How about getting a previous version of a document?

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hi,
I'm trying to define a workflow to regress to a previous version of a document.  I've seen in Version Store Design and API  http://wiki.alfresco.com/wiki/Version_Store_Design_and_API#get  that exist a get method to do this; but in a workflow script this function seems to be not supported…

Someone can help me?

We'll continue to expand the javascript api in each release, but if there's a function missing, you can fall back to java in a workflow process definition.

e.g.

  <task-node name="a">
        <task name="a" swimlane="assignee" />
        <transition name="approve" to="approved">
           <action class="my.JavaClass"/>
        </transition>
  </task-node>
‍‍‍‍‍‍‍

class my.JavaClass implements ActionHandler
{
   public execute( ExecutionContext executionContext )
   {
       …
   }

}‍‍‍‍‍‍‍‍

If you want access to Alfresco services in your ActionHandler, then follow the pattern in the class AlfrescoJavaScript.java.
