    Problem on closing bpm task form from custom worklist application

      Hi all,

      following some material i found on the web, mainly these two articles:


      I successed in realizing a traditional Fusion Web App able to remotely open BPM human task forms in an inline-frame (or pop-up or whatever...).
      Anyway, i'm encountering the following problem: whenever i close any of the task forms approving or rejecting the task, the task is pushed forward in the BPM process, but the task form remains opened in the browser and i get the following error:

      Caused By: java.lang.NullPointerException
      at oracle.bpel.services.workflow.worklist.adf.ADFWorklistBeanUtil.getURLTORedirect(ADFWorklistBeanUtil.java:416)
      at oracle.bpel.services.workflow.worklist.adf.InvokeActionBean.getParentURL(InvokeActionBean.java:1048)
      at oracle.bpel.services.workflow.worklist.adf.InvokeActionBean.invokeScript(InvokeActionBean.java:1063)

      By investigating the matter, i discovered the problem was i didn't provide the "parentURL" parameter to the task flow in the hash map passed to the getTaskDisplayURL method, but even if i provide that parameter the human task form doesn't close itself which is quite annoying. I even tried to pass the "bpmBrowserWindowStatus" parameter with value "close" or "keep", and in that case i get no error but the browser shows an error pop-up with no message and the task form keeps to stay open: arrrrrghhh!!!
      Does anybody has any clue on this behavior?

      Thanks in advance,

          I don't know if you already found solution for your problem, but recently I've found note on metalink: 1364437.1

          Solution (Workaround)
          +1. In your application, locate and open the <HumanTaskName>_TaskFlow.xml file.+

          +2. Remove/comment the finalizer method binding as follows+
          +<!-- <finalizer id="__111">#{invokeActionBean.invokeScript}</finalizer> .... -->+

          +3. Redeploy the human task and test.+

            Hi Fabio,

            I saw your post and see that you have worked on something similar to my problem.

            I have created an ADF application for human task and integrated manually. I could trigger my UI form BPEL human task but when i invoke any action, it is going to 404 page not found error.

            When i verified the URL, i could see the parentURL mentioned in the parameter list to task flow. Could you please shed some light on this?

            Thanks in advance for the help
