java.lang.Object
org.apache.tapestry5.corelib.internal.HiddenFieldPositioner
Used to position a hidden field (as part of a form-related component). Hidden fields are not allowed to go just
anywhere, there are rules, dictated by the (X)HTML schema, about where they are allowed. We use the
MarkupWriterListener

a
place to put content.-
