Looks like there are a couple of bugs in there. File the bugs against Adobe if you have an Adobe support contract, otherwise file against Apache Flex.
I used the following hack in applyDateFilter that appears to work. If you don't change the scrollposition, it doesn't cause a full update of the screen. var oldvsp:Number = dgTransactions.grid.verticalScrollPosition; _dateFilteredCollection = new ArrayCollection(dateFilteredArray); applySort(); applySearch(); dgTransactions.grid.verticalScrollPosition = oldvsp + .1; dgTransactions.grid.verticalScrollPosition = oldvsp; -Alex --- In flexcoders@yahoogroups.com, Wouter Schreuders <wschreuders@...> wrote: > > Hi Alex > > To replicate the problem. > > - launch the app (it will populate the datagrid with values) > > - choose a different date in the date picker on the top left > > - the dataprovider will get updated but the datagrid doesn't update > properly, instead it just remains blank > > - use the scroller on the right-hand side to scroll through the datagrid, > the datagrid will then render properly > > Thanks > > Wouter > > On 26 April 2012 08:37, Alex Harui <aharui@...> wrote: > > > ** > > > > > > What are the steps to reproduce the problem? > > > > > > > > On 4/20/12 12:54 AM, "Wouter Schreuders" <wschreuders@...> wrote: > > > > > > > > > > > > > > I've made a simple test case in which I can replicate the problem.
