Re: How to pass a parameter to an ASO constructor?

[Danny Mandel]

Ping? Short story is that I'm attempting to pass a constructor argument 
(in this case, the boolean false) when creating my ASO.

I've continued searching for this and am still stuck.  The closest thing 
I found on the wiki and attempted to adapt to my needs was this:

   <contribution configuration-id="tapestry.state.ApplicationObjects">
       <state-object name="isToolTryout" scope="session">
           <invoke-factory object="service:BooleanFactory"/>
       </state-object>
   </contribution>

   <service-point id="BooleanFactory" 
interface="org.apache.tapestry.engine.state.StateObjectFactory">
       <invoke-factory>
           <construct class="java.lang.Boolean">
               <boolean>false</boolean>
           </construct>
       </invoke-factory>
   </service-point>

Which results in the following error when attempting to access the ASO 
for the first time:

---------
Unable to construct service org.tolweb.tapestry.BooleanFactory: Instance 
factory for service org.tolweb.tapestry.BooleanFactory returned false 
which does not implement the 
org.apache.tapestry.engine.state.StateObjectFactory interface declared 
by the extension point.
---------

I'll happily write up a howto on the wiki if anyone can provide insight 
to help this work.

Thanks,
Danny
Hi all,

I'm trying to figure out how to pass a constructor argument when 
constructing an ASO.  I have a java.lang.Boolean, and it *needs* to 
have a parameter passed in the constructor (no empty-arg constructor 
exists).  I know this ought to be simple, but I don't see any 
documentation explaining the proper way to do this.  This current way 
doesn't work:

       <state-object name="isToolTryout" scope="session">
           <invoke-factory service-id="hivemind.BuilderFactory">
               <construct class="java.lang.Boolean">
                   <boolean>false</boolean>
               </construct>
           </invoke-factory>
       </state-object>

Any hints would be greatly appreciated.

Thanks,
Danny
