question on EL Lambda expression in a JSP on Tomcat 8_0_15

[Anup Aggarwal]

Hi,

I am trying to run this EL Lambda expression in a JSP on Tomcat 8_0_15

${(incr = x->x+1; incr(10)}

But I get this exception

org.apache.jasper.JasperException: /TestLambda.jsp (line: 44, column: 42)
The function incr must be used with a prefix when a default namespace is
not specified

org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:42)



Thanks and help will be appreciated to resolve this.
