I'm new to JBPMN workflow model and I have requirement where I shall be getting a confirm message box asking for YES(to continue) or NO(to stay in the same form) in the workflow form upon clicking the "Submit" button.So kindly anyone suggest me the way how to give that extra functionality to "Submit" button in workflow form.
Which interface you are using Alfresco Share or explorer? This is something which you need to do on client side. For alfresco explorer changes in manage-task dialog related jsp and in alfresco share change workflow task related ftl and javascript file which intercept the submit event and show popup on click of ok final request will be submitted and normal flow continue.
