[CDO] Resource renaming [message #1709290]

Hello,

I encounter the following problem in CDO 4.4 (but not in 4.3):

1) open CDOView
2) open CDOTransaction

- Create CDOResource "home/Administrator/test/a"
- Rename resource from a->b
- Create CDOResource "home/Administrator/test/a"

If, from the view, I access the nodes for CDOResourceFolder "home/Administrator/test" via getNodes(), I get an IllegalArgumentException as is shown in the stack trace. I guess this is an additional safety mechanism for CDO4.4? How can I access the nodes of the folder after this?

Caused by: java.lang.IllegalArgumentException: The revision CDOResource@OID928:0v1("a") does not match the object OID876

Hi Robert,

I'm about to leave into a one week vacation. In the meantime you could try a newer (today's) 4.4 maintenance build. If
it still doesn't work please submit a bugzilla...

Cheers
