Description

As posted in the tapestry forums:

At first I thought I could work around these issues but they seem to
be popping up more and more throughout my application. Its really
becoming an issue for me.

Ever since I have moved from .page and .jwc files to annotations I get
these exceptions more often.

I don't believe I am doing anything wrong with these annotations. As
you can see by the following one I have just declared a DelegateBean
in my class. Using

@Bean(SimpleValidationDeleage)
public abstract SimpleValidationDelegate getDelegate();

That same Delegate is used on mulitple pages and in components. From
what I understand this should be acceptable.

This issue also has sprung up on my declaring the same Persistent
property on different pages or components using the @Persist
annotation.

I've also recieved a similar exception doing the following in which both the
page and component contain:
@InjectState("visit")
public abstract void getVisitObj();

I was able to work around the issue by changing the component to be
@InjectState("visit")
public abstract void getVisitObjComp();

I didn't run into these problems before I used annotations. I'd also
hate to have to go back to .page and .jwc files since there are so
many files that I've changed.

Here is an one of the exceptions:
