How to change the panel in Activity.start()
I want to start one activity (my form) inside another (my app). I am trying to do that with the 2.1 MVP Framwork and would like to know... 1) Is it possible to configure the ActivityManager (or add place parameter) so that my FormActivity.start() receives a inner panel of my app instead of the outer one set by activityManager.setDisplay(appWidget) when the EntryPoint was loaded? 2) The documentation reads "your app could create a CompositePlace, CompositeActivity, and CompositePlace.Tokenizer classes that delegate to the constituent members". Have anyone implemented that? (and would be kind enough to share) 3) Is there another way or recommended practice?

GWT + Web SQL
Hello, I am building a GWT app that uses Web SQL Local Storage ( http://dev.w3.org/html5/webdatabase/ ). The problem is that the Web SQL API uses callback functions as arguments. Is it possible to pass "Java" callbacks to JSNI? Thanks, Julio -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: HTML5 Offline GWT APP
The filter didn't work for me, i don't know exactly why, i am guessing
that static files (such as gwt artifacts) under GAE dev have different
access...

Re: HTML5 Offline GWT APP
I am doing like the Google IO Linkers video:
@LinkerOrder(Order.POST)
public class OfflineLinker extends AbstractLinker {
@Override
public String getDescription() {
return "HTML 5 Offline Linker";
}
@Override
public ArtifactSet link(TreeLogger logger, LinkerContext context,
ArtifactSet artifacts) throws UnableToCompleteException
{
ArtifactSet artifactSet = new ArtifactSet(artifacts);
StringBuilder buf = new StringBuilder();
buf.append("CACHE MANIFEST\nindex.html\n");
buf.append("#").append(System.currentTimeMillis()).append("\n");
for(EmittedArtifact
artifact:artifacts.find(EmittedArtifact.class)){
if(!artifact.isPrivate()){
buf.append(artifact.getPartialPath()).append("\n");
}
}
EmittedArtifact artifact = emitString(logger, buf.toString(),
"gt.manifest"); //my manifest file name
artifactSet.add(artifact);
return artifactSet;
}
}
I also needed this servlet (mapped to /gt.manifest) :
public class ManifestServlet extends HttpServlet{
@Override
protected void service(HttpServletRequest req, HttpServletResponse
resp)
throws ServletException, IOException {
resp.setContentType("text/cache-manifest");
RequestDispatcher disp = req.getRequestDispatcher("/gt/
gt.manifest");
disp.forward(req, resp);
}
}
It seems to be working, but debugging is not easy.

Re: HTML5 Offline GWT APP
Thanks Arthur, the linker works perfectly. I also made a servlet to add the "text/cache-manifest" content type and redirect to the generated manifest file. But i still can't use my app ofline. Is there any browser capable of debugging HTML5 offline cache? Know i have a error event, discovered using this script: http://jonathanstark.com/blog/2009/09/27/debugging-html-5-offline-application-cache/ But the response is coming correctly, but i don't know what i am doing wrong.

Re: GWT.runAsync and Command Pattern
Would it be possible to wrap / unwrap the request, removing the
immediate inheritance or the compiler must generate the type
serializers eagerly for all types ever reachable?
Thanks for the advice on the interface, Frederico, i hope i can use
it. In my case, code splitting is more important than commands, i wish
they weren't mutually exclusive.

GWT.runAsync and Command Pattern
Hi,
I am trying to split a GWT app that uses the command (action) pattern.
The problem is that "GWT.create(ActionService.class)" causes every
subclass of the return and parameter types to be included in the
initial fragment.
For instance, my action interface is:
public interface ActionService extends RemoteService {
T execute(V req) throws
ActionFailedException;
}
the problem is that "module1.SomeRequest" and "module2.OtherRequest"
gets included in the initial fragment.
Do you see a way around this?
Thanks,
Julio Faerman

Re: How to build event hierarchy?
Thanks Jeff! I wonder if it would better to implement a HandlerManager that understands event type hierarchy or add a "type" parameter to the event and do the if/switch in the event handler.

How to build event hierarchy?
Hi, In my game UI i have several events, from generic to specific ( GameEvent > PlayerMessageEvent > PlayerVoteEvent ... ). Some widgets are interested in all events, logging all GameEvents for instance, and other are only interested specific events, showing all player votes for example. Given that event listeners must listen to a single GwtEvent.Type using the HandlerManager, what is the best way to implement such system? Should i add the same listener for all types or the HandlerEvent can handle inheritance?

bottom and the cell border.

public class MyApp implements EntryPoint {

Grid grid = new Grid(1,1);
Image image = new Image();
image.setUrl("http://shpyrko.files.wordpress.com/
2007/07/31persistenceofmemory.jpg");
grid.setWidget(0,0,image);
grid.setBorderWidth(1);
RootPanel.get().add(grid);
}
}

MVP + Places
Hi, I am trying to implement the "Places" abstraction over the history service in my GWT MVP app. I am finding it very hard to get it working with "hierarchical" places ( token=/order/123/item/1 ), because i would not like to redraw the entire screen ( container.clear() ) when the place is changed to somewhere near ( token=/order/123/item/2 ), unless that is required. In the attempt of discovering what to redraw, etc, i have produced a huge amount of spaghetti code. The best code on this i have found so far is http://www.amateurinmotion.com/articles/2010/02/01/gwt-history-management-with-places.html, but it is also unclear. If anyone have been through similar issues and could share some solutions, it would be of tremendous help. Or, if someone wants to build a "hierarchical mvp" places library, i would be glad to help the endeavour.
