I don't. They are violating the JSP Specification if they support this.
In the JSP 1.3 Specification, Section 4.1 (page 68), you will find the
following statement:
"Duplicate ids found in the same translation unit
shall result in a fatal translation error."
The fact that you are doing this inside scriptlet conditionals does not
change the fact that you are using two <jsp:useBean> elements with the
same "id" attribute in the same page.
