Description Christian Damus

The AbstractModelerPropertySection refreshes itself in a read-only transaction, assuming that a transactional context is available.  Sometimes, there isn't such a context, as for example when dealing with a proxy object (for which my application wants to show properties).

A fairly simple change to the executeAsReadAction() method will tolerate nulls by assuming that, without a transactional context, the runnable can just be run.

A tweak to avoid the NPE

Attached a patch that fixes the NPE for my scenario and allows the proxy to be displayed in my property section.
