Failed to signal transition 'null' from workflow task

[pp20218]

Hi All,

I am trying a custom advanced workflow  but I am not able to finish my job .I am getting the below error. " Please correct the errors below then click Finish.* A system error happened during the operation: 06070004 Failed to signal transition 'null' from workflow task 'jbpm$17'"."

Below are my codes.

    Repository Bootstrap Sequence.

    This file specifies the initialisation (and order of initialisation) to perform during Repository startup.

    The pattern for adding new initialisation to the bootstrap sequence is as follows:

    1) Develop a bean that implements the Spring interface ApplicationListener
    2) Place the initialisation logic in the method onApplicationEvent(ApplicationEvent event)…

       public void onApplicationEvent(ApplicationEvent event)
       {
          if (event instanceof ContextRefreshedEvent)
          {
             // initialisation logic here
          }
       }

    3) Add the bean definition to this file - Note: the beans are initialised in the order they are specified.

I had taken this example from a tutorial and trying to run a new custom advanced workflow.
But getting the above mentioned error.

Can you please help me whats wrong with my code.

Thanks in advance.

must be a typo somewhere

did u start a new workflow task or are you trying with the one created with an older version?`(I changed the transition and wondered why i cant execute my wf now till i realized that i need to start a new one that worked fine)

I'm going to agree with The Storm, Alfresco is case sensitive.  It looks like no group called "engineering" exists.  When you create the group make sure you are creating the group "engineering" and not "GROUP_engineering", or "GROUP_Engineering", etc.

Hi,
Thanks for your reply.
Have you ever created a custom workflow from scratch?
I am trying to create one but failed.Even I tried with Jeff Pott's Book example.But not working for me.
If you have any help pls share.

Thanks in advance.

[solo8788]

Yes I have been able to create workflows from scratch.  Can you post a screen capture of your groups page in alfresco explorer?

And after which transition are you getting the error?

also in your bootstrap-context.xml file, update the following code.  It will make sure that any new changes to the processdefinition are used.

<props>
<prop key="engineId">jbpm</prop>
<prop key="location">alfresco/workflow/publishwhitepaper_processdefinition.xml</prop>
<prop key="mimetype">text/xml</prop>
<prop key="redeploy">false</prop>
</props>‍‍‍‍‍‍

change "redeploy" to true

Hi,

Thanks for your reply.
What I did is
(1)scModel.xml and scWorkflowModel.xml under companyHome/Data Dictionary/Model folder and selected Model Active checkbox as true.
(2)scWorkflow.properties under Company Home/Data Dictionary/Messages folder.And then using http://localhost:8080/alfresco/faces/jsp/admin/repoadmin-console.jsp url, i gave the command reload message scWorkflow
(3)web-client-config-custom.xml under Web Client Extension folder and using http://localhost:8080/alfresco/faces/jsp/admin/webclientconfig-console.jsp using the command reload.
(4)publishwhitepaper_processdefinition.xml under Workflow Definitions.
(5) uploaded ExternalReviewNotification.class under com\someco\bpm location.
(6) I created the two groups engineering and marketing.

Now when I initiate the advanced workflow, I selected "Publish White paper" workflow in the advanced workflow screen. and clicked next.
In the second screen i have 2 fields one is description and email. I gave the email address and finish.
Now nothing is happening.As you have executed this workflow.Can you help me pls.How you achieved?

Thanks in advance.
