Tapestry 4 Adding a new EngineService

Hi,
I'm attempting to add a new Engine Service to Tapestry 4,  
cannibalised from ChartService to do something vaguely similar, but  
I'm getting:

The value obtained using locator 'engine- 
service:dynimage' (<OuterProxy for engine service 'dynimage'>) is not  
compatible with the existing property (of type  
com.azudio.project1.DynImageService).

What does this mean exactly?

In my hivemodule.xml

     <service-point id="DynImageService"  
interface="com.azudio.project1.DynImageService">
         <invoke-factory>
             <construct class="com.azudio.project1.DynImageService">
                 <set-service property="builder" service- 
id="tapestry.request.AbsoluteURLBuilder" />
                 <set-service property="request" service- 
id="tapestry.globals.HttpServletRequest" />
                 <set-service property="response" service- 
id="tapestry.globals.HttpServletResponse" />
                 <set-object property="servletPath" value="app- 
property:org.apache.tapestry.servlet-path" />
                 <set-object property="linkFactory"  
value="infrastructure:linkFactory" />
             </construct>
         </invoke-factory>
     </service-point>

     <contribution configuration- 
id="tapestry.services.ApplicationServices">
         <service name="dynimage" object="service:DynImageService" />
     </contribution>

I've got a component DynImage that has the DynImageService injected  
into it:

     public abstract class DynImage extends BaseComponent {

         // Component Params
         public abstract IAsset getAsset();
         public abstract int getSize();

         // Component property
         public abstract String getUrl();
         public abstract void setUrl(String url);

         @InjectObject ("engine-service:dynimage")
         public abstract DynImageService getDynImageService();

         String assetUrl = getAsset().buildURL(cycle);

         ILink link = getDynImageService().getLink(cycle,false,new  
Object[]{assetUrl,getSize()});

         setString(link.getURL());

     }


Any ideas? is this enough info?
Thanks,

Adam

Paul,

Nope, my hivemodule.xml looks ok, no spaces after the hyphen, its  
just where gmane has put in line breaks.

I am not sure of the solution to your problem but a quick observation is 
that every "-" has a space after it e.g. "service- id" this does not seem 
right.

Hope this helps

Paul
