Live Copy moves don't work after adding mixin to protect new property of content (5.6.1)
(loosely related to http://help-forums.adobe.com/content/adobeforums/en/experience-manager-forum/adobe-experience-manager.topic.5_ciot.html/forum__bnxr-i_am_tryingtocreat.html)
I have created an event handler for AEM 5.6.1 which adds a "guid" property to the cq:PageContent node (jcr:content) of content that is created. After setting the "guid" property and saving the node, my custom mix:guid mixin is added to the same node. The mixin is defined as:
[mix:guid] > mix:referenceable mixin - guid (string) mandatory protected
The setting of the property and addition of the mixin all seems to work correctly, with one exception. When this event handler has applied to Live Copy content, moving/renaming a Live Copy master no longer propagates the change to its copies. Other features of Live Copy seem to work fine, but when I rename the master, copies do not get moved. From the /siteadmin, the copies indicate that the Blueprint page (master) has been deleted.
What could be the reason for this strange behaviour, and can anything be done to fix it?
