Tapestry 4: Application State Objects

Wed, 29 Jun 2005 13:02:04 -0700

I am trying to setup a Visit and Global object the new Tapestry 4 way with Application Stae Objects. I can get one or the other to work but not both together. If I attempt to use 2 Application State Objects I get the following exception:
Error: Method 'public abstract com.scottwalter.sandbox.tapestry4.Global com.scottwalter.sandbox.tapestry4.pages.Home.getGlobal()' (declared in class com.scottwalter.sandbox.tapestry4.pages.Home) has no implementation in class com.scottwalter.sandbox.tapestry4.pages.Home (or enhanced subclass $Home_0). 


Below are 2 different ways I tried to setup my hivemodule.xml file with 
both getting the same error:


1.
<?xml version="1.0"?>


<module id="tapestry4sandbox" version="1.0.0" 
package="com.scottwalter.sandbox.tapestry4">


   <contribution configuration-id="tapestry.state.ApplicationObjects">
     <state-object name="visit" scope="session">
       <create-instance class="com.scottwalter.sandbox.tapestry4.Visit"/>

     </state-object>  
   </contribution>
  
   <contribution configuration-id="tapestry.state.ApplicationObjects">

     <state-object name="global" scope="application">
       <create-instance class="com.scottwalter.sandbox.tapestry4.Global"/>

     </state-object> 
   </contribution>   
</module>



2. 
<?xml version="1.0"?>



<module id="tapestry4sandbox" version="1.0.0" 
package="com.scottwalter.sandbox.tapestry4">  
   <contribution configuration-id="tapestry.state.ApplicationObjects">

     <state-object name="global" scope="application">
       <create-instance class="com.scottwalter.sandbox.tapestry4.Global"/>

     </state-object> 
     <state-object name="visit" scope="session">

       <create-instance class="com.scottwalter.sandbox.tapestry4.Visit"/>

     </state-object>      
   </contribution>   
</module>


Here is a snuppet from my page that I am trying to inject state into:

   @InjectState("visit")
   public abstract Visit getVisit();

  
   @InjectState("global")
   public abstract Global getGlobal();   

Do I just have something in my hivemodule.xml file wrong?  Like I said 
above, I can get one or the other to work but no both


thanks, scott.
