JCR node type nt:file is not allowed as child's node type for parent node type

Question

I add one "soc:music" (nt:file) child node (same as original "soc:avatar" node) into the exoplatform profile entity, but it fails when store into JCR. I google the error, seems little mentions about it. Do you know how to fix it? thanks. The weird thing is the original "soc:avatar" node works well.

<nodeType name="soc:profiledefinition" isMixin="false" hasOrderableChildNodes="false">
...
  <childNodeDefinition name="soc:avatar" defaultPrimaryType="nt:file" autoCreated="false" mandatory="false" onParentVersion="COPY" protected="false" sameNameSiblings="false">
    <requiredPrimaryTypes>
      <requiredPrimaryType>nt:file</requiredPrimaryType>
    </requiredPrimaryTypes>
  </childNodeDefinition>

..
  <childNodeDefinition name="soc:music" defaultPrimaryType="nt:file" autoCreated="false" mandatory="false" onParentVersion="COPY" protected="false" sameNameSiblings="false">
    <requiredPrimaryTypes>
      <requiredPrimaryType>nt:file</requiredPrimaryType>
    </requiredPrimaryTypes>
  </childNodeDefinition>
</childNodeDefinitions>

Answer 1

Be careful when changing the nodetype definition like this, it may effects to the existing data in the system. You have to think about the "migration" for this modification. We're using Chromattic, therefore the nodetype's definition must be mapped with java class. You have changed soc:profiledefinition, therefore you have to added soc:music definition in the ProfileEntity.java as well (at package org.exoplatform.social.core.chromattic.entity).

Hope it helps, Minh
