I suspect this might be a bug. I'm seeing warnings in my logs every now
and then that form submissions that should be XHR aren't and thus
returned a block which isn't a valid return value.
Howard, anyone?

It's not being submitted using an XMLHttpRequest - that's the problem I need help with. One of the elements passed to
Tapestry.init() is "linkZone":[["actionlink","lor"],["resort","lor"]] so the
form should be linked to the zone.
The zone looks like this:
<div t:type="zone" t:id="lor">
<t:delegate t:to="lorBlock"/>
<t:block t:id="lorBlock">
<ul>
<li t:id="pagedResultsList" value="item"
itemsPerPage="25">
<t:citation.defaultShort source="item"/>
</li>
</ul>
<t:resultsPageLinks t:id="pageLinks"/>
</t:block>
</div>

How is your zone defined?
Also, check if the form is really submitted using an XMLHttpRequest.
I've seen this fail a couple of times lately, hence my suggestion to
check Request#isXHR.

Thanks for the reply Filip. I have bound the zone parameter on the
form like this:
<form t:type="form" t:id="resort" t:zone="lor">
<t:label for="sortType"/>:
<select t:type="select" t:id="sortType"
t:validate="required"/>
<br/>
<input type="submit" t:type="submit"
t:id="resortButton" value="Resort"/>
</form>
<t:actionLink t:zone="lor"
t:context="literal:oldestFirst">oldest first</t:actionLink>
The action link works in an Ajax way, but the form submit doesn't.
The even handlers are:
Object onSubmit() {
results.resort(sortType.name()); // sortType
is the enum bound to the select box.
return lor;
}
Object onAction(String st) {
results.resort(st);
return lor;
}
The form submit does the resort, but refreshes the entire page. I
just can't figure this out.

Hi Andy,
Form has a zone parameter, if you bind it the zone will be updated
when
the form has been submitted.
Just make sure to check Request#isXHR to see if it's actually an
Ajaz-request before you return a block/component or Tapestry will
bark.
The solution, then, is to just do a normal return like you would
from a
non-Ajax event handler.
http://tapestry.apache.org/tapestry5/tapestry-
core/ref/org/apache/tapestry/corelib/components/Form.html
has the lowdown on events emitted by Form, it's at the bottom of the
page.

Is it possible to update a zone as a result of a form submission,
rather than having the entire page refresh?
I have a form with a select box and submit button to change the
sorting of a list of search results, and when I return a zone from
the
event handler method onSubmit() the entire page is refreshed rather
than just the zone. The zone updates correctly from other
actionlinks
on the page and their onAction() event handler. Is the answer to get
the form to fire action events somehow?
I admit that I'm still a little confused still by events, is there
a
complete list of the event types and their uses/behaviour somewhere
that I've missed?
