FPM multiple dropdown UI - error - entered value not in list of valid values

Hi All,

I have 2 Dropdown UI Lists.

The 2nd dropdown is dependent on the values from the 1st dropdown.

This is in a FPM_FORM_UIBB component.

Problem is - if I select a value in 2nd dropdown and then try to change the value in dropdown 1 , I get a error message - entered value is not in valid values.

Blank values is already considered in the list - so I'm not sure whats causing the problem.

The changes are written in the GET_DATA method of the feeder class.

Dynamic Dropdowns in FPM - error "entered value is not in valid values."
