Has to be filled with valid data' option can not be changed for custom meta data (version 7 R4, only)

First version affected: 7 R4
Products affected: K4 Server
Platforms affected: All
Bugtracker ID(s): K4-5639
Fixed in: This bug is scheduled with high priority for the next release.

We noticed, that in vjoon K4 version 7 R4 it is not possible to change the option to declare a meta data value as mandatory for a task.
Nevertheless, existing task settings in publications, which were updated to version 7 R4, are preserved and of course respected.


We noticed this issue in the following situations:

1. Open a task configuration in K4 workflow editor and select the Data Usage tab.
2. The option 'Has to be filled with valid data' can be enabled or disabled for every custom meta data entry on the list. Confirming the change with a click on OK closes the dialog. But unfortunately, the change of configuration will not be saved permanently. So if you reopen the Data Usage tab you will notice, that all changes regarding the mentioned option haven't been saved.

This causes the following problems for the user:

Workflow changes affecting the 'Has to be filled with valid data' option are not possible in vjoon K4 version 7 R4.
