That appears to be the result of (from: http://tapestry.apache.org/tapestry5/tapestry-core/guide/rendering.html)
:
"If a method returns a true or false value, this will short circuit
processing. Other methods within the phase that would ordinarily be
invoked will not be invoked.
Most render phase methods should return void, to avoid unintentionally
short circuiting other methods for the same phase."

Something else i've noticed ... if i modify my mixin to always

So if I've read the JIRA correctly does this mean that simply
implementing @BeginRender and @AfterRender in my mixin is not enough
- I would actually have the modify the component (in this case
textarea)? to check for short-circuiting?

Subject: RE: Mixin render phases
hi toby,
i think i had the same issue some time ago
i was also trying to create a mixin for enabled/disabled
handling by short circuiting the render phases. but the
render phases (or at least the short circuiting) do not
work as i was expecting :).
maybe you can take a look at the problem description (it think
there are a lot of details in the comments) of the jira at
https://issues.apache.org/jira/browse/TAPESTRY-1805
and comment on it.
g,

Mixin render phases
Hi guys,
I'm trying to show/hide an html element based on Robert's recent
suggestion (Re: how do we secure our views) but I've hit a minor
problem.
The mixin's @BeforeRender method is being called but then tapestry
complains that the component (textArea) is unbalanced. I'm using the
component and mixin in a custom component, not a page. Here is the
code
The mixin:
public class Visible {
@Parameter(required=true)
private boolean visible;
@BeginRender
boolean render() {
return visible;
}
}
The custom component:
@Component(id="reason", parameters={"value=violation.message",
"visible=true"})
@Mixins("visible")
private TextArea reason;
The custom component's tml
<t:form>
<t:textArea t:id="reason" />
<input type="submit" />
</t:form>
When the component renders I get the following exception:
"Render queue error in
CleanupRender[TestViolations:violations.reason]:Component
TestViolations:violations.reason has rendered unbalancedelements;
either
it has started an element with MarkupWriter.element()and not
followed up
with MarkupWriter.end(), or it has invokedMarkupWriter.end() without
first
invoking MarkupWriter.element()."
"TestViolations" is the page which includes the custom component,
"Violations" is the custom component
Does anyone have any ideas?
Thanks
Toby
