> Affects Versions: 1.0b3
> Environment: Operating System: Linux
> Platform: PC
> Reporter: Nick Bauman
> Assigned To: Velocity-Dev List
>
> Using this code:
> ---8<---
> import java.io.*;
> import java.util.*;
> import org.apache.velocity.VelocityContext;
> import org.apache.velocity.Template;
> import org.apache.velocity.exception.*;
> import org.apache.velocity.app.Velocity;
> public class VelTest {

> Template template = null;
> try {
> Properties props = new Properties();
> props.setProperty("file.resource.loader.path", args[0]);
> Velocity.init(props);
> VelocityContext context = new VelocityContext();
> HashMap map = new HashMap();
> map.put("wonka", "werfl");
> map.put("wertheimer", "wiffen");
> map.put("wicken", "witch");
> map.put("wooble", new Integer(3767));
> map.put("wablle", new Long(System.currentTimeMillis()));
> context.put("name", map);
> context.put("nameKeys", map.keySet());
> template = Velocity.getTemplate(args[1]);
> StringWriter sw = new StringWriter();
> template.merge(context, sw);
> System.out.println("template output: "+sw);

> } catch(Exception e) {
> System.out.println("Something bad happened: "+e);
> }
> }
> }
> ---8<---
> And using this template:
> ---8<---
> <HTML>
> <BODY>
> Hello. This is about the object \$name whose value is $name
> \$name is actually a $name.getClass().getName()
> Name is $name.size() in size
> <ul>
> #foreach ($element in $nameKeys)
> <li>key=$element value=$name.get($element)</li>
> #if ($name.get($element).getClass().getName().equals("java.lang.String"))
> The value is a String type
> #else if
> ($name.get($element).getClass().getName().equals("java.lang.Integer"))
> The value is an Integer type
> #end
> #end
> </ul>
> </BODY>
> </HTML>
> ---8<---
> I get this output:
> ---8<---
> <HTML>
> <BODY>
> Hello. This is about the object $name whose value is {wicken=witch,
> wonka=werfl, wooble=3767, wablle=990844112188, wertheimer=wiffen}
> $name is actually a java.util.HashMap
> Name is 5 in size
> <ul>
> <li>key=wicken value=witch</li>
> The value is a String type
> <li>key=wonka value=werfl</li>
> The value is a String type
> <li>key=wooble value=3767</li>
> if (true)
> The value is an Integer type
> <li>key=wablle value=990844112188</li>
> if (false)
> The value is an Integer type
> <li>key=wertheimer value=wiffen</li>
> The value is a String type
> </ul>
> </BODY>
> </HTML>
> ---8<---
> Notice the weird "if(false)" diddly-doos in there.
