How to return a component without a form (T5.1.05)
The page template looks like:
...
<t:form t:id="theForm" zone="listZone">
<table>
<t:zone t:id="listZone"/>
<tr>
<td><t:submit /></td>
</tr>
</table>
<t:block><t:myComponent t:id="myComponent"/></t:block>
</t:form>
page class:
class Index {
@InjectComponent
private MyComponent myComponent;
Object onSuccess() {
return this.myComponent;
}
}
MyComponent template:
<tr>
<td><t:select t:id="list" label="List" blankOption="never"
model="objects" encoder="objects" value="object" /></td>
</tr>
MyComponent Class:
class MyComponent {
......
}
When I click submit button, I got a error: Render queue error in
SetupRender[Index: myComponent.list]: The List component must be enclosed by
a Form component.
What's wrong? How can I implement this feature?

Thanks for replying. But I've abandoned ajax.

It's not quite true, but close enough.
All form components have to have a FormSupport environmental object
available when they render. So you can have form fields that are in
blocks on non-rendering pages and pull those blocks into the rendering
page and everything works fine. The problem occurs when you do an
ajax request where you want to update some small portion of the page,
itself contained within a form, with some form-based content. In that
case, the "naive" solution will fail. Eg:
<t:form>
...
<t:zone ...><!-- some zone to be updated via ajax, within the form;
we want it to render form fields. --></t:zone>
...
</t:form>
When you update the zone with some form-field-containing content,
you'll get a failure because the form fields won't have a FormSupport
object available to them in the environment.
This is what, eg, the FormInjector component tries to solve.
Unfortunately, it seems geared toward use with, eg, AjaxFormLoop. In
any event, it's a bit unwieldy to use on its own.

Sorry, it's not true, my mistake. As long as the input doesn't depend on
form events, it can be placed in a sub-component.

Is that true? Anyone knows if there's a reason for this? Cause
otherwise, you should
file a bug report

This limitation has been a blocker for me too. All form components need to
be enclosed by a form in the same template.
I guess you need to use some other strategy, for example by subclassing the
select component? I would like to se some nice suggestions on this, as this
is a real requirement for me too.
