James Phillpotts commented on SLING-2455:
-----------------------------------------
This could be fixed by implementing an ELResolver that did something along the
lines of the following for getValue:
if (base instanceof Node) {
Node n = (Node)base;
if (n.hasProperty(property.toString())) {
context.setPropertyResolved(true);
return n.getProperty(property.toString());
}
return null;
You'd then need appropriate implementations for getType, setValue and
isReadOnly.

> Components: Scripting
> Environment: Mac OSX
> Reporter: Sandro Boehme
> Priority: Minor

> At the latest trunk (rev.1309704) a jstl expression within a <c:forEach> tag
> throws the jsp compile error
> "org.apache.sling.scripting.jsp.jasper.el.JspValueExpression cannot be
> resolved to a type"
> Example jsp:
> <%@ page session="false"%>
> <%@ page isELIgnored="false"%>
> <%@ page import="javax.jcr.*,org.apache.sling.api.resource.Resource"%>
> <%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c" %>

> I know you know how to do that but just to make it easier for you, here are

> curl -u admin:admin -F"sling:resourceType=el" -F"prop1=val1" -F"prop2=val2"
> http://localhost:8080/content/mynode
> curl -X MKCOL -u admin:admin http://localhost:8080/apps/el
> curl -u admin:admin -T el.jsp http://localhost:8080/apps/el/html.jsp
> URL to test: http://localhost:8080/content/mynode.html
