Custom Metadata gets not overridden

[Jannik]

Hey guys,

I followed this official Alfresco Guide LINK for adding custom Metadata to a file which is uploaded in a process by using "Publish to Alfresco". If I upload the same file with different Metadata-values via the process, the file gets auto-versioned (which is great), but my custom Metadata in version 2 are the same as in version 1 - nothing changed. If I downgrade the file to version 1 the custom Metadata-values are empty.

The custom Metadata file is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<model name="myc:customModel" xmlns="http://www.alfresco.org/model/dictionary/1.0">
  <description>Custom Model</description>
  <author></author>
  <version>1.0</version>

  <imports>
      <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d"/>
      <import uri="http://www.alfresco.org/model/content/1.0" prefix="cm"/>
  </imports>

  <namespaces>
      <namespace uri="http://www.mycompany.org/model/content/1.0" prefix="myc"/>
  </namespaces>

  <types>
      <type name="myc:caseDocument">
          <title>Case Document</title>
          <parent>cm:content</parent>
          <mandatory-aspects>
              <aspect>myc:caseData</aspect>
          </mandatory-aspects>
      </type>
  </types>

  <aspects>
      <aspect name="myc:caseData">
          <title>Case Data</title>
          <properties>
              <property name="myc:caseId">
                  <title>Case ID</title>
                  <type>d:long</type>
              </property>
              <property name="myc:caseName">
                  <title>Case Name</title>
                  <type>d:text</type>
              </property>
              <property name="myc:caseOpenedDate">
                  <title>Case Opened Date</title>
                  <type>d:date</type>
              </property>
          </properties>
      </aspect>
  </aspects>
</model>

Each version should have its own Metadata - that's logical...

Anyone has a clue how I can solve this?

Cheers, Jannik
