I have dynamic content in my block which is cached so I exclude this block from cache in the easiest way. I've created cache.xml which looks like:

<?xml version="1.0" encoding="UTF-8"?>

and i've created container:

class My_Package_Model_Container_Category_View extends
           const PREFIX = 'MY_CATEGORY_VIEW';

and it works great. the block is excluded from FPC, but the problem is that after refreshing the page I've got exception.

Fatal error: Call to a member function getChild() on a non-object

in this line:


any idea how to fix that? I've spent 2 days on it and still cannot resolve it.

I resolved this problem this way. I created the observer which exclude category view from FPC. It's not the best way because I needed only to exclude one block from this view but it works...

My observer:

class MyCompany_Catalog_Model_Observer
    public function processPreDispatch(Varien_Event_Observer $observer) {
        $action = $observer->getEvent()->getControllerAction();

        if ($action->getFullActionName() === 'catalog_category_view') {
            $cache = Mage::app()->getCacheInstance();
