Pageflow recurence
blabno Jan 23, 2008 4:18 PMI have following pages :
1)/locations/browseLocations.jspx
2)/locations/addCountry.jspx
3)/locations/complete.jspx
I want to add country to DB. So I place button on browseLocations.jspx :
<s:button value="Add" view="/locations/addCountry.jspx"/>
Now the page flow should start. But when there is a problem during countryCreator.addCountry method invocation, then I want to stay on addCountry.jspx but if I write transition to /locations/addCountry.jspx then I get Exception :
ERROR [SeamPhaseListener] uncaught exception java.lang.IllegalStateException: begin() called from long-running conversation, try join=true
addCountry.jpdl.xml
<?xml version="1.0"?> <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="addCountry"> <start-page name="addCountry" view-id="/locations/addCountry.jspx"> <redirect/> <transition name="next" to="evaluateSuccess"> <action expression="#{countryCreator.addCountry}" /> </transition> <transition name="cancel" to="cancel"/> </start-page> <decision name="evaluateSuccess" expression="#{countryCreator.error}"> <transition name="false" to="complete"/> <transition name="true" to="addCountry"/> </decision> <page name="complete" view-id="/locations/complete.jspx" no-conversation-view-id="/locations/browseLocations.jspx"> <redirect/> </page> <page name="cancel" view-id="/locations/browseLocations.jspx"> <end-conversation before-redirect="true"/> <redirect/> </page> </pageflow-definition>
pages.xml
<pages> <page view-id="/locations/addCountry.jspx"> <begin-conversation pageflow="addCountry"/> </page> </pages>
Now, if I cut out everything from pages.xml then there is no conversation at all, and I cannot add anything, nor can display FacesMessages.
Is there other solution than introducing <start-state> and inserting method annotated with @Begin(pageflow="addCountry") in countryCreator bean ?
