JAVACODE TIP & TRICKS (DRAFT)
------------------------------------------------------------------------------

 1. Tag references When you enter a [tag] name in a
[JavaCode] body, unless you are using it as the
target of an assignment or accessing a method (by
following the tag name with a dot '.'), is will be
replaced by the tag value. If you want to pass a
reference to the tag to a function/method or to a
[TagRef] object, you can use the tag.ref() method,
which return a [TagRef] object.
