I am using 10.1.3.0.1 and for me there are still grave issues with interface management in the WB.
First of all, I get a NullPointerException when clicking the "add" Button on the interface descriptor's implementor list after having refreshed all classes by selecting the project packages and doing "refresh classes" from the context menu. I have to close and restart the WB in order to be able to continue working.
Then, some attributes which are not common among the implementor classes are detected as common query keys.
Lastly, if I use variable one-to-one relationships and de-select some class indicator values, the de-selected implementor descriptors are displayed as selected after workbench restart again, showing me errors about missing class indicator values for selected descriptors (Error 0055).
