It looks like I can reproduce this issue easily. For instance say I
have a page that contains:
@InjectState("visit")
public abstract Visit getVisitObj();
And have the exact same getter (annotation or not) in my component:
public abstract Visit getVisitObj();
The binding exception seems to occur.
Does this seem like correct behavior for tapestry? I do this quite
often in my components because at times the page may not have the
visit or some other object that the page has, but other times it may.
Thoughts and help greatly appreciated
