Hi all,

I'm working on a workflow and have find some problems to make it work properly.

It works fine, but when I try to show the approval percentage in the workflow details it always displays 0 (zero).

Here is my code:

customworkflowmodel.xml:

The field testwf:currentPercent in workflow-details always returns 0. But it does show the real value in the activiti console… ¿any ideas?

Thank you very much in advance!!

Hello,

after the initial start task has been completed (which is usually immediately when the workflow is started), you can't update its properties further via standard APIs. Since your actual percentage value will be based on a dynamic state, I'd advise you not to use properties and instead use a form filter / field processor on the Repository tier to generate a transient field percentage.

Regards
Axel

Hi Axel,

Finally I found it out and tried some other way to show the progress, changing the node properties. Thank you anyway Smiley Happy
