pageflow + backbuttoning

[miron]

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?

[miron]

my pageflow looks like this...

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

<pageflow-definition
        xmlns="http://jboss.com/products/seam/pageflow"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://jboss.com/products/seam/pageflow 
                            http://jboss.com/products/seam/pageflow-2.0.xsd"
          name="pageflow_home">

     <start-page name="overview" view-id="/app/overview.xhtml" back="enabled" redirect="true">
          <transition name="data_request" to="data_requested_already"></transition>
          <transition name="org_unit_list" to="org_unit_list_submitted_already"></transition>
          <transition name="assignment" to="assign">
               <action expression="#{assign.init}"/>
          </transition>
          <transition name="output" to="output">
               <action expression="#{output.init}"/>
          </transition>
     </start-page>

     <page name="data_request" view-id="/app/dataRequest.xhtml" back="enabled" redirect="true">
          <transition to="overview" name="overview">

          </transition>
     </page>
     <page name="data_import" view-id="/app/dataImport.xhtml" back="enabled" redirect="true">
          <transition to="data_import_ok" name="data_import_ok">
               <action expression="#{dataImport.dataImport}"/>
          </transition>
          <transition to="overview" name="overview"></transition>
     </page>
     ...
     
</pageflow-definition>

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

http://docs.jboss.com/seam/2.0.1.GA/reference/en/html/jbpm.html#d0e5432

[miron]

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

[miron]

Is there really nobody with expirience with pageflows?
