Thanks for that.
That's part of the problem, certainly, and your workaround will solve the
problem - however, one of the main goals for Zend_Layout is "Allow disabling
layouts ... from within action controllers and view scripts."
The other part of the problem is that actions which are rendered to a
response segment using setResponseSegment are rendered regardless of whether
there's a placeholder to accept them - but only if there are *no*
placeholders at all. (not sure of the terminology here, but I think my
sentiment is clear). The default behaviour is to render all response
segments to the main body content, and I believe that's inappropriate.
My other workaround (just invented, but working) illustrates this:
create a layout like
no-layout.phtml:
<?= $this->layout()->content ?>
and then
function noLayoutAction
{
$this->getHelper('layout')->setLayout('no-layout');
}
Since there is a 'content' placeholder but no 'menu' placeholder,
noLayoutAction is rendered but menuAction is not. (It would be better if
menuAction was not run, for performance reasons, but I don't see how to
achieve that).
I'm going to file this as a bug report, I think. Thanks for your help!
