Re: Tapernate-Example HiveMindAutowireWorker Problem

Chris,

In my page class, I have the following abstract methods:

   public abstract Contact getContact();
   public abstract void setContact(Contact contact);

   public abstract String getConfirmPassword();
   public abstract void setConfirmPassword(String confirmPassword);

   public abstract String getErrorMessage();
   public abstract void setErrorMessage(String message);

   public abstract ContactDAO getContactDAO();

   @InjectPage("RegistrationSuccess")
   public abstract RegistrationSuccess getRegistrationSuccess();
While comparing my class with the methods in the EditMessage.java class, both seem to follow the same pattern. One strange thing about it is that all pages are having the same problem, even those with very simple page classes and do not have abstract methods. When I remove the auto-wiring XML fragment from the hivemodule.xml file, everything seems to be normal (excepted that the coded that depend on the auto-wiring is no longer working).
I tried what Mark suggested without much success and cannot confirm what Mark has reported. 

As always, thanks for your help!

Hmmmm.  That's weird.  But, thanks for the tip.  I've submitted the code as
a patch to Tapestry.  So, I need to figure out how to get it working.  So,
what you're saying is that if the auto-wiring stuff is inside a jar file and
not part of your application's hivemodule.xml file, then it bombs?

I had that very same problem when I tried to package the Tapernate
auto-wiring stuff in a drop-in jar. It said that one of the parameters of
the Shell component has already been claimed by a different enhancement
worker.

When I just put the service definition and configuration contribution into
my application's "root" module descriptor everything works fine.

Hi All,
I am using Tapernate and HiveMindAutowireWorker and HiveMindAutowireWorkerFactory from the Tapernate example in my applicaiton. The XML in my hivemind.xml file and the auto-wire classes are taken from the Tapernate example: 

    <service-point id="AutowireWorkerFactory"
            interface="org.apache.hivemind.ServiceImplementationFactory"
            parameters-occurs="none">
        <invoke-factory>
<construct class="org.apache.tapestry.enhance.HiveMindAutowireWorkerFactory" /> 
        </invoke-factory>
    </service-point>
<service-point id="AutowireWorker" interface="org.apache.tapestry.enhance.EnhancementWorker"> 
        <invoke-factory service-id="AutowireWorkerFactory" />
    </service-point>

    <contribution configuration-id="tapestry.enhance.EnhancementWorkers">
        <command before="tapestry.enhance.abstract-property"
            after="tapestry.enhance.dispatch-inject"
            id="inject-autowire" object="service:AutowireWorker" />
    </contribution>
This is working as expected when there is no exception. But when the application throws any exception, it is causing the following exception in the log file. Has anyone encounter this problem? 

Thanks!
Tat
