----------------------------------------
Hey Howard,
Thank much for correcting my attempt to guess what's under the covers. And
thanks for the fix. I'll try it...
OK, that was easy and, yup, it worked.

> Leaky Framework: cannot implement a method named 'getServlerContext()' on a

> I've got a page that's working fine. Was getting the ServletContext via an
> injected ApplicationGlobals and using the ApplicationGlobals within methods
> that needed the ServletContext. Started to be a few methods needed it so I
> created a simple convenience method:
> @Inject
> @Service("ApplicationGlobals")
> private ApplicationGlobals applicationGlobals;
> protected ServletContext getServletContextObj() {
> return (applicationGlobals == null ? null :
> applicationGlobals.getServletContext());
> }
> And:

> Turns out that getServletContext() is "reserved" by Tapestry. I tried
> protected abstract ServletContext getServletContext();
> But no dice.
> Work-around: changed the name of the method. That worked. Downside: the
> getServletContext() method name is the obvious /desirable one.
> Suggestion: Prefer to have Tapestry not take over method names. If it must,
> prefer to give them scoped names that aren't likely to be used by regular
> apps. E.g., get/setTap5Foo (in general) and getTap5ServletContext() (in
> particular).
> Thanks.
