I have a similar issue on an update page with dynamic dropdowns
I did set up the database table as a combined table, as shown in the help
Then i did the following:
1) Set Parent List Values from recordset for the parent list - for the selected ValueI used the binding from the recordset i wanted to update
2) I applied the "Populate List From Array" Behavior to the onChange event of the Parent List
I apply the following Dynamic Drop Down Behaviors to the onLoad event of the body tag:
3) Populate List From Array - Set this up the same way you would for the Parent list form element on change event.
So far it works fine - the correct value gets selected in the parent list and the corresponding values populate the child list
4) Set Selected in list - Target List: Child List List, Value: Useing the binding from the recordset I want to update. But no value in the child list gets selected.
Where did I miss something to get the correct value of the child list selected?
