> I have my own OGNL property accessor to handle nulls in my object graph. But
> I have some logic in it, which needs to know if the root ognl operation was a
> set/get.
> OGNL provides a feature called "traceEvaluations" in which we call
> "setTraceEvaluations(true)" on the OgnlContext and the property accessor is
> provided with the evaluation. Using this evaaluation, it is possible to find
> if the root ognl operation was a set/get.
> Tapestry creates the OgnlContext in the
> org.apache.tapestry.services.impl.ExpressionEvaluatorImpl.createContext()
> method. As it is currently private, I had no choice but to duplicate the
> class source in my own class, add the required line and replace it as the
> implementation of the ExpressionEvaluator service.
> It would be good if it is made protected/public. Then I can subclass it /
> intercept the createContext() method and do my stuff.
