Hello,

I followed the workflow tutorial at http://ecmarchitect.com/alfresco-developer-series-tutorials/workflow/tutorial/tutorial.html#using-th...
Everything looked great until I completed step 1 of WhitePaper Submission Example.

After the step 1, I start share and repository. And all starts fine.

I went to http://localhost:8081/share -> start workflow then selected publich Whitepaper to Web workflow.

When I clicked on "Start Workflow" button, I get "01260009 Failed to start workflow activiti$publishWhitepaper"

The log says:

16:31:49,149 WARN [org.activiti.engine.impl.bpmn.behavior.ScriptTaskActivityBehavior] Exception while executing scripttask1 : couldn't find a variable type that is able to serialize [object global]
16:31:49,149 DEBUG [org.alfresco.repo.jscript.ScriptLogger] org.alfresco.service.cmr.workflow.WorkflowException: 01260010 Failed to start workflow activiti$publishWhitepaper:1:404.
16:31:49,164 DEBUG [org.alfresco.repo.jscript.ScriptLogger] Returning 500 status code

It complains about scripttask1 which is as below:

    <scriptTask id="scripttask1" name="Submit" scriptFormat="javascript" activiti:autoStoreVariables="true">
      <script><![CDATA[var scwf_approveCount = 0; var scwf_tpApproved = false;]]></script>
    </scriptTask>

Can someone let me know what I am missing, please?
I am using Tomcat 7.0.37 and JDK 1.7

Thanks in advance.
Sean

I guess you did a mistake in your javascript code. Please attach code that is executed while workflow starting and stack trace.

Hello,

I'm new to Alfresco and started to rebuild and understand the Workflow mechanism in Alfresco. I used therefore the "https://github.com/jpotts/alfresco-developer-series/tree/master/workflow" tutorial. Everything works fine until I'll step into the publishWhitepaper.bpmn example.

I tried to recreate the example with the source code of Jeff Potts. But I end up at this point again. Maybe I'll missed something.

At the execution of


<scriptTask id="scripttask1" name="Submit" scriptFormat="javascript" activiti:autoStoreVariables="true">
      <script>execution.setVariable('scwf_approveCount', 0); execution.setVariable('scwf_tpApproved', false);</script>
    </scriptTask>
‍‍‍‍‍

it fails with the log:
INFORMATION: Starting ProtocolHandler ["http-bio-8080"]
2015-05-26 08:44:05,374 WARN [bpmn.behavior.ScriptTaskActivityBehavior] [http-bio-8080-exec-3] Exception while executing scripttask1 : couldn't find a variabl
e type that is able to serialize [object global]

Now I hope, there is somebody who could help me to understand the failure within this javascript code.

I usede Alfresco in the Version


<alfresco.version>5.0.d</alfresco.version>

The javascript code is fine, but before of the script task, the variable scwf_approveCount or scwf_tpApproved is not defined or initialized.

I don't know why your workflow not start. May be you don't have a form assigned to the start task, in this case, add a "bpm:startTask" form or other form:


<startEvent id="start" name="Start" activiti:formKey="bpm:startTask"></startEvent>

Greetings,

Hi! There is a form assigned in a tutorial:


<startEvent id="startevent1" name="Start" activiti:formKey="scwf:submitReviewTask"></startEvent>
‍‍‍

but It really won't start neither in javascript language nor after changing to groovy…

It just doesn't work….

( btw, the message the same as mentioned above:
2015-10-03 18:55:18,824 WARN [bpmn.behavior.ScriptTaskActivityBehavior] [http-bio-8080-exec-7] Exception while executing scripttask1 : couldn't find a variable type that is able to serialize [object global]
2015-10-03 18:55:18,829 DEBUG [repo.jscript.ScriptLogger] [http-bio-8080-exec-7] org.alfresco.service.cmr.workflow.WorkflowException: 09030008 Failed to start workflow activiti$publishWhitepaper:1:607.
).

Any clue ?

Hi! Have you found the solution ? I have the very same problem….

I just discover that the error of the type:

Failed to start workflow activiti$***:1:404.

could append if the script in the fisrt task of a workflow is in error.

In my case the fisrt task add a script of the type ScriptTaskListener with the property event="create", and this script add a typo, whitch result in this error message.
