Hello Flavio,

Thanks for your help, so I post the solution for others here.

in our HTML Dialog we trigger the process start with our ProcessStarter and pass the TaskId to start as parameter
The process retrieves the task start url with [out.redirectUrl = ivy.html.taskstartref(in.task);]
At the end of the process there is an End Page that points to a "redirect-end-page.jsp" using this redirectUrl for redirecting the user automatically to the Task. (document.location.href='<%=redirectTask%>')

Thanks again Flavio!

Emmanuel

@Emmanuel: Why you can't use an End-Page for the redirect? The End Page does end the current running process and task properly. With a redirect in the middle of a process, the process is interrupted unexpected which (could) cause in unexpected behaviour/errors.

Hello Flavio,

Sorry for that long and not very "understandable" question ;) To make it short: is there a way to start a Task programmatically in such a situation: 1. The User clicks on a Displayed Task (HTML Dialog - JSF). 2. This triggers a Process Start dynamically, which gets as parameter the selected TaskId. 3. In this process we can find the Task with the TaskId and we would like to start it and display it to the user. As the Task is started in a Process that is not part of the HTML-JSF Dialog Logic, using "redirect" techniques described in the question do not work. Any Idea?

Cheers

Hello Emmanuel, could you describe your use case? Basically I would suggest to use an End Page to forward a workflow/client to the next process.
