Pedro Santos updated WICKET-4008:
---------------------------------

    Attachment: WICKET-4004.patch

Attaching an initial implementation.

- reports user with meaningful exception messages
- removes string manipulation code from PropertyResolver

@devs, I implemented the recursive descent parser and the  EBNF grammar is at 
PropertyExpressionParser javadoc. Is the implementation OK? All tests are 
passing, but I will write some more next.

> Improve PropertyResolver to use a parser
