el expression as parameter in el function

Hello.

I have a tag file defined like this:

localeString is an el function defined in the tld like this:

when it tries to compile the tag file, the container ( glassfish 2.1) complains line this:

Can anyone help me by telling me exactly what am i doing wrong ? is it illegal to use an el expression as a string parameter of an el function ?

Thanks

figured it out: it should be
${mytags:localeString(language, "navbar.menubutton.label.users", "")}

not

${mytags:localeString(${language}, "navbar.menubutton.label.users", "")}

This is a mistake a lot of people make -- thinking that ${} is some sort of operator. It's not. It encloses the entire EL expression and should never be nested within one.

Thanks Bear !
