Description
Datagrid shows blank screen when applying sort to dataprovider, using the scrollbar causes it to display correctly.
Download zip fxp project here:

Steps to reproduce:
1. launch the app (it will populate the datagrid with values)
2. choose a different date in the date picker on the top left
3. use the scroller on the right-hand side to scroll through the datagrid, the datagrid will then render properly
Actual Results:
the dataprovider will get updated but the datagrid doesn't update properly, instead it just remains blank
Expected Results:
The datagrid shows the new results. When the user uses the scrollbar on the right the datagrid renders properly and shows the results.
Workaround (if any):
This is a hack suggested by Alex Harui, basically it entails setting the scroll position programatically to force the datagrid to render properly
//////////////////////////////////////
var oldvsp:Number = dgTransactions.grid.verticalScrollPosition; // record the current scroll position
_dateFilteredCollection = new ArrayCollection(dateFilteredArray);
applySort();
applySearch();
dgTransactions.grid.verticalScrollPosition = oldvsp + .1; // move the scroll position to force the datagrid to show the data correctly
dgTransactions.grid.verticalScrollPosition = oldvsp; // restore to the original scroll position
Which SDK and Flash Player version? I'm unable to reproduce this on both OSX and Win7 using the SDK version 4.9.1.
