Cannot assign object [] of type class java.util.LinkedList to field public java.util.List

[kerbymart]

Given that we have

@RuntimeRetention
@ReflectionStrategy(keepEverything=true)
public class ParentBean {
    public List<ChildBean> children;
}

and

@RuntimeRetention
@ReflectionStrategy(keepEverything=true)
public class ChildBean {} 

Doing:

List<ChildBean> children = new LinkedList<ChildBean>();
ParentBean parent = new ParentBean();
GwtReflect.fieldSet(Parent.class, "children", parent, children);

Will result into this error:

[ERROR] Alert: Cannot assign object [] of type class java.util.LinkedList to field public java.util.List com.mycompany.ParentBean.children

[kerbymart]

A workaround to this bug is to use LinkedList as field type instead, like:

@RuntimeRetention
@ReflectionStrategy(keepEverything=true)
public class ParentBean {
    public LinkedList<ChildBean> children;
}

@kerbymart did you run GwtReflect.magicClass on ParentBean first?

[JamesXNelson]

I looked, and the fieldGet/fieldSet methods were not hooked up correctly for flyweight usage, so they currently still require calling magicClass to fill in runtime lookup maps.
