[flexcoders] Re: Datagrid with bound dataProvider not updating.
Thanks for all the responses! I took the advice and switched to using ArrayCollection and all is working fine now (without hammers :-)) Thanks again! --- In flexcoders@yahoogroups.com, Tracy Spratt [EMAIL PROTECTED] wrote: I think Alex called invalidateDisplayList a big hammer.

Call refresh() on what? The dataGrid doesn't have a refresh() method. It is an Array rather than an ArrayCollection. Could that be the problem? This could require a lot of refactoring! Scratch all that... myDatagrid.invalidateDisplayList() did the trick! Thanks! --- In flexcoders@yahoogroups.com, Angus Johnson [EMAIL PROTECTED] wrote: arrayCollection or array?

RE: [flexcoders] Re: Datagrid with bound dataProvider not updating.
We'll wrap the array in an ArrayCollection, so call dataGrid.dataProvider.refresh(). Or dataGrid.invalidateList() However, neither approach may work until you refactor to modify the ArrayCollection and not the array. Arrays do not have change notifications so we can't see what is changing. ArrayCollection does.
