Making cq-msm-lockable on jcr:title of Experience Page
I would like to introduce manual enable/disable of inheritance for jcr:title property of experience pages (cq/experience-fragments/components/xfpage).
What I did for my override is
I created cq_dialog
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:granite="http://www.adobe.com/jcr/granite/1.0" 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="nt:unstructured"
jcr:title="Experience Fragment"
sling:resourceType="cq/gui/components/authoring/dialog"
extraClientlibs="[cq.common.wcm,core.wcm.page.properties,cq.wcm.msm.properties,cq.wcm.msm.properties,cq.siteadmin.admin.properties,cq.experience-fragments.properties.tabs,cq.experience-fragments.target.properties,granite.contexthub.configuration]"
mode="edit">
<content
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/container"
granite:class="cq-dialog-content-page">
<items jcr:primaryType="nt:unstructured">
<tabs
granite:class="cq-siteadmin-admin-properties-tabs"
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/tabs"
maximized="{Boolean}true"
size="L">
<items jcr:primaryType="nt:unstructured">
<basic
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/include"
path="/mnt/overlay/ap-com/ui/components/structure/pages/xfpage/tabs/basic"/>
</items>
</tabs>
</items>
</content>
</jcr:root>And then under tabs/basic I created:
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:granite="http://www.adobe.com/jcr/granite/1.0" 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"

sling:resourceType="granite/ui/components/coral/foundation/fixedcolumns">

<column
jcr:primaryType="nt:unstructured"

<title
jcr:primaryType="nt:unstructured"
jcr:title="Title and Tags"
sling:resourceType="granite/ui/components/coral/foundation/form/fieldset">
<items jcr:primaryType="nt:unstructured">
<title
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/form/textfield"
cq:showOnCreate="{Boolean}true"
fieldLabel="Title"

required="{Boolean}true">
<granite:data
jcr:primaryType="nt:unstructured"
cq-msm-lockable="jcr:title"/>
</title>
<pagename
cq:hideOnEdit="{Boolean}true"
cq:showOnCreate="{Boolean}true"
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/form/textfield"

<tags
jcr:primaryType="nt:unstructured"
sling:resourceType="cq/gui/components/coral/common/form/tagfield"
allowBulkEdit="{Boolean}true"
allowCreate="{Boolean}true"
cq:showOnCreate="{Boolean}true"
fieldLabel="Tags"
multiple="{Boolean}true"
name="./cq:tags">
</tags>
<hideVariation
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/form/checkbox"
name="./cq:xfShowInEditor"
fieldDescription="The variation cannot be used on web pages."
text="Hide in Editor"
value="{Boolean}false">
</hideVariation>
<charset
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/coral/foundation/form/hidden"
allowBulkEdit="{Boolean}true"
ignoreData="{Boolean}true"
name="_charset_"
value="utf-8"/>
</items>
</title>
</items>
</column>
</items>
</jcr:root>However after deployment child that has connected source for live copy doesn't introduce "lock" icon on Title property.
Exactly same configuration worked properly for extension of core/wcm/components/page
Is there something missing?
