Data Browser copy and paste drop down values

Hello Community,

we upgraded our Oracle Connector and Geospatial Administrator recently (cause of upgrade Oracle 11g to 12c) and I did a re-Register of my Features in Geospatial Administrator.

Afterwards I saw that the Definition of my Domain attributes (Drop-Down-Lists) changed from type string to double (according to database type definitions). In prior releases it was string in my Map Workspace but numeric in database.

Now we are not able to copy and paste these attributes in Bentley Map Data Browser anymore. I select one data row, copy and I'd like to paste to other rows in the browser.

For string-typed attributes it is still working fine.

Are there any options I didn't find yet?

We're using Microstation SS4, Bentley Map SS4, ProjectWise & Oracle Connector CONNECT.

Thanks in advance,

Kind regards,

Maik
