Description

At the moment, workflows cannot be serialized. This makes it fairly useless because moderated page-save operations and user profile creations cannot persist between WikiEngine restarts.

We provided a partial fix for this problem, which made most of the com.ecyrd.jspwiki.workflow package serializable. This filing addresses the rest of it:

• Parameters passed to Workflow.setAttribute(String,Object) – change Object to Serializable
• Parameters passed to Step.setAttribute(String,Object) and all implementations – change Object to Serializable
• Value returned by Workflow.getAttribute(String) – change return type from Object to Serializable
• Value returned by Step.getAttribute(String) and all implementations – change return type from Object to Serializable

We will also provide a mechanism for serializing the workflow objects to disk, perhaps similar to the way ReferenceManager works.
