[json-lib-user] JSONObject.toBean() problem

[<ki...@ro...>]

Hi all.

I've run the code in the 'Getting Started' document.

------------------------------------------------------------
public static class MyBean{
private List data;

public List getData() {
return data;
}

public void setData(List data) {
this.data = data;
}
}

public static class Person{
private String name;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}
}

public static void testTest() throws Exception
{
String json = "{'data':[{'name':'Wallace'},{'name':'Grommit'}]}";
JSONObject obj = new JSONObject(json);
MyBean bean = (MyBean)JSONObject.toBean( obj, MyBean.class );
}
------------------------------------------------------------

And following exception occured.

------------------------------------------------------------
Exception in thread "main" net.sf.json.JSONException:

I think that at the 376 line in the JSONObject.java, invoking
JSONArray.toList(...) method,
the second parameter, 'beanClass' should not be passed.
Instead, null should be passed, I think.
The intended class of list item is 'Person', but 'beanClass' is 'MyBean',
so PropertyUtils cannot find 'name' property from 'beanClass'.

Doesn't anyone have this problem?

Sorry for poor english. :(
