Re: 'Write Once' won't allow writes to a checkbox after window is saved

Using "Write Once" on a check box is actually saving a "False" value on save so it is writing to this once and will not be able to edit after save.  You may consider presenting an action tied to a window with read/write on this checkbox to be able to check this option later.  Another option is to go away from a check box and use a dropdown with a default value of "Nothing" using the write once enabled for this.
