OT: BeanUtils 1.7 and 1.8

[Giovanni Azua <gi...@imc.nl>]

hi,

Sorry for the of-topic but given that BeanUtils is heavily used in 
Struts, can anyone suggest why this test does not pass neither in 1.7 
nor 1.8? alternative way using BeanUtils? I had to end up implementing 
my own Reflection-based copyProperties ...

    
//------------------------------------------------------------------------
    public void
    testCopyProperties()
    throws Exception
    {
        class SomeBean
        {
            
//----------------------------------------------------------------
            public final double
            getPropertyA()
            {
                return thePropertyA;
            }

            
//----------------------------------------------------------------
            public final void
            setPropertyA(double aPropertyA)
            {
                thePropertyA = aPropertyA;
            }

            
//----------------------------------------------------------------
            public final double
            getPropertyB()
            {
                return thePropertyB;
            }

            
//----------------------------------------------------------------
            public final void
            setPropertyB(double aPropertyB)
            {
                thePropertyB = aPropertyB;
            }

            
//----------------------------------------------------------------
            /** (non-Javadoc)
             * @see java.lang.Object#toString()
             */
            @Override
            public String
            toString()
            {
                return "(" + getPropertyA() + ", " + getPropertyB() + ")";
            }           

            
//----------------------------------------------------------------
            // members
            
//----------------------------------------------------------------
            private double thePropertyA = 0;
            private double thePropertyB = 0;
        }
       
        Object myBean = new SomeBean();
         
        String myExpected = "(1.0, 1.0)";

        Map<String, Object> myMap = new HashMap<String, Object>();
        myMap.put("PropertyA", 1.0);
        myMap.put("PropertyB", 1.0);

        BeanUtilsBean.getInstance().copyProperties(myBean, myMap);
       
        assertEquals("BeanUtilsBean.copyProperties did not work as 
expected",
            myExpected, myBean.toString());       
    }   

TIA,
regards,
Giovanni

You should ask this on the commons user list:
  http://commons.apache.org/beanutils/mail-lists.html

...but the reason is because you have used the wrong names for keys in
your Map - the first character should be lower case (so "properyA" and
"propertyB") - this is the java beans spec

If you change the key names then it works.
