Question

Is there a way to make an observer that you have custom made have higher priority than the Magento one that fires on the same event. My problem is I am modifying the output of the Welcome block but the PageCache for enterprise fires on the same corecore_block_abstract_to_html_after event.

I tried putting this in my config but it didn’t work like cron jobs do.

<core_block_abstract_to_html_after>
                <observers>
                    <modify_welcome>
                        <type>singleton</type>
                        <class>groupname_page/observer</class>
                        <method>changeWelcomeText</method>
                    </modify_welcome>
                    <enterprise_pagecache>
                        <class>enterprise_pagecache/observer</class>
                        <method>renderBlockPlaceholder</method>
                    </enterprise_pagecache>
                </observers>
 </core_block_abstract_to_html_after>
