[CDO]: CDOViewImpl#getResource on resource that does not exist throws InvalidURIException [message #426178]

Hi all!

I'm writing tests for my Defs when I came across the following:

I execute CDOViewImpl#getResource with a path that denotes a resource
that does not exist yet. The result is that CDOURIUtil throws a

org.eclipse.emf.cdo.util.InvalidURIException: Invalid URI: cdo://repo1/test1

On the other hand, if I use no demandLoad, I get null.

Is this behaviour correct?

the cause I tracked so far is that this happens when the inexisting
resource gets demand loaded. CDOView tries to register a proxy resource
(CDOViewImpl#registerProxyResource(CDOResourceImpl resource)) and fails
when its up to get its resource id (getResourceID(path)).

Cheers
André

André,

Yes, this is currently the expected behaviour for CDO 2.0.
A discussion about this topic with Ed is pending ;-)

Cheers

Hi Eike

I thought so, it matches quite what I read about ResourceFactories in
Eds Book. I wasn't quite sure though if it's correct to let it fail by
throwing an Exception that tells about an invalid URI. Thanks!

Cheers
André
