Description

When upgrading from Velcocity 1.5 to 1.6.2, the following snippet of code changed behavior.

In Velocity 1.5, the output was:

The file upload exceeded 100

In Velocity 1.6.2, the output is:

The file upload exceeded $ex.permittedSize

There is nothing in the velocity log file to help me identify why it's not resolving 'permittedSize' to the correct bean method.

Here is a test program to replicate the problem. The context variable in question is the Commons FileUpload exception class documented here:

http://commons.apache.org/fileupload/apidocs/org/apache/commons/fileupload/FileUploadBase.SizeLimitExceededException.html

I am using commons-fileupload-1.2.jar

import java.io.StringWriter;
import org.apache.commons.fileupload.FileUploadBase;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;
import org.apache.velocity.context.Context;

public class Main {
public static void main(String[] args) throws Exception

{ VelocityEngine e = new VelocityEngine(); String testTemplate = "The file upload exceeded $ex.permittedSize"; StringWriter out = new StringWriter(); Context ctx = new VelocityContext(); FileUploadBase.FileSizeLimitExceededException ex = new FileUploadBase.FileSizeLimitExceededException("too big!", 50, 100); ctx.put("ex",ex); e.evaluate(ctx, out, "Tester", testTemplate); System.out.println(out.toString()); }

}
