Category: Configuration
Version: 1.7.0.0
Priority: low
Status: new
Reported By: dkr84

Using
Mage_Core_Model_Layout::getUpdate
and
->load($template)
in Observer Event
"controller_action_layout_generate_blocks_before"
while activated the caching
LAYOUT_GENERAL_CACHE_TAG
results in an output of the cached version instead of the wanted update..
This is due to the $cacheKey in fetchFileLayoutUpdates used for loadCache().
(I think... If I'm not right correct me...)
But take a look by yourself for this Bug...

In the following testobserver, uncomment the commented lines and the update should appear as wanted.

<?php
function mainLayoutListener($observer)
{
$action = $observer->getEvent()->getAction();
$layout = $observer->getEvent()->getLayout();
$template = $action->getRequest()->template;

if (isset($template) && $template == 'popup') {
$update = $layout->getUpdate();
/* <start> the following will bugfix the issue */
// $cache_key = Mage::app()->getCache()->getOption('cache_id_prefix');
// Mage::app()->getCache()->setOption('cache_id_prefix',$cache_key.'_'.$template);
/* <end> the following will bugfix the issue */
$update->load($template);
$layout->generateXml();
}
}
?>

I forgot something...
Simple create the observer and try using the parameter ?template=popup on any page of the frontend....]]>
