Description Andrew CLA 2011-07-13 11:46:12 EDT 
JSP validator do not understand "expr ? value1 : value2" EL operator. This fragment generates false error message:

<c:set var="customer" 
    value="${(empty PurchaserName) ? tx : fn:substring(PurchaserName, 0, 100) }"/>

The function tx:fn is undefined	sale.jsp

Lowering severity as this doesn't meet the criteria for a "blocker."

patch

The parser was turning the conditional expression and turning the two identifiers into a method invocation. Updated the el specification to look far enough ahead to make sure something is a method invocation.
