Avoid empty validation on DropdownByKey
How to avoid the unwanted validation of blank entry selection, created by the framework, when rendering a Dropdown on Web Dynpro Mobile?
The problem is:
- We have a Dropdown UI element bounded to a list from BAPI output table;
- On the application, the user selects a value and fires any action, by pressing a button or something;
- Then he remember that this field ought to be empty and select the blank entry;
- On firing any other action, even a roundtrip to the server, a validation occurs, with error message like "Value ' ' not on the enumeration range"...
Is there a solution on this?
Ps: We are using WindowsMobile5 devices.
