Error with passing false in property expressions
------------------------------------------------

                 Key: TAP5-663
                 URL: https://issues.apache.org/jira/browse/TAP5-663
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.1.0.3
            Reporter: Andy Blower
            Priority: Minor


I just tried out the new T5.1 property expressions for the first time and got an error. I'm trying to replace this:

${linkTitle}

public String getLinkTitle() {
	return getTitle(false);
}	

With this:

${getTitle(false)}


Which I should be able to do according to the Grammar as far as I can see, since but I get this error when I try it:


Caused by: org.apache.tapestry5.internal.services.PropertyExpressionException: Node false (within expression 'getTitle(false)') was type FALSE, but was expected to be (one of) DECIMAL, DEREF, IDENTIFIER, INTEGER, INVOKE, LIST, SAFEDEREF, STRING.
