Subject [jira] [Created] (JEXL-129) Inner type attributes cannot be resolved in expressions
Date Wed, 08 Feb 2012 14:31:59 GMT
Inner type attributes cannot be resolved in expressions

                 Key: JEXL-129
             Project: Commons JEXL
          Issue Type: Bug
    Affects Versions: 2.1.1
         Environment: JDK 6
            Reporter: Antonio Agudo

When using inner types e.g. for unit tests, it is impossible to resolve bean attributes from
beans that are otherwise available in the JexlContext. I don't know about the implications
for real world systems, but in testing this can be a pain.

Junit Example: 

package test;

import org.apache.commons.jexl2.Expression;
import org.apache.commons.jexl2.JexlContext;
import org.apache.commons.jexl2.JexlEngine;
import org.apache.commons.jexl2.MapContext;
import org.junit.Test;

import static junit.framework.Assert.assertEquals;

public class TestJEXL {
    public void test() {
        JexlEngine jexl = new JexlEngine();
        Expression exp = jexl.createExpression("b.i + b.i");

        FakeBean b = new FakeBean();
        JexlContext jc = new MapContext();
        jc.set("b", b);

        Object results = exp.evaluate(jc);


    private static class FakeBean {
        private int i = 10;
        private String key = "myval";

        public int getI() {
            return i;

        public void setI(int i) {
            this.i = i;

        public String getKey() {
            return key;

        public void setKey(String key) {
            this.key = key;
