Double Review Workflow

irenailievska

I am trying to create custom workflow that will be double approve and reject process. The diagram is included in attachment. How can I do this? I have some small understanding of how workflows in alfresco work, but not nearly enough. I want to be able when the workflow is supposed to go in Approve, to give the user that approved the task last (because that is how alfresco review task works - Approved is reached only when the number of approved is enough) another form where he will be able to choose the next people that are supposed to be the second approve/reject level. If anyone has any idea that would help solve this problem I would be very happy

. Any Idea will be accepted with open arms.

Thanks in advance,
Irena

Is this even possible? Any Ideas ?

I solved it - the final image of the diagram is in the attachment. The code for the workflow is below

In order to see the Approve and Reject buttons in share-config-custom.xml you only need to change the transitions property with your property (exwf:reviewOutcome)


 <field id="exwf:reviewOutcome" set="response" >
       <control template="/org/alfresco/components/form/controls/workflow/activiti-transitions.ftl" />
 </field>

‍‍‍‍‍‍‍

You need to register the workflow and the content model and that is it.
