Launching a workflow within a workflow using javascript

[buje85]

Hi,

I want to launch a workflow from within another workflow.

I have this code that will create a workflow correctly if I run it through the javascript console addin.

   var doc = userhome.createFile("testing1.txt");
   doc.content = "original text";   

   
   var workflow = actions.create("start-workflow");
       workflow.parameters.workflowName = "activiti$ps_New_Post_Workflow";
       workflow.parameters["bpm:workflowDescription"] = "Please index test" ;

       workflow.execute(doc);
‍‍‍‍‍‍‍‍‍‍‍

If put the code into my activiti:taskListener on the workflow I get an error "failed to execute supplied script : null"

It seems to fail on the workflow.execute(doc) line.

Does anyone know what I am doing wrong, Is it not possible to launch a workflow from within a workflow? Perhaps there is a better way to do this.

Thanks,

It seems something is null,please paste your alfresco.log here.
I haven't ever launched a workflow within a workflow,can't you use activiti Sub-Process as instead?
And you'd better not use "workflow" as variable name,there is a root object named "workflow" in alfresco

I have found this post which seems to suggest it is a problem with a new release of activiti - https://forums.alfresco.com/forum/developer-discussions/workflow/problem-start-workflow-script-writt...

I have tried using the code in that post and get the same issue, also my code runs fine from the javascript console. I have also tried my code using different variable names as I know some are already root objects like you suggested.

I haven't tried the sub process. Our workflow processes can be quite long so I want to split the process up into 3 smaller workflows to make things simpler I actually want the code to run at the very end of the workflow to start the next one. I am not sure if a sub process is the right idea for that. Is there another way that may you think I should try?


Thanks,

It might be a bug of your activiti version ,can you download a newer alfresco version (for example 5.0 which will use activiti 5.16) and test whether it works ?
