Oh I see! thanks !!
My BreadCrumbs class needs to be an ASO which is needed by the
navigation component, it also requires ComponentResources. I was
injecting them (using @Inject and @ApplicationState)
So instead I should use InjectService("ComponentResources") in the
BreadCrumbsImpl constructor and then Navigation should implement
BreadCrumbs. But I'm not sure how to create the service as an ASO in
AppModule, perhaps:
@Inject
private ComponentResources resources_;
public void contributeApplicationStateManager(
MappedConfiguration<Class, ApplicationStateContribution>
configuration) {
ApplicationStateCreator<BreadCrumbs> creator = new
ApplicationStateCreator<BreadCrumbs>() {
public BreadCrumbs create() {
return new BreadCrumbs(resources_);
}
};
configuration.add(BreadCrumbs.class, new
ApplicationStateContribution(
"session", creator));
}
Thanks again,
Peter

Basically, you shouldn't mix component classes with services classes. When
you do so, you need to define an interface for your components to implement.

Hi All
I use Tapestry 5, Java 6 with the maven plugin in eclipse 3.3. I am
building a user specific navigation component, and I am getting this
strange error:
java.lang.LinkageError
loader constraint violation: when resolving method
"com.web.services.BreadCrumbs.getRootLink()Lcom/web/components/IrmLink;"
the class loader (instance of
org/apache/tapestry/internal/services/ComponentInstantiatorSourceImpl$PackageAwareLoader)
of the current class, com/web/components/Navigation, and the class
loader (instance of org/mortbay/jetty/webapp/WebAppClassLoader) for
resolved class, com/web/services/BreadCrumbs, have different Class
objects for the type com/web/components/IrmLink used in the signature
I have tried to clean the project several times thinking this is an
issue with cached resources on the classpath, but have had no luck, so I
am starting to wonder if this could relate to Java 6 and the maven plugin.
Has anyone seen this before?
thanks for your help.
Peter
