JIRA NullPointerException when switching Workflow scheme

[ALO]

Hi all,

I have a problem since I imported a workflow as xml and assigned it to a production project. The workflow itself worked fine on my test system and also looked fine as a diagramm in production.

I noticed in production that in the Workflow Text-Modus 3 Step-Names are not linked with the proper Status and 2 don't have any:

Now, although I changed this missfits, I can't assign the new Workflow (Workflow-Scheme) or the old one to the Project, since I keep getting the same java.lang.NullPointerException:

Cause:
java.lang.NullPointerException

Can anyone help please?
Many thanks!

Problem solved:

https://confluence.atlassian.com/display/JIRAKB/%27NullPointerException+in+SelectProjectWorkflowSchemeStep2.getNumAffectedIssues%27+Due+to+Workflow+Step+that+Doesn%27t+Have+a+Linked+Status?src=search

Two steps had no linked statuses, therefore the nullpointer exception.

I created two temporary statuses (Administration >> Issue Settings >> Statuses > Add New Status). These new statuses automatically got the id's that were missing, and that the pointer was pointing to. After that the exception was gone and I could replace the scheme.

Sorry, we have v5.2.6

The Jelly Script didn't work:

[Stefan Niedermann]

i tried the same jelly script and get the same error (jira 5.1.8). do you have any information, how i can assign a scheme with jellyscript in my jira version?

regards

[RambanamP]

try with the jelly script

<JiraJelly xmlns:jira="jelly:com.atlassian.jira.jelly.enterprise.JiraTagLib" xmlns:core="jelly:core" xmlns:log="jelly:log">
 
  <!-- Grab managers. Do it using ComponentAccessor now which gives better compatibility in Jira 5! r -->
  <core:invokeStatic className="com.atlassian.jira.component.ComponentAccessor" method="getWorkflowSchemeManager" var="workflowSchemeManager"/>
  <core:invokeStatic className="com.atlassian.jira.component.ComponentAccessor" method="getProjectManager" var="projectManager"/>
 
 
  <!-- Get the project with key "MYPROJECT" using ProjectManager -->
  <core:invoke on="${projectManager}" method="getProjectObjByKey" var="project">
    <core:arg type="java.lang.String" value="MYPROJECT"/>
  </core:invoke>
<log:warn>Project ${project} found</log:warn>
 
  <!-- Get the workflow scheme "myScheme" -->
  <core:invoke on="${workflowSchemeManager}" method="getSchemeObject" var="scheme">
    <core:arg type="java.lang.String" value="myScheme"/>
  </core:invoke>
<log:warn>Scheme ${scheme} found</log:warn>
 
  <!-- Assign scheme to project -->
  <core:invoke on="${workflowSchemeManager}" method="addSchemeToProject" >
