Java ArrayList Serialization issues

I seem to recall an issue when you are trying to serialize ArrayLists in Java. I have run into the problem and cannot figure it out.

I send an ArrayList through a socket and then when I send it again, the ArrayList doesn't get transmitted correctly (even though the ArrayList has been modified) I recall this has something to do with not flushing the stream or something. Can anyone help me remember the issue and how to solve it?

If by 'doesn't get transmitted correctly' you mean 'doesn't get updated at the peer' you need to call ObjectOutputStream.reset() before re-sendng an instance after it's been changed.
