Apex 4 Cascading LOV's how to set a child LOV back to null return value
807644Nov 12 2010 — edited Nov 14 2010Hi,
My problem is I am using the new Dynamic Actions to implement Cascading LOV functionality in Apex 4 which means not having to submit the page to update child LOVs after parent LOV changes.
What I am finding is that when you change the parent LOV value then the child LOV (which has a null return value) is not defaulting to the null return value (in my case no selection should return -1) if its list is filtered to a different set of values which doesnt have a valid selection. The child LOV is left without a selection when I need it to default back to the null return value (-1, representing all values).
Also I was hoping to do this before the page is submitted so the filtering down the hierarchy of LOVs will work where the child is null (-1, meaning all values) and in turn its child LOV(s) will filter also from the null child value.
Any help would be much appreciated.
Thanks
