Query regarding using the Alfresco amp alfresco_http_activiti_client for triggering the APS processes

[paiyyavj13]

Hi,

I am trying to use the amp: alfresco_http_activiti_client available in the git link: GitHub - rjmfernandes/alfresco_http_activiti_client , for triggering an Alfresco Process Services workflow from ACS via a script triggered by a rule.

I am using ACS 5.2, APS 1.6.2 Enterprise versions.

Below is my javascript which uses the "activiti" Root object from the above module:

//test script for http_activiti_client

var obj=eval('({"name":"test process"})');
activiti.startProcess("CustomAdhoc","Custom Adhoc Test Process",obj);

where: CustomAdhoc is my APS process name.

I am testing the module so I am not attaching the document and calling the startDocumentProcess method, instead am calling the startProcess method.

The error I get in logs is NullPointerException, I debugged and I believe that the ACS application is not able to search and retrieve the ProcessDefinition with the processName supplied, in my case: CustomAdhoc.

Is there any config change that is needed on APS ? Any pointers would help... Thank you...

I debugged and found out the issue and was able to call APS processes through ACS using root objects from the mentioned amp.

It worked when I supplied the document and document field properties to the startDocumentProcess method.

Earlier was trying to trigger a sample process without any document by calling the startProcess method, but could not- as the code did not have checks for document and document field properties being null.

Hi all, The readme says: “After applying the amp you need to set some configuration on the alfrescop-global.properties file”, but where is the amp file?

[paiyyavj13]

if you build the project, you will see the amp file created in the target folder.

Please refer to this article for the steps to trigger an already modelled and deployed APS workflow/process from ACS.
