[jboss-jira] [JBoss JIRA] Updated: (JBPM-426) enable jpdl schema extension via namespaces

[Ronald van Kuijk (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBPM-426?page=all ]

Ronald van Kuijk updated JBPM-426:
----------------------------------

    Affects Version/s: jBPM 3.3
                           (was: jBPM 3.0.1)

Would be great to have this for 3.3. Can anyone estimate the amount of work?

> Customizing jpdl elements in a process definition via application-specific XML-elements is currently only possible outside of any schema validation. XML namespaces are the canonical way to allow for the extension of jpdl so that  configuration data of delegation classes may be defined within an application-specific namespace and associated XML schema. In particular, this would be necessary to enable customization of jpdl elements
>   - action
>   - assignment
>   - handler
>   - controller
>   - task
> Bug #JBPM-332:
> http://jira.jboss.com/jira/browse/JBPM-332
> is somewhat related to this issue. However, resolution of JBPM-332
>   - only allows for arbitrary elements to appear inside jpdl files (without schema validation)
>   - and only for customizing assignments (leaving out action, handler, controller and task).
> Implementation of this feature request would be done via a more intelligent version of an EntityResolver (defined in org.jbpm.jpdl.xml.SchemaValidationHandle) that can return application specific schemas in addition to the default one for jpdl.
