Answer 1

Hi,
I tried nothing change
Let me re-explain my issue:
I have a table control and an "Add&Edit" button. When the user clicks on the "Add&Edit" button I need to add a new empty row to the table then changing the state of the new added cell to editable(showing a textarea and giving the user the ability to directly type text)
The add is working fine but the table.edit(...) call just after the add is not working.
Note that if the table.edit(...) isn't called just after the add it is working fine
Any idea why the edit is not working if I call it just after the add:
data.add(newPerson);
table.edit(0, firstNameCol);Thx
