Subject: RE: tiles breaks x:forEach
Well, I'm not sure this is helping you any, but I'm curious to see where it
leads ;-). I wish I knew a bit more about Tiles internals, I haven't really
used
it all that much. Anyway, the stack trace is still making me scratch my head
(order of execution):
JobSearch_jsp._jspx_meth_c_set_10(JobSearch_jsp.java:769)
JobSearch_jsp._jspx_meth_x_out_0(JobSearch_jsp.java:793)
...
XPathUtil$JstlVariableContext.getVariableValue
XPathUtil$JstlVariableContext.notNull
and the exception is thrown with message:
$prefix:javax.servlet.forward.request_uri
Which, AFAICT, means getVariableValue was trying to do something like:
return
notNull(pageContext.findAttribute("javax.servlet.forward.request_uri"),
null,
"javax.servlet.forward.request_uri");
Can you correlate lines 769 and 793 of the generated code with
JobSearch.jsp?
Huh, there seems to be a bug in the 1.1.0-B1 version of XPathUtil.
JstlVariableContext.notNull essentially looks like:
private Object notNull(Object o,
String prefix,
String localName) throws UnresolvableException {
if (o == null) {
throw new UnresolvableException("$" +
(prefix==null?"":"prefix"+":") +
localName);
}
return o;
}
Which means that instead of seeing the *value* of prefix in the exception
message (when it's non-null), you'll see the literal "prefix". So it should
probably be:
private Object notNull(Object o,
String prefix,
String localName) throws UnresolvableException {
if (o == null) {
throw new UnresolvableException("$" +
(prefix==null?"":prefix+":") +
localName);
}
return o;
}
Obviously, that shouldn't be impacting your app at all, but you never know
what
you'll find when you go rooting through code...
