set text cursor in editable datagrid with adobe flex 3

Question

Hi,

when clicking on a row in this editable datagrid, the whole text is selected. How can I set the cursor to the first character. I've tried itemEditBegin(ning) and expected to be able to use for the ItemEditor a method like setSelection()...

Please let me know, if you need anykind of additional information!

Thanks, Werner
