Introspection regression from 1.5 to 1.6.2
------------------------------------------
Key: VELOCITY-736
URL: https://issues.apache.org/jira/browse/VELOCITY-736
Project: Velocity
Issue Type: Bug
Components: Engine
Affects Versions: 1.6.2
Environment: Sun JDK 1.6.0_16
Reporter: David Esposito
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());
}
}
