We'll I got it to work using a completionCreateHandler.
Basically where the datagrid is complete, it calls the dataGrid_creationCompleteHandler function which checks the row count for the datagrid.
I also had to change the dataGrid.rowCount to = Array(getFLOWTESTResult.lastResult).length;
, which gives me the following warning... but it still works.
Description Resource Path Location Type
1112: Array(x) behaves the same as new Array(x). To cast a value to type Array use the expression x as Array instead of Array(x). FireFlow2.mxml /FireFlow2/src line 26 Flex Problem
