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.
