Question of form zone
Hi, I think I really confused this time. I searched some post about the form
zone and just try to test it.
My tml code is below:
<t:zone t:id="zoneUpdateArea">
Content before update
</t:zone>
<t:block t:id="dynamicBlock">
today's task ${task}<br />
</t:block>
<t:form t:id="addTasksForm" t:zone="zoneUpdateArea" >
<div class="enter-todo">Enter a to-do item</div>
<div class="task-textarea enter-todo"><t:textArea
t:value="task" /></div>
<div class="enter-todo">Who's responsible?</div>
<div class="enter-todo">
<select t:type="select" t:model="users" t:value="user">
<option>User 1</option>
<option>User 2</option>
</select>
</div>
<t:submit />
</t:form>
and in page class
@Inject
private Block dynamicBlock;
Block onSuccessFromAddTasksForm()
{
return dynamicBlock;
}
after i click the submit button, I got the exception:
org.apache.tapestry.runtime.ComponentEventException
A component event handler method returned the value
org.apache.tapestry.internal.structure.BlockImpl@29ed01. Return type
org.apache.tapestry.internal.structure.BlockImpl can not be handled.
Configured return types are java.lang.Class, java.lang.String, java.net.URL,
org.apache.tapestry.Link, org.apache.tapestry.StreamResponse,
org.apache.tapestry.runtime.Component.
I've test the zone with ActionLink, and it's working fine.. anything wrong
for my codes caused the error , or is the form onSuccess Handler can not
return block object??

I would guess that you are not getting the AJAX handler invoked and it's
rendering the whole page, in which case returning the block would be
innapprpriate. What browser are you using?
Try injecting the Request object and testing isXHR().
