We tried to create a bugfix which is also provided as attachment in this email (patch.diff).<br>
The bugfix resolves the valuetypes also by its repository id so its possible to distinguish between Value1 and Value2.<br>
<br>
Do you see any issues with this bugfix?<br>
<br>
Thank you and best regards,<br>
