Hi,
I asked this question a short while ago; its caused by people clicking a
link twice too rapidly; see the answer from Byran Lewis:
If you search for "page recorder locked" in the archives (for instance,
http://marc.theaimsgroup.com/?l=tapestry-user), you'll find several postings
about this. The usual approach is to make your custom Engine ignore the
exception, or add javascript to your buttons to disable a button once it's
clicked, or synchronize multiple requests from the same user in the
ApplicationServlet.

Hi all,
What does this exception mean?
I get this when I try to assign a value to a property
that has a persistent flag set to "yes"
Thanks
