workflow details failure on Share

[jeremiebal]

Hi

I would test a workflow.

In this one, there is a userTask not assigned and a timer event wich fire a service task.
After this one, there is another user task assigned to a GROUP and after the end Task.

So, the workflow works but if i want to see workflow details on Share i have a Failure error like you can see on the image.

I don't understand why.

So please, if someone can tell me where is my error, i thanks him a lot.

Hi,

Your workflow structure is weird. You cannot approve it until you retrieved your confirmation email.
I would have expected something more like that:
http://jmuras.com/blog/wp-content/uploads/2014/01/EmailRemindersWorkflow.png

The workflow details page tries to generate a graphical visualisation of the workflow, and this unusual structure might be what throws Alfresco off.
Could you attach your logs please?

Hi Scouil

In fact, i would like to get the instance ID of my workflow when it start. But if i make a script in a service Task after the start Task or in a TaskListener of my first UserTask, the Instance id is null.
So the only solution that i found is to write a usertask not assigned with a timer event wich fire a serviceTask wich it get the instance Id. And it works.
And after the serviceTask, there is a flow to the real first userTask ( a review task).

To explain more clearly, you can find my codes : that wich works for the workflow-details and that wich not.


And this is my log :

I would like to get the instance Id of a workflow inside it when it just to start but this is the only thing that i could do.

Thanks a lot

[jeremiebal]

I have resolved my problem

I can get instance ID and first user task id inside my workflow with this code.
And the workflow-details works ! 🙂
