Dynamic Cube using FWM Dimension Meta data diagram java error

[maxchuie]

Hello all
we are experiencing this error Java.lang.NullPointerException                when selecting a data source connection
http://www-01.ibm.com/support/docview.wss?uid=swg21637243

We do have the JBDC connection established.
I have connected to FWM as a source in dynamic cube
added my dimensions
now trying to add the data table references with no success... i get this error.. has anyone else encountered this?

TIA

Resolved----  I had to go to the Data sources on the Project Explorer section and refresh metadata then i was able to bring in the tables by validating the dimensions but had to create joins
