TaskState after sending redirect

Question

Hi all

i have a sample process like this: alt text In there i have a ivy task, after i close user dialog, i want to redirect to another start process by using HttpResponse (not use endpage element). With some small investigation i see the task state after i send redirect still be RESUMED,

If i change this process to continue with endProcess element (after script httpRedirect), it throw exception:

java.lang.IllegalStateException: Cannot call sendRedirect() after the response has been committed
    at org.apache.catalina.connector.ResponseFacade.sendRedirect(ResponseFacade.java:494)

    at ch.ivyteam.ivy.bpm.engine.internal.BpmEngine.handleNormalRequest(BpmEngine.java:191)

So, to deal with this case, i need to reset task manually?

To redirect a user to another page at the end of a process, the End Page element is your choice. It will End the task (and the Case) and redirects to linked page. The linked page can be a JSP page and in this JSP page you can forward/redirect to the desired destination.

can we make a dynamic redirecting on jsp page? depending on condition i can navigate to different pages. that's why i want to use java code to redirect instead of endpage
