I have a critical problem with the undo/redo support in my
application: It works fine for test that is inserted manually (by the
user), however, it throws an exception when the user attempts to undo
a change to the document that was made programmatically, i.e. when the
program performs a find/replace operation, if the user attempts to
undo this, it throws an arrayIndexOutOfBoundsException as it hasn't
accounted for the changes.

I have tried to use getDocument().remove()
and getDocument.insertString()

but these are not doing the job. Please can someone tell me how to
account for this problem.

Many thanks in advance
