[CLOSED] DirectEvent does not populate Combobox after DirectEvent Parent Refresh.
To reproduce the issue, click the trigger pulldown for State. This will cause SelState DirectEvent to populate the State ComboBox. So far so Good.
Now select California. This will call the DirectMethod ReRender the Parent FieldContainer.
Now click the trigger pulldown for County. This is where it breaks. Even though the Response populates correctly, the pulldown does not populate with the new entries.
