ViewStack.vsMainDash VBox.vbDrctrDash VBox.vbParmsAndDrills ViewStack.vsDashDrills VBox.CustLevel VBox.UDAC is the hierarchy. Run code .... vsMainDash.selectedChild = vbParmsAndDrills; vsDashDrills.selectedChild = vbCustLevel; ** null reference error Debug at line that errors does show vsDashDrills = null, whereas vsMainDash = ViewStack. I have tried splattering creationPolicy="all' everywhere - of course if I do this too high up I start getting null reference errors there. (If I OK the error the app does continue with everything displayed correctly so Flex does create what it should.) If creationPolicy="all' does not work, how do I force the ViewStack vsDashDrills into existence? TIA, Mic.
