Drag and Drop on Page Component

Hi,

I have an edit configuration which looks like this:

    <?xml version="1.0" encoding="UTF-8"?>
    <jcr:root xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
        jcr:primaryType="cq:EditConfig">
        <cq:dropTargets jcr:primaryType="nt:unstructured">
            <title-data-reference
                jcr:primaryType="cq:DropTargetConfig"
                accept="[.*]"
                groups="[title]"
                propertyName="./title" />
        </cq:dropTargets>
        <cq:listeners
            jcr:primaryType="cq:EditListenersConfig"
            afteredit="REFRESH_PAGE" />   
    </jcr:root>

The drop taget in the JSP is defined like this:

    <div class="<%=DropTarget.CSS_CLASS_PREFIX%>title-data-reference">
        <b>Drop it here</b>
    </div>

When I use this in a "normal" component drag and drop from the content finder works fine. When I *** the same edit configuration and the same drop target code to my page component, which has sling:resourceSuperType="foundation/components/page" specified, the drop area is not recognisable as a drop area.

Both component and the page component dialog have a pathfield widget defined:

    <?xml version="1.0" encoding="UTF-8"?>
    <jcr:root xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
        jcr:primaryType="cq:Widget"
        fieldLabel="Titel"
        name="./title"
        rootTitle="Titel"
        xtype="pathfield"
        rootPath="/etc/xxx/titles">
    </jcr:root>

Is a page component different from a "normal" component so that it does not accept a drop? Am I missing something else?

Thanks in advance,

Ronald
