Is there a way to programatically fire off a valuechangeevent? I have a situation where a dropdown menu sets another dropdown menu with a value. This value is necessary to update a detailed table in the master detail table relationship.
No, AFAIK, valueChangeEvent would not be triggered when the value is changed programatically. Instead, you need code the operations which you need to do when the value is changed. In this case, along with setting the value of another list, you may want to execute the detail table's model (say vo) by setting proper where clause and refresh the table.
