Workflow  Share Form Issue

Question asked by tarun27in on Oct 28, 2013
Latest reply on Jul 16, 2015 by stacy
Hi,

I am trying to build a custom workflow in alfresco community edition. Basically I am trying to modify the existing workflow called lifecycleprocess. I have been able to deploy the process using workflow console without error. But I am not able to do any change at all on the workflow form. My workflow is called leaveprocess and I have the following code :-

I am unable to understand, no matter what changes I do in this code for share-workflow-form-config.xml, It does not reflect when go to Share->Workflows I've started->select Leave Process. It always show the default form there. Somebody please guide me what I am doing wrong here.

Thanks in advance.

Tarun
