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

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
