"Can not edit parameter in Read Database in RapidMiner 7"

jackuct1

I drag a Read Database operator in the process view and then try to edit the parameter, but the parameter can not be edited as showing (btw, I already added a database connection in manage database connections):

Not sure how to solve the problem?

I think your panels got messed up, it looks like they're not docked correctly. Can you go to View > Restore Default View
