[opencms-dev] x:out and XPath

[Dwayne Kristjanson]

>From what I've read so far, no. The select uses Xpath variables, not JSP expressions. $dom is the value returned by pageContext.findAttribute("dom"). If I use ${dom} it will dump the DOM object into the string. My error might be in the Xpath expression itself, but I doubt it. I get the same kind of errors with the JSTL examples in /sites/default/alkacon-documentation/examples_jstl/xml/ as I do with my own code. So I must be missing something from my Tomcat install, but I don't know what. All I can say for sure is that I get a NullPointerException whenever I call code that uses the XPath features of the JSTL XML taglib.

Shouldn´t it read ${dom} ?
