Description

From the mailing list:

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.
