Changing Choose From List MultiSelection from true to false.

Hello

I have a form with a table, the table has a collumn linked to a ChooseFromList.

Also I have a checkbox in the same form.

My interest is to change the mode of MultiSelection from the CFL as the value of the checksBox.

If the CFL doesn't have the posibility to change the MultiSelection parameteter, I don't know how to remove the CFL to add it with the newest behaivor.

Any idee is welcome

thanks in advance
