Correction, I do not have a name property set in the PROVIDER, but in the repeater there's a name attribute on of one of the components that's set like name="mydataprovider.name_element" If I clear out the data it shouldn't cause this problem because the repeater shouldn't go through any iterations. If I remove one of the elements in my array, the rest still have the "name_element" set so it shouldn't be a problem in that case either....
Unless of course there's something I don't know about using a "name" in a repeater or something like that. --- In [email protected], "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Do you have a 'name' property in your data provider objects? > > > > ________________________________ > > From: [email protected] [mailto:[EMAIL PROTECTED] On > Behalf Of Ryan > Sent: Monday, October 15, 2007 4:29 PM > To: [email protected] > Subject: [flexcoders] Very strange runtime error with a repeater. > > > > I've used repeaters before so I definitely know how they work as a > whole.
