JHeadstart 10.1.3: selection required error on mandatory dropdown list

Question

Situation:
- JHeadstart 10.1.3 build 059
- One JHeadstart Group containing three item regions
- All items are in the item regions and the regions are stacked (generated as tabs)
- In the first region (tab) a mandatory item generated as a dropdown list, using a dynamic domain
When the page starts, the dropdown list displays the meaning value correctly and the list is populated with the correct values. There is no blank option in the list, which is also correct.
If no changes are made to the list and we navigate to the second tab, an error occurs, displayed at the top of the page: status (which is the field name) - selection required.
Under the status field a red message reads: A value must be entered. Even when we change the field's value to another list entry and navigate to the next tab, the error reappears. The error does not appear when we change the field back to a simple textImput item.
Why does this error occur although the field has a correct value?

Steven,
I do also have this problem. It occurs when the VO contains lookup attributes from another enitity.
In the form I have an table with two stacked tabs as overflow. In the context part I do have 4 dropdownlist. Now when I change one of the lookup items (using a LOV group) and press the save button, the first two dropdownlists become empty and the message 'Selection required' is shown. After entering the values and saving again the other two dropdownlists become empty (no message is shown because those are optional). When I'm only changing other items (non lookup items) the form works fine. At first startup the mandatory dropdownlist do have a NULL-value.
As temporary solution I moved all the dropdownlists to the stacked tabs and that also works fine. When three are moved and one remains in the context part, the problem still occurs.
With kind regards,
