How to stop execution of an action?

[k00ni]

Hi,

we have an action for example .../syncml/sync. This action has
different checking-function. If one function detects problems than the
action execution must be stopping. How can we do this?

Is an exit ok?

quote k00ni (27.6.2009):

yes, but please throw an exception before that.

examples are e.g. in the serviceController at transitiveclosureAction()
...

// fetch start resource parameter
if (isset($this->_request->sr)) {
$resource = $this->_request->getParam('sr', null, true);
} else {
require_once 'OntoWiki/Exception.php';
throw new OntoWiki_Exception('Missing parameter sr (start resource)!');
exit;
}

regards
