I've found an interesting error in GWT 1.5.3:
[ERROR] Line 14: Type mismatch: cannot convert from Test.Parametric.Number
s to Test.Parametric<T>.Numbers
[ERROR] Line 17: Type mismatch: cannot convert from Test.Parametric.Number
s to Test.Parametric<T>.Numbers
Compiling module test.Test

Rebinding test.client.Test
Checking rule <generate-with class='com.google.gwt.user.rebind.ui.ImageBun
dleGenerator'/>
[ERROR] Unable to find type 'test.client.Test'
[ERROR] Hint: Previous compiler errors may have made this type unava
ilable
[ERROR] Hint: Check the inheritance chain from your module; it may n
ot be inheriting a required module or a module may not be adding its source path
entries properly
To reproduce:
public class Test implements EntryPoint {
static class Parametric<T> {
enum Numbers {
ONE, TWO;
}
}
public void onModuleLoad() {
switch (Parametric.Numbers.valueOf("ONE")) {
case ONE: // Line 14
System.out.println("ONE");
break;
case TWO: // Line 17
System.out.println("ONE");
break;
}
}
}
Removing the parameter from the type enclosing the enum fixes the problem.
The above *works* in trunk and 1.6, but I searched a little bit and I
couldn't find anything in the issue tracker that appeared related.
Upgrading to 1.6/trunk isn't a good option for me at the moment, so
I'm hoping that someone has seen this before and could help me find
the change that fixed it. If it's a simple patch, I can apply it to
1.5.3 until such time as an upgrade is possible. Moving the enum to a
non-parameterized type would probably work as well, but I'm loathe to
do too much redesign on account of a compiler bug that appears to
already have been fixed.
