* The fact that you can use a value binding expression on nearly
every attribute makes using rt expressions redundant ... you can
do anything you need with a value binding anyway.
A very powerful feature in JSP 2.0 are "Custom Tags".
Having a bean Foo in your application with several instances.
Now you write some code to edit this bean. If you put this code
into a custom tag like
WEB-INF/tags/beans/foo.tag begin ------------------------------
<%@ attribute name="bean" %>
<h:outputLabel value="here comes my bean: " />
<h:inputText value="#{${bean}.firstName}" />
<h:inputText value="#{${bean}.secondName}" />
foo.tag end --------------------------------
you can use this snip many times on your jsp like
page.jsp begin ------------------------------
<%@ taglib tagdir="/WEB-INF/tags/beans" prefix="beans" %>
<beans:foo bean="foo1" />
<beans:foo bean="foo2" />
<beans:foo bean="foo3" />
page.jsp end --------------------------------
Unfortunately this does not work. Because of the rtexpression=false.
In tobago we decided to enable the feature, to make such things work.
Is there a way in JSF 1.2 / JSP 2.1 to make such sniplets run without
dublicating code?

In JSF 1.2 / JSP 2.1, the concepts are getting unified ... but in the
mean time (when the JSP container doesn't know what a value binding
expression is) this was the decision made at the JSF spec level.
