Hi, The Adobe technote provides a class for getting around the problem of having a re-selectable prompt for a combo box: ( http://kb.adobe.com/selfservice/viewContent.do?externalId=1fecccba&sliceId=1 )
I've mainly been using it like this: <mx:ComboBox id="supplierComp" dataProvider="{ new PromptArrayCollection ( [ {label:'[ all ]', data:-1} ], model.suppliers) }"/> At the time of setting it, *model.suppliers* is still an empty ArrayCollection. When it gets updated I'd like my *supplierComp* ComboBox to update appropriately. I've been going round in circles. Could someone point me in the right direction?
