OK, I think I have resolved this issue.
I was creating containerControls on the fly. Each container control includes an
FTEditField canvas.
The problem was that I was trying to operate on the canvas before embedding the
containerControl into the mainWindow.
Since the FTEditField.open event is where it is initialised, and the doc
created, I was trying to operate on the doc, prior to its initialisation.
Solution was to create a new Container Control, Embed it within the Window and
then operate on it.
