I have setup a AdanacedDataGrid with Hierarchical data. At second level I am displaying couple of PieCharts. Two things happen, when I expand to view a graph and the collase it, if other rows of the dataGrid were overlaped by the graph then I get the same graph again, and/or sometimes if I expand, then scroll down to expand another row I get the null pointer expection as described in the above bug. Has anyone else encoutered this?
I hope I was able to give you guys a some what clear pic of what is happing. I have spend lot of time figure this out and now I hope I don't have to scrap the who UI and figure out some other way to display my data.
I have tired to compile in Flex 4 beta, but there are whole lot of other issues that my head is spinning.
