[2.0RC1] Incorrect casting for generic argument #43

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.  Have class such as:
public class Property<E> {
private E value;
public void setValue(E val) {
this.value = val;
}
}
2.  Try and compile.
3.  Get error 
[INFO]       [ERROR] Line 79:  E cannot be resolved
[INFO]       [ERROR] Line 79:  Syntax error on token "extends", . expected

What do you see instead?
    public void setFieldValue(Object instance, String fieldName, Object value) {
      com.xteconline.desktop.client.state.Property content = (com.xteconline.desktop.client.state.Property)instance;
      if (fieldName.equals("value")) {
        content.value=(E extends java.lang.Object)value;
      } else     super.setFieldValue(instance, fieldName, value);
    }

What version of the product are you using? On what operating system?
2.0RC1 on Linux.

Please provide any additional information below.

I'm also using the build attached to 
http://code.google.com/p/gwt-ent/issues/detail?id=40

It appears it should probably be using .getParameterizedQualifiedSourceName() 
instead of .getQualifiedSourceName() in ReflectionCreator.setFieldValue for the 
line:
String value = unboxWithoutConvert(jField.getType().getQualifiedSourceName(), 
"value");

I would try and build it against the source in svn, but I can't get that to 
compile.

Have u found any solution for this issue? I get the same.

Yeah, I got it to build.  I'm attaching it with the fix, which I believe was 
just doing what I said above (and also getting it to compile against GWT 2.2+). 
 Let me know if it works for you as I've also actually moved on from using 
gwt-ent since all I used it for was creating reflection information and created 
my own due to many bugs I've found with gwt-ent and it not being a very active 
project.

Somehow that's a null I never hit.  I've put a null-check for it.
