Hello,
We're in the process of upgrading from Velocity 1.4 to 1.5 and we've noticed
that calling Java 5 enum objects that implement an abstract method fail to
render in 1.5 (they succeed in 1.4). Specifically, Velocity renders the
expression as writen (e.g. $myEnum.method() in a template gets output as
"$myEnum.method()).
I've written an example test case which demonstrates the issue:
public void parseAnEnumWithAnAbstractMethod() throws Exception {
runner.push("fancyEnum", FancyEnum.greeter);
// This works OK
assertEquals("greeter", runner.render("$fancyEnum.name()"));
// This fails and prints "$fancyEnum.messageFor(6)"
assertEquals("Hello there #6",
runner.render("$fancyEnum.messageFor(6)"));
}
Here's what the enum class looks like:
public enum FancyEnum {
greeter {
public String messageFor(int value) {
return "Hello there #" + value;
}};
public abstract String messageFor(int value);
}
And here's the the code I used to exercise Velocity:
public class VelocityRunner {
private VelocityContext context;
public VelocityRunner() throws Exception {
Velocity.init();
context = new VelocityContext();
}
public void push(String name, Object object) {
context.put(name, object);
}
public String render(String inputString) throws Exception {
StringWriter w = new StringWriter();
Velocity.evaluate(context, w, "velocityRunner", inputString );
return w.toString();
}
}
Am I missing something?
Thanks for your advice.
Cheers,
Dan
