I don't think something is firing..
I had it working with the other code.. creating the empty VO and
assigning the values one by one and then passing the VO to the command
to populate the MyModel SelectedVO..
When I chose a row a form I had started populating using this:
{MyModel.getInstance().SelectedBudgetVO.amount.toString()}but when I changed the changeHandler to just MyModel.getInstance().SelectedBudgetVO = event.target.selectedItem as BudgetVO; They stopped populating On Tue, Oct 7, 2008 at 10:17 AM, Tim Hoff <[EMAIL PROTECTED]> wrote: > "I have no idea why it wont work with an ArrayCollection" > > Because your ArrayCollection is a collection of VO's, not a collection of > ArrayCollections; although there may be ArrayCollections as properties of > the VO.
