Jochen Kemnade commented on TAP5-2308:
--------------------------------------

It looks like the fragment's client ID that is passed to the {{t5/core/form-fragment:linkTrigger}} is null. Probably the initialization happens to early.

> I am trying to use FormFragment with TriggerFragment on checkbox in the way it is documented at: http://tapestry.apache.org/5.3/apidocs/org/apache/tapestry5/corelib/components/FormFragment.html
> Here is my template snippet
> --------------------------------
> {code}
> <t:beaneditor object="job" include="title,description,proposalDeadline,jobCompletionDeadline,tags,canBeDoneRemotely">
>   <p:canBeDoneRemotely>
>     <t:checkbox t:id="canBeDoneRemotely" value="job.canBeDoneRemotely" t:mixins="triggerfragment" fragment="jobAddress"/>
>     <t:label for="canBeDoneRemotely"/>
>   </p:canBeDoneRemotely>
>  </t:beaneditor>
> <t:formfragment t:id="jobAddress" visible="!job.canBeDoneRemotely">
>        <t:beaneditor object="job" include="address" />
> </t:formfragment>
> {code}
> The error message I get
> --------------------------------
> The event is bound properly and gets triggered when clicking on the checkbox, but I get the this error message:
> Uncaught Error: Attempt to wrap a null DOM element dom.js:411
> wrapElement dom.js:411
> update form-fragment.js:36
> wrapped dom.js:49
> jQuery.event.dispatch jquery.js:4624
> jQuery.event.add.elemData.handle jquery.js:4292
> The reason:
> ------------------
> In form-fragment.js at line 36 spec.fragmentId is undefined.
