[Resin-interest] tag cast issues???
ARghh. If it's not one thing, it's another. I'm finally 99% in place with
resin-4.0.4, and suddenly I notice this stack trace, for a JSP tag defines like
this:
%...@tag body-content=empty
%%...@attribute name=value required=true rtexprvalue=true
type=java.lang.Long description=Duration value in seconds
%%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core;
%%@ taglib prefix=fmt uri=http://java.sun.com/jsp/jstl/fmt;
%%
long interval = (Long) pageContext.getAttribute(value);
boolean neg = interval 0;
interval = Math.abs(interval);
long hours = interval / 3600;
interval -= hours * 3600;
long minutes = interval / 60;
interval -= minutes * 60;
long seconds = interval;
hours = Math.abs(hours);
minutes = Math.abs(minutes);
seconds = Math.abs(seconds);
pageContext.setAttribute(neg, neg);
pageContext.setAttribute(hours, hours);
pageContext.setAttribute(minutes, minutes);
pageContext.setAttribute(seconds, seconds);

Re: [Resin-interest] tag cast issues???
I'm pretty sure resin is borking the Java file generation of my tag. I've
written a bug with all my notes about how the cast can't work as is:
