Hey Alex, Thanks for your reply. It was very helpful, my comments are inline below:
It might be a problem with the offsets given to the method. At a first glance I would say that the interval to replace should be (to cover the case when start > 0):
jTextArea.replaceRange(suggestion, start + lastIndex, start + lastIndex + ADD_NEW.length());
Doh! Yes, of course you are correct, my offsets should be from `start`. When I make that change, then replaceRange does indeed work.
Perhaps you can also resolve the use case without a timer. CIValue#getInsertString() gets called after the user chooses a value in the content completion window, at the moment when we have to decide what to insert in the document. I suggest overriding this method and getting the value from the user then. I've tested it in Oxygen v17.1 and it worked well.
I was hoping that you might suggest something like that :-) I just used `Timer` as it enabled me to get something working quickly without having to dig into the Oxygen API in too much detail. I have now switched to overriding CIValue#getInsertString() and it is working well. Thanks again. Adam. -- Adam Retter skype: adam.retter tweet: adamretter http://www.adamretter.org.uk
