[CDO] CDOBlob datatype [message #1739090] Wed, 27 July 2016 13:34 Go to next message

I am trying to use the datatype CDOBlob.
In project org.eclipse.emf.cdo.tests.model3, there is an example model which uses CDOBlob.

Now, my problem is that the ecore validation flags an error if I set my CDOBlob attribute to non-transient as is done in the test-model:

"The attribute 'MyContainer.blobTest' is not transient so it must have a data type that is serializable"

So what is the right setting for CDOBlob? I tried:

1) Non-Transient: this works, but ecore validation throws ugly errors.
2) Transient: changes are not persistent! (Ecore validation flags no errors though).

Can someone help me with this issue?
Thanks!
Robert

1) is the way to go.

I did not notice this before, but our test model3.ecore doesn't validate successfully, either. I'd like to investigate
that when I'm back from vacation. Please submit a bugzilla to remind me.
