if i use this: <param name="expression">title.length()</param>
i get a message saying 'Got result of N when trying to get boolean' where N is the length.
however, if I use a simple OGNL expression: <param name="expression">title.length() == 10</param>
i get nothing. no error, no output, regardless of what input i pass.

Try title.length() > 10
The expression validator is a little confusing at the moment, if the expression is FALSE, it is invalid.

i tried escaping the <, but still get no validation on length - am i accessing the method correctly?

Toby,
Because it's XML, you need to escape the < - ie <

hi there again, i am attempting to validate string length using XWork validation.
i solved the problem using a custom validator, which i have attached in case anyone finds it useful ... feel free to roll it into xwork.
then i suddenly realised that i could possibly use the expression validator to test string length without having a custom class. so i wrote the following, but it doesn't parse because of the '<' character (this possibly means that the example on the wiki is also broken). wrapping in a CDATA element gives an error stating 'Got result of null when trying to get boolean'.
<validator type="expression"> <param name="expression">title.length < 10</param> <message>Title must be less than 10 characters long.</message> </validator>
CDATA: <![CDATA[title.length < 10]]>
is using the expression validation not possible when validating string length?
