Set some selected props to true before assigning the dp to see if it is picking it up.

If some of the CheckBoxes are selected, and the user does the correct gesture, I have a loop that sets the 'selected' property of the model to false. I expect that to deselect all of the CheckBoxes. Yea.... not happening. --- In flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Oh, maybe you need to set selectedField="selected" > > > > ________________________________ > > From: flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> [mailto:flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> ] On > Behalf Of Geoffrey > Sent: Wednesday, November 14, 2007 8:37 AM > To: flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> > Subject: [flexcoders] Re: Item Renderer Not Updating > > > > The ResourceModel and ResourceItemModel classes are [Bindable].
