When creating a new Java action it is possible to select type parameters to use as an input for objects or lists that doesn’t need to be defined in the Java action itself. I noticed that there is no option to dynamically select a member of that input object / list when creating and using the Java action in the microflow for a type parameter object / list as well as the defined object / list.
When using the Find and Filter List Operations it is possible to select a member of the input list. It would be a very nice feature to have in the Java actions as well.
