In my attached code, if you edit one item of the first VBox first TextArea,
after typing the first character you can't type anymore.

If you edit one item of the second VBox first TextArea, after leaving that
TextArea you can't change anymore of the TextAreas in VBox 2.

It seems like what's happening is that you get into a feedback loop where
you change an item in the ac and it causes the whole repeater to render
again. I got it closer with this, but it's still a bit screwy in the focus
dept.

Thanks for the suggestion. I think I may use some other component for what I am
trying to do. This funky focus issue is fairly irritating.

As for what I am trying to do, I'm building a file list in the application,
where the list is a bunch of paths to files, such as Windows .rc files.

The paths are stored in an ArrayCollection, but I need to present them to the
user so they have the opportunity to edit the paths if necessary.

I would have preferred putting them all in one TextArea, but I didn't know how
to use myTextArea.text += ac.getItemAt(myIndex); and be able to add a newline
so each AC entry is on the next line in the TextArea.

Then after the user updates the text in the TextArea, I would just write out
whatever remains in the TextArea.text to file, but once again, the newlines
must be retained in the file I write to.

In this scenario there is no updating of the AC, but I need those newlines to
take effect within the TextArea and in the written file.

Thanks again for your help Amy!

Why not just use a List? If you use itemIsEditor, I think that it will
update your AC for you.

I ended up just using a TextArea and writing the file from there. That way the user can easily delete entire blocks of lines. Line endings render fine.

Thanks for your help Amy!

Not sure how helpful I was, but you're welcome ;-)
