I think I am bitten by the same bug here.
This piece of code of my Generator:
sw.print("public final void " + service.getName() + "(");
for (int i = 0; i < params.length; i++) {
if (i > 0) {
sw.print(", ");
}
sw.print("final " + genUtils.getClassName(params[i].getType()) + " "
+ params[i].getName());
}
sw.println(") {");
creates a method declaration like:
public final void serviceName(final int a, final String b) {
since about the same time yesterday my generator outputs this declaration:
public final void serviceName(final int arg0, final String arg1) {
and dropped the original name (a, b), which are used in annotations, so they
*must* be the same. It seems JParameter.getName() fails to return the 'real'
name of the parameter!
Test to reproduce:
1) Check out this SVN repo:
http://gwt-mobile-webkit.googlecode.com/svn/trunk/gwt-mobile-webkit/database/
2) hit 'ant' on the cmdline
3) watch the compiler errors. Look at source
[database]/build/out/samples/HelloDatabase/.gwt-gen/com/google/code/gwt/database/sample/hellodatabase/client/ClickCountDataService_SqlProxy.java
which is generated with
http://gwt-mobile-webkit.googlecode.com/svn/trunk/gwt-mobile-webkit/database/samples/hellodatabase/src/com/google/code/gwt/database/sample/hellodatabase/client/ClickCountDataService.java
as source.
