+ *
+ * Beware that the {@link onServerValidate onServerValidate} may be
+ * raised when the control to validate on the client side
+ * changes value, that is, the server validation may be called many times.
+ *
+ * After the callback or postback, the {@link onServerValidate onServerValidate}
+ * is raised once more. The {@link getIsCallback IsCallback} property
+ * will be true when validation is made during a callback request.
