I want to start usertask task2 after catching intermediate signal. It should display a user input form, proceed with its task listener and then proceed to service2. When I am catching signal, task listener is called. But I need to have user input form first. Can someone tel me how to implement this OR see my code as an attachment and help me resolving this issue.
What do you mean with "I need to have user input form first". You want to execute specific logic when a user opens the user task form? That's not something that's provided with Activiti, you should implement that yourself in your task form application. Or trigger a signal or message event from there.
