Combined property access ( b.mapped(bar/foo) ) throws excception

           Summary: Combined property access ( b.mapped(bar/foo) ) throws
                    excception
           Product: Commons
           Version: 1.4 Final
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: Bean Utilities

Combined property access ( b.mapped(bar/foo) ) in beanutils 1.4.1 
throws excception. It used to work in 1.3. I think changes related
to supporting '.' in keys for mapped access are cousing it.

There was 1 error:

Following are a two classes and JUnit test case:

package org.apache.commons.beanutils.test;

import junit.framework.TestCase;

import org.apache.commons.beanutils.PropertyUtils;

/**
 * Tests combined property access.
 * 
 * @author Vjekoslav Nesek
 */
public class CombinedPropertyAccessTest extends TestCase {

	/**
	 * Constructor for CombinedPropertyAccessTest.
	 * @param test
	 */
	public CombinedPropertyAccessTest(String test) {
		super(test);
	}
	
	public void testA_B_Mapped() throws Exception {
		A a = new A();
		B b = new B();
		a.setB(b);
		
		assertEquals(PropertyUtils.getProperty(a, "b.mapped
(bar/foo)"), "bar/foo");
	}

	public static void main(String[] args) {
		junit.textui.TestRunner.run(CombinedPropertyAccessTest.class);
	}
}


package org.apache.commons.beanutils.test;

public class A {

	private B b;

	/**
	 * Returns the b.
	 * @return B
	 */
	public B getB() {
		return b;
	}

	/**
	 * Sets the b.
	 * @param b The b to set
	 */
	public void setB(B b) {
		this.b = b;
	}

}

package org.apache.commons.beanutils.test;

public class B {

	public void setMapped(String key, Object value) {
	}
	
	public Object getMapped(String key) {
		return key;
	}

}
