Description

I'm experiencing problems porting an existing struts 1.1 application on JDK 1.4.
Debugging the code, i have seen that the problem occur in getIndexedProperty,
because on jdk 1.3.1_02 return an instance of IndexedPropertyDescriptor while
in jdk 1.4.1_02 not!
To use indexed property on struts, whe declare 2 methods on the ActionForm: one
that return the entire list and one that return an indexed element

A simple class that reproduce the problem is:

public class FooForm extends ValidatorForm

{ protected List childs = new ArrayList(0); ... }

public List getChilds()

{ return childs; }

public ChildsBean getChilds(int index) {
if (index + 1 > childs.size()) {
for (int i = childs.size(); i < index + 1; i++)

{ childs.add(new ChildsBean()); }

}
return (ChildsBean) childs.get(index);
}

....
}

and the problem occur when i preload the forms values using a code like this

for (int j = 0; j < newChilds.size(); j++) {
BeanUtils.copyProperties(PropertyUtils.getIndexedProperty
(valBean,"childs",j), newChilds.get(j));
}
