27  * This is the <code>BeanInfo</code> descriptor for the
28  * <code>org.apache.strutsel.taglib.html.ELResetTag</code> class. It is needed
29  * to override the default mapping of custom tag attribute names to class
30  * attribute names.
31  *<p>
32  * In particular, it provides for the mapping of the custom tag attribute
33  * <code>disabled</code> to the instance variable <code>disabledExpr</code>.
34  *<p>
35  * This is because the value of the unevaluated EL expression has to be kept
36  * separately from the evaluated value, which is stored in the base class. This
37  * is related to the fact that the JSP compiler can choose to reuse different
38  * tag instances if they received the same original attribute values, and the
39  * JSP compiler can choose to not re-call the setter methods, because it can
40  * assume the same values are already set.
