[CDO/XText int [message #989287] Wed, 05 December 2012 09:36 Go to next message
Eclipse User
Hi Xtext community,

I use a XtextResourceSet with cdo URI on Eclipse Juno (4.2.1), on first
call to XtextResourceSet.getResource("cdo://repo1/Test/test.ecore",
true) it returns a CDOResource with a id equals to oid1 (temporary CDOID
to indicate that it is a CDOResource not yet commited to the server), in
the XtextResourceSet.getResource(URI,boolean) the code does not update
the uriResourceMap like does ResourceSetImpl.getResource(URI,boolean) at
the end. Consequently at the second call to
XtextResourceSet.getResource("cdo://repo1/Test/test.ecore", true) the
previously created CDOResource is not retreived from the uriResourceMap
then a new CDOResource is created for the same URI. Then on
CDOResource.save() (i.e. CDOTransaction.commit()) many exception occurs
because CDO complains about 2 CDOResources with the same URI. It seems a
bug in XtextResourceSet which does not update uriResourceMap. What do
you think about that?

Best Regards

I see also that in case of ResourceSetImpl the uriResourceMap by default
is not initialized, equals to null, while in XtextResource it is
initialized with a empty map in constructor.

Please file a ticket against Xtext.
