User-defined Collections view gets stuck when trying to enter with RAC agent and nodes (4302361)

The User-defined Collections view works fine with the normal oracle agents and RAC agents without nodes.

When entering using RAC node/s to User-defined Collections, there is a message that "User-defined collections can be created only at the single instance or RAC levels"

When entering User-defined Collections with RAC and nodes, the View becomes stuck on the "Retrieving Agent settings" bar.

Creation of user-defined collections for a RAC database should be executed by selecting the RAC agent itself and not the RAC and its nodes.

This is listed as known issue ODB-3029
