I'm trying to use the token component on a form to ensure that a user
doesn't submit the form more than once. Whenever I try and submit the
form a second time, I get a NPE. I'm using it in Clay, if that makes
any difference. The code is simply:
<form>
<span jsfid="token" id="token" />
<span jsfid="message" for="token" class="validation-msg" />
...
</form>
I'm using the 1.0.3-SNAPSHOT jars from the maven-snapshot-repository,
last updated on April 19th. Any ideas why I'm getting the below NPE?
It's working with myfaces 1.1.1. The exception points at the findComponent but I would have guessed that we are not populating one of the message component attributes.
Try adding the showSummary attribute to the message component.
<span jsfid="message" for="token" showSummary="true" />

Sorry it's taken a while to get back to this, but it was suddenly
decided to change the whole flow of the app I'm working on.
I tried adding the showSummary="true" attribute and am getting the same
exception. Any other ideas?
Thanks,
