't search up in the
hierarchy.
It looks like something is declaring an variable named "selection" in
the perspective context!
