Using Custom Enumerations in WebDynpro

Good morning,

i need a little hint for the following situation:

i created a entity service using a custom enumeration as an attribute. running this entity service in the CAF- Testtool the entries of the custom enumeration are displayed as expected, but...

i would like to use this custom enumeration inside a webdynpro without using the standard CAF webdynpro patterns, like object browser, object link etc...

when i create a DropDownbyKey and bind the datasource on a context node which has the type of my custom enumeration the following error occured.

How can i bind or access my custom enumeration inside the webdynpro runtime?

I am very grateful (awarding points 😉) for any help.

Thanks Jens
