Hi,
I'm having problems writting PDE Junit test for my application and I need
some help/advice.
What the application does is to register for java model events and based
on these events to update an EMF model.
The testing strategy is to do a change and then in the same trhead check
whether the model has been updated.
This ussaly works as the event broadcast is done in the thread performing
the java model change. However in some very rare cases the event is
delivered in a different thread. Can you point me why sometimes the Java
Model Event gets delivered by a different thread. Bellow I'm providing the
stack-traces of 1. Normal event delivery i.e. the change and event happens
in one and the same thread, 2. Stack traces of the thread doing the change
and a stack trace of the thread delivering the event. The event itself is
about an oppened project and looks like:
org.eclipse.jdt.core.ElementChangedEvent[source=Java Model[*]: {CHILDREN |
CONTENT}
TestEJBProject3_1185799757714 11[*]: {OPENED}
ResourceDelta(/TestEJBProject3_1185799757714 11)[*]]
The validation code executed by the job comes from WTP. I.e. the class
ValidationOperation is of package
org.eclipse.wst.validation.internal.operations
Thanks,
Hristo
