Unable to set list value in Aras 11.5 using setCombo()

Hi All, I am trying to set a list with labels and values to the currently selected cell in Aras 11.5 using the below code - currSelCell.setCombo(labels,values) The below error occurred, and the cause of the issue is not known. Error: List Id is undefined The new values got added to the list in Aras and Database, but are not getting reflected in the drop-down of the property. The same code works fine in Aras 9.2. Can someone please look into the above error and help me find the root cause of the issue as I have tried all the available API methods to set the drop-down (setCellCombo(), setComboList(), setValue(), getting the current cell and then used these methods also), but no luck. Thank you in advance!! Regards, Charita
