> JSP EL that worked on JBoss AS 4.0.5.GA does not work on EAP. For example, the following does not work:
> <c:set var="truevalue" value="true" />
> <c:set var="falsevalue" value="false"/>
> <c:out value="${not empty param.yes?truevalue:falsevalue}"/>
> It throws this error:
> 2009-06-11 10:40:57,487 ERROR [org.apache.catalina.core.ContainerBase] Servlet.service() for servlet jsp threw exception
> org.apache.jasper.JasperException: /jsp/case305721.jsp(27,3) "${not empty param.yes?truevalue:falsevalue}" contains invalid expression(s): javax.el.ELException: Error Parsing: ${not empty param.yes?truevalue:falsevalue}
>        at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40)
> But this works with a space added before the colon:
> <c:out value="${not empty param.yes?truevalue :falsevalue}"/>
> This is a bug[1] that was originally fixed in Tomcat 6.0.18[2], but was subsequently found to cause a regression[3], so was re-implemented in 6.0.19.
