Hello

I've found something strange when using the Publish all it's subpages and include unpublished child pages on a copied node containing "Tags" DataType. Tags's content is not updated in the umbraco.config (and also not in the cmsContentXml sql table).
The following steps to do this :

1. In the backoffice, create somewhere a node containing a "Tags" DataType. Write "abc", hit "enter", write "cde" and hit "enter" to create the tag and click on the "Save and publish" button (in the tab part).
     Publication Status of the node is updated with the Last published date (Last published: 29/04/2013).
     In the umbraco.config, the content look like this :

<myTags><![CDATA[abc,cde]]></myTags>

2. In the content panel (on the left side), copy the node in another folder (without checking the "Relate copied items to original).
        The copied node has as Publication Status : This item is not published.
       
3. In the content panel, right click on the node and choose Publish. Check both "Publish and all its subpages" and "Include unpublished child pages". Click on the publish button of the modal display box.
     In the umbraco.config, the new node is present but the value of the "Tags" DataType is :

<myTags><![CDATA[]]></myTags> instead of <myTags><![CDATA[abc,cde]]></myTags> 

It was also not updated in the cmsContentXml sql table.
     The Publication Status is : Last published: 29/04/2013

Is this a normal behavior ?
     
NB :     
    If I do a save and publish (in the tab part), it's updated in the umbraco.config file with the right value and the sql table.
    If I add another Tag, then "Save" the node without publishing and in the content panel, right click on the node and choose Publish. Check both "Publish and all its subpages" and "Include unpublished child pages". Click on the publish button of the modal display box. It's also correctly updated in the umbraco.config file and sql table.

Tested on Umbraco 4.11.5
Tested on a clean Umbraco 4.11.7
