UML Designer SDK 7.1.0.201611211357 Eclipse Oxygen 4.7.0 Missing Representation Types
Empty representation types selection window using these (both most actual) versions. Workaround with migration to UML Designer 4.0 is functioning in the first step but causing error messages when creating a model package hierarchy denying me any further actions ...
Is there another workaround or is there something to add to my configuration to make it run?
Try to install the nightly version which is a beta version of the 8.0. There is version incompatibility due to Guava between UML designer 7.1 and Eclipse Oxygen. This is fixed in the 8.0 version which will be released at the end of the month.
