I have a dropdown with task types. If is select the task type "restock", it wil bind the following values to the data variable NewTask.

The problem I am facing is that my web page becomes unresponsive as soon as I select Restock:

It happens in every browser. When I remove al dynamic bindings and leave only the static values (1 for pieces and PAK for unit), it works perfectly. But then it will clear all previously selected or filled in values.
Obviously I could make a workaround by enabling certain widgets and assigning the values statically to force a certain flow of use, but that beats the whole purpose of binding dynamic values.
I am also aware this is an issue that is more suitable for a technical ticket, but SAP support told me I am not able to file one with my account type (which is still unclear and a real shame for both parties). Instead, they told me I should turn to the community page. So please help me get me some awareness on this problem
