More than one CalculateVersionLabelPolicy behaviour has been

raaftjon — Wed, 04 Apr 2012 10:24:30 GMT

helloI would like to register my own CalculateVersionLabelPolicy for get more control about the version labes. The problem is, that the java bean registerContentWithVersionService just register a version policy:file: core-services-context.xml <bean id="registerContentWithVersionService" class=

How about you use contentservice.
Because whenever content is updated it will create new version.
and update is method from contentservice so there you can add the behavior.
I think I understood the problem correctly.

I don't use contentservice directly. I would like only define the cm:versionLabel from aspect cm:versionable.

The user should by able to choose the version label, if he will create a new version: For example 1.2.3
I don't found a solution for change version labels, except that I use a own CalculateVersionLabelPolicy.

I try also to define a VersionServicePolicies.CalculateVersionLabelPolicy bean for my custom model type:

<bean id="somco.calculateVersionLabel.behavior" class="ch.somco.alfresco.behavior.LoggingVersionLabelsPolicy"
         init-method="init" lazy-init="false" depends-on="somco-modell">
      <property name="policyComponent" ref="policyComponent" />
   </bean>‍‍‍‍

But the result is the same as noted above:
More than one CalculateVersionLabelPolicy behaviour has been registered for the type {ch.somco.alfresco.somcoModel}somcoDocument

I have found a solution for use my own CalculateVersionLabelPolic:

I overwrite the original alfresco bean configuration with a own registerContentWithVersionService and get my own CalculateVersionLabelPolic bean.

file: my-context.xml

<bean id="registerContentWithVersionService" class="org.alfresco.repo.version.VersionServiceVersionLabelRegistrationBean" init-method="register">
   <property name="versionService">
      <ref bean="versionService" />
   </property>
   <property name="namespacePrefixResolver">
      <ref bean="namespaceService" />
   </property>
   <property name="typeQName">
      <value>cm:content</value>
   </property>
   <property name="policy">
      <ref bean="somcoSerialVersionLabelPolicy" />
   </property>
</bean>

<bean id="somcoSerialVersionLabelPolicy" 
        class="ch.somco.alfresco.version.somcoVersionServicePolicies" >
</bean>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Below is my dummy example implementation. The dummy algorithm for calculate the next version is not recommended for imitation!

package ch.somco.alfresco.version;
import java.io.Serializable;
import java.util.Map;

import org.alfresco.repo.version.VersionServicePolicies;
import org.alfresco.service.cmr.version.Version;
import org.alfresco.service.namespace.QName;

public class somcoVersionServicePolicies implements
      VersionServicePolicies.CalculateVersionLabelPolicy {
   @Override
   public String calculateVersionLabel(QName classRef,
         Version preceedingVersion, int versionNumber,
         Map<String, Serializable> verisonProperties) {

      return "1.2." + RandomStringUtils.randomNumeric(5);
   }
