create dependent lists which are based on service connections?

Content

Hi All,

We have 2 rest endpoints from and showing the values in 2 comboboxes separately (each service connection is tagged to each combobox respectively) - this works fine.

 Now, we need to add dependent list on the second list based on the value of first list.

 Note: second list has code and value from service connection and there is another attribute "thirdAtt" based on which we need to filter this rest from the code of first list.

 

 We have created a value change listener for the first combobox, and within that we are calling second rest api with query parameter and assigning the result to a variable(type of second rest api), and assigned that variable to a combobox but it is not working.
