I just install the SCALA onto my RH ES 6.4, and I can also create the sample applications without any problem.
However, when I try to modify/add the service topology in the datasource, I cannot see any topology entries, just blank at the bottom.
P.S.: the sample app. has come with the topology of Cloud application and etc...
Do I need to install some rpm? I have tried Firefox ESR 17.0.9 or 24, it has got the same issue.
