Hi,
I just installed the Dspace version with following specifications

I started using configurable workflow following the steps in this link and it went well for the default configuration in [dspace]/config/workflow.xml. When I used select reviewer step and used the configuration in [dspace]/config/workflow.xml I am getting the following error. I would like to know if there is a working solution for the same. I am attaching the dspace.log and cocoon.log with it.
The System used was Ubuntu 14.04

I looked only briefly, the immediate problem seems to be that either the eperson or (more likely) the workflow item is null:

https://github.com/DSpace/DSpace/blob/dspace-5.0-rc3/dspace-api/src/main/java/org/dspace/xmlworkflow/WorkflowRequirementsManager.java#L126

I don't know what it means in the bigger picture.

Meanwhile you should try following the new version of the docs:

https://wiki.duraspace.org/display/DSDOC5x/Configurable+Workflow

There have been changes to that page, at least in the way the extra database tables are created is now different (DS-2243).

helix84,

              I would like to report a slight progress in the workflow configuration. I am adding the config/workflow.xml file below. I was able to have a user selection and a final edit step. The only problem was that the last step(final edit step) was to be repeated (by reviewer) once. And also where  can I edit the clickable links shown in submission page of reviewer.? I am pretty new to this I don't know if this is right.


<!--Workflow where a reviewManager can select a single review who will then either accept/reject the item-->
    <workflow id="selectSingleReviewer" start="selectReviewerStep">
        <roles>
            <role id="reviewer" name="Reviewer" scope="item" description="These people select the item they want to review" />
            <role id="reviewmanagers" name="ReviewManagers" scope="repository" description="These people are the reviewers"/>
            <role id="finaleditor" name="Final Editor"   description="These people are responsible for final editing"/>
        </roles>


        <step id="selectReviewerStep" role="reviewmanagers" userSelectionMethod="claimaction">
            <outcomes>
                <step status="0">singleUserReviewStep</step>
            </outcomes>
            <actions>
                <action id="selectrevieweraction"/>
            </actions>
        </step>


        <step id="singleUserReviewStep" role="reviewer" userSelectionMethod="claimaction">
            <outcomes>
                <step status="0">finaleditstep</step>
                <step status="1">selectReviewerStep</step>
           </outcomes>

           <actions>
               <action id="singleuserreviewaction"/>
           </actions>
        </step>

I have made the texts bolder where I have changed the config file. The DSpace is run on ubuntu 14.04.
