So I've finally narrowed it down to the Palette component the page uses.
When I remove the Palette it doesn't give errors. When its on screen I get
errors. This is the error I now get when I try and submit the form...

java.lang.NullPointerException

What could be wrong with the Palette to cause this? Thanks
