> I want to convert a bean class to a map (key=3Dthe name of the member,val=
ue=3Dthe value of the member).
> I'm using the method BeanUtils.describe(beanClass);
> (I'm using commons-beanutils 1.8.3, jdk 1.6.0_20, on commons-beanutils 1.=
5 it works)
> The problem is that the return value is incorrect, (the map contain only =
the first item from the array),
> the code:
> public class Demo {=20
>         private ArrayList<String> myList =3D new ArrayList<String>();=20
>         public Demo() {=20
>             myList.add("first_value");=20

>                     System.out.println(String.format("key=3D%s,value=3D%s=

>             }=20
>         }=20
>     }=20
>  =E2=80=A2The expected output:
> =20
> key=3DmyList,value=3D[first_value,second_value]
> key=3Dclass,value=3Dclass $Demo
>  =E2=80=A2But the real output is:
> =20
> key=3DmyList,value=3D[first_value]
> key=3Dclass,value=3Dclass $Demo
> As you can see the array contains two values but the output(and the map) =
contains only one,why??
