Thanks Dominic, I tried that, out of desperation (it doesn't seem so efficient) and it erupted in the famous TypeError#1009 (null object somewhere)
Why is this so hard? I know the coordinates on the grid where I need the new values printed to screen. Why can't I invoke function like this: myDataGrid.invokeGridCellSetterFunctionForRowCol (myrow, mycol); uh... because there is no such function? I don't need active or passive event listeners or any other hi-tech poo. I just want to print some stuff on screen there: the latest greatest stuff. As it is, the DataGrid and it's recycled renderer family seems content- happy, this is- to show the stale data: the old content. --- In [email protected], "Dominic Pazula" <[EMAIL PROTECTED]> wrote: > > Try setting a new ArrayCollection with all the values from the > changed ArrayCollection.
