I am having the same problem. Until a fix is found you can hack the
hosted.html that gets injected in to your module's output directory.
var moduleFuncName = window.location.search.substring(1);
if (!moduleFuncName || !$wnd[moduleFuncName]) {
moduleFuncName = window.name;
}
moduleFuncName=your_module; // insert; around line 16;

[gwt-contrib] Comment on EnumOptimizations in google-web-toolkit
Comment by cromwellian:
Joel,
wouldn't this transformation work?
{{{
foo_Names = [FOO_0, FOO_1, FOO_2];
fooFuncs = { getMessage: [getMessage1, getMessage1, getMessage2] };
}}}
Enum's then become integer ordinals. `FooEnumType.name()` would return
`foo_Names[ordinal()]`
`FooEnumType.func()` would invoke
`fooFuncs[obfuscatedFuncName][ordinal](args)`.
The problem is, by the time you reach the JS AST, you've lost any idea that
these are enums. So it would have to be done at the JDT-Java AST stage I
think.
This is a special case of object inlining where you know that a given type
can only be instantiated with N different permutations, all field values
statically known at compile time. In which case, you can rip all of the
object's fields out to global singleton and replace them with a pointer
(integer or other reference)

The key point is that the usage of a type in one context would not affect
how the type itself could be optimized in other contexts. As it stands
today, we can't do the above optimization if anywhere in the program
someone calls `BasicList#add()`. A great practical example is Widgets
firing events. You want widgets to be *able* to fire events *if* someone
actually wants to listen to them. In the cases where you can see that there
are no listeners to a widget, you'd really like the entirely of the
even-firing infrastructur to completely disappear.
+=== Global Object Interning/Hoisted Inlining ===
+
+Inspired by Joel's attempts to optimize Java Enums, consider that we have
a class `Foo`
+
+{{{
+public class Foo {
+ final int field1;
+ final String field2;
+
+ public Foo(int x, String y) { this.field1=x; this.field2=y; }
+ public int getField1() { return field1; }
+ public String getField2() { return field2; }
+}
+}}}
+
+and this class is provably only ever instantiated with compile time
literal constants and contains no ability to mutate these fields.
+
+{{{
+new Foo(42, Adams);
+new Foo(99, Agent);
+new Foo(5, Johnny);
+new Foo(10100, Google);
+}}}
+
+Then the compiler may globally intern/hoist these field constants:
+{{{
+public class FooHoist {
+ public static int[] field1= {42, 99, 5, 10100};
+ public static String[] field2 = {Adams, Agent, Johnny, Google};
+}
+}}}
+
+And any reference to `Foo` may now be replaced with an ordinal index into
`FooHoist`. e.g. `new Foo(5, Johnny);` becomes `2`.
+
+This would allow the entire classtype for `Foo` to be pruned in many
circumstances, the chief example being Enum classes. In the case where
`Foo` is polymorphic, you need a separate dispatch table, but you can still
eliminate the type and it's subtypes.
+
+This optimization is mostly useful for Enums and Type-Safe enums.
+
== Semantic Techniques ==
Let us call a method semantic, if it is recognized by the compiler by
name, and the compiler has a heuristic for evaluating the same function,
discarding the original implementation. Semantic techniques are used by a
number of compilers to replace operations with intrinsically faster ones.
Consider the Java library function `Math.sin()`. While the library could
theoretically have an implementation of sin() using table lookup or power
series expansion, in some architectures, there is a native CPU instruction
for computing `sin`, and therefore, the JIT compiler can in many cases,
detect the call to Math.sin(), and replace it with an inlined instruction.
Let us call this technique _semantic inlining_.

[gwt-contrib] Comment on LightweightCollections in google-web-toolkit
Comment by tamplinjohn: For `MutableArray.freeze`, essentially changing a `MutableArray` to an `ImmutableArray` (even for existing references to the `MutableArray`) seems awkward, and will promote manual copies. I think the builder pattern is probably better here, since it is explicit that it exists to create an `ImmutableArray` rather than also being useful as a `MutableArray` later. If `MutableArray` extended `ImmutableArrayBuilder`, then you could not pass a `ImmutableArrayBuilder` to code that expected a `MutableArray` (without an explicit cast), and therefore the latter could depend on being able to mutate it later. Otherwise it seems that any callees who want to mutate the array must still make defensive copies lest someone else freeze that same instance. Maybe it is better to not have them related by inheritance but put all the methods as static in a shared utility class. It seems like separate annotations for complexity measures are tricky beyond the obvious ones -- would it be better to have `...@complexity(n^1/3)` so there is a single way to specify them, especially in the case of `O(n*m)` etc?

[gwt-contrib] Comment on UsingOOPHM in google-web-toolkit
Comment by dan.kozlowski:
I have successfully got the GWT and OOPHM working on Fedora 11 x86_64. here
is what i did.
Downloaded the latest GWT form subversion ( r5632 ) and built it according
to the directions linked above. then i had to extract the created SDK (
build/dist/gwt-linux-0.0.0.tar.bz2 ) to some place in my home folder
Downloaded the oophm svn branch
{{{
svn checkout http://google-web-toolkit.googlecode.com/svn/branches/oophm
oophm
}}}
Inside that project I had to make a few changes
{{{

Then i entered the firefox folder and ran make

then install the build .xpi file with firefox
finally I downloaded the Google Plugin and created a default Web
Application Project. For the GWT SDK i pointed it to the custom build one
that i made earler ( it comes up as gwt-linux-0.0.0.0 )
After that I just put in the default app and let it fly, no problems so far
