In app I am supposed to test, there are some MX components, one of which is AdvancedDataGrid. I am able to Highlight it and use some RO properties, but methods like GetCellData does not work, always returning null:

<font class="small">Code:</font><hr /><pre> msgbox Browser("creationTime:=").FlexApplication("id:=fle xapp").FlexAccordion("id:=accordion").FlexBox("id: =resultsVbox").FlexAdvancedDataGrid("id:=breachDat aGrid").GetCellData(3,5)</pre><hr />

This IMHO should work as there are 10 columns and more than 50 rows of data.
Could it be MX components issue? I assume Spark ones are better supported.
