Description

As posted in Tapestry mailing list:

I have been unable to write a test to reproduce the error since it happens randomly which makes me thing that it happens when classes are enhanced. I have checked all my classes and com.estudiowebs.CMS.components.AbstractCMSComponent is the only place where that property is declared.

Here is my code:

public abstract class AbstractCMSComponent extends BaseComponent

{ @InjectPage("News") public abstract News getNewsPage(); }

public abstract class AbstractCategoryLinker extends AbstractCMSComponent {

public IPage onClickMenuItem() {
Contact cp = getContactPage();
return cp;
}

public abstract class MenuNavigation extends AbstractCategoryLinker {

}

Here is the stack trace:

org.apache.hivemind.ApplicationRuntimeException
Property newsPage has already been accounted for by the element at Annotation @org.apache.tapestry.annotations.InjectPage(value=News) of public abstract com.estudiowebs.CMS.pages.News com.estudiowebs.CMS.components.AbstractCMSComponent.getNewsPage().
location: Annotation @org.apache.tapestry.annotations.InjectPage(value=News) of public abstract com.estudiowebs.CMS.pages.News com.estudiowebs.CMS.components.AbstractCMSComponent.getNewsPage()
