property-specification/page-recorder exception
I have declared several variables in my .page file using the
property-specification element and delcared the page specification java
class abstract and included abstract getter/setter methods for these
variables. storedValues the variable referred to in the exception below, is
one of these properties and is a boolean value which I reset to false
during form submission once validation is passed.
Everything seems to work fine when 95% of the time but if I submit the page
and then re-click on the submit link before the next page has been rendered
I recieve the following exception:
org.apache.tapestry.ApplicationRuntimeException
Page recorder for page entitlement.otherInformation is locked after a commit(), but received a change to property storedValues of
component entitlement.otherInformation.

I am concerned by this behaviour as it does not seem an unlikely scenario
for a user to click a submit link twice quickly. Is there something that I
am doing wrong here and if so how can I prevent this from happening?
Thanks in advance,
