Description

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; }

}
