This release might introduce a breaking change for consumers that use this service without WIBM UI or using an older version of WIBM UI. So It is best to upgrade to WIBM UI 1.5.0

In this release, the server side service and the UI plugin have been reworked in terms of primitive and custom attribute handling, which should work now in all cases and is a lot more flexible and robust. Please give as feedback in case there are still edge cases that cause trouble.
