Tried .forgetPage() didn't it work either.
I ended up making the page an IExternalPage and doing a callback to
itself, passing the error message as one of the parameters. Then I
record the message on the delegate in the .activateExternalPage()
method. Still not sure if this is the best way, but it works.

How about using IRequestCycle#forgetPage?

I tried injecting another instance of the same page, initializing it,
and returning it from the listener method as if I were coming to it
from another page, but that did not work either.
Right now my solution is to go to another page to display the message
and give a link to "try again" to return to the editing page.
I feel like I am missing some straightforward way to reload the page
from scratch. If it was an external page I throw an exception to
redirect to it, but that would be another round trip to the browser.

Perhaps using IValidationDelegate#setFormComponent and
ValidationDelegate#recordFieldInputValue to store the new values
would work? It feels like a hack to me, but that doesn't mean it
won't work.
http://jakarta.apache.org/tapestry/tapestry/apidocs/org/apache/tapestry/valid/IValidationDelegate.html#setFormComponent(org.apache.tapestry.form.IFormComponent)
http://jakarta.apache.org/tapestry/tapestry/apidocs/org/apache/tapestry/valid/IValidationDelegate.html#recordFieldInputValue(java.lang.String)
Or else you might get away with calling IValidationDelegate#clear and
then recording your error. That might work as well.
http://jakarta.apache.org/tapestry/tapestry/apidocs/org/apache/tapestry/valid/IValidationDelegate.html#clear()
If none of it works, well, then I blame it on lack of coffee - it's
well beyond midnight here. ; )

I have a page with a form for editing an object. I am using
optimistic locking. I catch the optimistic lock exception in the
listener method and add a message to the validation delegate
indicating that another user changed the record. In this case, I
want to have the form show the current values rather than the values
just submitted by the user. Any tips for doing this?
Thanks.
