    pageflow + backbuttoning

    jan fryscak Newbie

      hi all,
      I'm using jPDL pageflow and have a problem with backbuttoning, I've got Illegal navigation warning after backbuttoning in browser and clicking any link...I've searched the web and added attribute back=enabled to any page in pageflow.xml...but it doesn't work :( I've found in class Pageflow method validatePageflow this code:


      boolean canReposition = getPage().isBackEnabled() && getSubProcessInstance().getProcessDefinition().getName().equals(pageflowName) && pageflowNodeName!=null; 
      


      pageflowNodeName is always null, so canReposition is never true...


      any idea?
      thanks miron

          Can you post a copy of one of your page flows?

            my pageflow looks like this...


            <?xml version="1.0" encoding="UTF-8"?>

              How are you starting the pageflow?  @Begin, @BeginTask or @StartTask or with a begin-conversation element with a pageflow attribute?

                with begin-conversation in pages.xml


                    <page view-id="/app/overview.xhtml" login-required="true" no-conversation-view-id="/app/overview.xhtml">
                         <begin-conversation join="true" pageflow="pageflow_home"/>
                    </page>

                  Unfortunately, I have no experience with pageflows. 


                  However, the topic SeamJPDLBeginningAPageflow does reference doing joins on begin conversation and the response from Gavin.

                    Thanks for your reply, but it isn't my case...pageflow is started,- it produces the Illegal navigation warning
