It seems there is something wrong with your activiti definition .
Please check the exception stack trace, there should be a detail message telling you what property is unknown

You can try to add following code under extensionElements sub element of managerapproval to your activiti definition
<activiti:taskListener event="complete" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">
<activiti:field name="script">
<activiti:string>
execution.setVariable('status', task.getVariable('status'));
</activiti:string>
</activiti:field>
</activiti:taskListener>

Hi,

Thanks,now the exception is gone.But it is giving one more exception saying "org.activiti.engine.ActivitiException: No outgoing sequence flow of the exclusive gateway 'sid-EA621276-097A-47E9-8B70-8EF3C218150B' could be selected for continuing the process".Can you please advice on this.

It seems the status value is null and the gateway is not able to choose the correct path.
You can try to bind status formProperty to status variable like this

<activiti:formProperty id="status" name="Status" type="enum" variable="status" readable="true" writable="true">

No luck,still getting same exception.

"org.activiti.engine.ActivitiException: No outgoing sequence flow of the exclusive gateway 'sid-EA621276-097A-47E9-8B70-8EF3C218150B' could be selected for continuing the process"

Can you please validate your process definition file ? And one more thing can you please try to print value of status ?

I think Kayne is right. Probably status value is null and it is not able to find out any path through exclusive gateway.

I will suggest to try with default flow once so that you can conclude that it is having issue with value of status variable.

Getting Activiti explorer and Alfresco playing on the same data is tricky. It is very easy to seriously mess up unless you have a solid understanding and know exactly where and how to tweak.
