Re: Working polymer example?
I've left this alone in the hopes that it would mature with the 2.8 release, but I still cannot get a sample to run using the tutorial on the gwtproject site. I have followed the instructions neurotically a couple of times, but the only improvement from when I tried it in January is that now a element appears in the host page, but it has no styling and does nothing. the webcomponents.js does load into the page but it throws these errors into the browser console: <https://lh3.googleusercontent.com/-GvRoEovj5z8/V9IWcNFlHxI/AAo/dwOq0OErfhgJ-H6sSwiliFUrp-hvnH5sACLcB/s1600/clip.tiff> I am using maven 3.3.3 with GWT 2.8.0-rc2, polymer with vaadin-gwt-polymer-elements 1.2.3.0. It seems clear that many people are working with it, but I cannot find the proper incantation to get the sample project off the ground. I noticed that the gwt 2.8 webappcreator generates a pom using a different GWT plugin than it used to. Could that be a factor? Any other ideas?

GWT Designer + MGWT library = Runtime exception
I'm trying to use GWT Designer design mode with the mGWT mobile widget library. I can reference the library widgets in XML and compile/run just fine, but when I try to switch from XML Source mode to Design mode in GWT Designer I get a runtime exception: Internal Error encountered unexpected internal error. This could be caused by a bug or by a misconfiguration issue, conflict, partial update, etc. java.lang.RuntimeException: Deferred binding failed for 'com.google.gwt.user.client.impl.DOMImpl' (did you forget to inherit a required module?) The mgwt library is in the build path, and I can freely use its classes in UIBinder XML files, but it always barfs up when I try to enter design mode. Since mGWT defines a larger number of target platforms than vanilla GWT, is it possible that GWT Designer is asking the mGWT library to instantiate an implementation of DOMImpl for a platform that base GWT doesn't have - causing the above exception? Since most of the mobile platforms share the same or similar DOM implementation (a la webkit) is there some way for the mGWT library to tell GWT Designer to use a safari implementation of DOMImpl as the default?

Re: Can AutoBeanFactory encode ListBeanObject ???
Thanks Colin,
That explains everything - my mistake was that I thought the
framework would automagically use the MyFactory interface to figure
out how to encode Lists of MyFactory objects. I still feel that it
should be able to do that, but clearly it doesn't. For anyone else who
gets confused by this - here is the working version of the test case:
public void testThing () {
Thing t1 = new Thing() { public String getName()
{ return
one; } };
Thing t2 = new Thing () { public String getName ()
{ return
two; } };
MyFactory fact = GWT.create(MyFactory.class);
AutoBeanThing t1Bean = fact.create (Thing.class,
t1);
AutoBeanThing t2Bean = fact.create (Thing.class,
t2);
String json =
AutoBeanCodex.encode(t1Bean).getPayload();
System.out.println (payload: + json);
final Thing [] pair = { t1Bean.as(), t2Bean.as() }; //
putting bean-wrapped objects in the list works.
Bunch b = new Bunch() { public ListThing getThings()
{ return
Arrays.asList(pair); } };
AutoBeanBunch bunchBean = fact.create (Bunch.class,
b);
// The following throws NullPointerException :(
json = AutoBeanCodex.encode(bunchBean).getPayload();
System.out.println (payload: + json);
}
On Jan 28, 3:30 pm, Colin Alworth niloc...@gmail.com wrote:
You are on the right track for this, but you need to wrap each model with
an autobean: encodeBean.as() is not the same instance as t1, even though it
is obtained from the autobean that wraps t1. You need to wrap each
instance, and include the wrapped instance in the eventual tree to be
encoded.
The list may also have trouble, it has been a while since I tried to build
something like this out. The approach I've taken, rather than manually wrap
the whole tree, was to wrap the root object, and use an autobean visitor to
walk the rest of the properties, wrapping and continuing further down the
tree. I found the code in
com.google.web.bindery.requestfactory.shared.impl.AbstractRequestContext.cl
oneBeanAndCollections(AutoBeanT)
to be helpful as a guide when copying autobeans, along with other aspects
of the internals of RequestFactory, which is based on Autobeans for
transport.

Can AutoBeanFactory encode ListBeanObject ???
I can't seem to figure out how to tell AutoBeanFactory to encode/
decode lists of objects. I have a simple bean object with string-
valued properties, and another bean object which has a list of the
first object. When I try to encode, I get a NullPointerException from
the AutoBeanCodex implementation. From the documentation in the wiki
(http://code.google.com/p/google-web-toolkit/wiki/AutoBean) it appears
that this is supposed to work, but what am I doing wrong?

public class BeanTest extends GWTTestCase {
interface MyFactory extends AutoBeanFactory {
AutoBeanThing thing ();
AutoBeanBunch bunch ();
}
interface Thing { // simple bean with one string-valued property
String getName ();
}
interface Bunch { // Simple bean with one ListThing valued property
ListThing getThings ();
}

Thing t1 = new Thing() { public String getName() { return
one; } };
Thing t2 = new Thing () { public String getName () { return
two; } };

AutoBeanThing encodeBean = fact.create (Thing.class, t1);
String json = AutoBeanCodex.encode(encodeBean).getPayload();
System.out.println (payload: + json);
final Thing [] pair = { t1, t2 };

Deferred locale selection/re-selection?
Hi, I need to write a multi-locale app that allows the user to change their locale at runtime. I would like to design the app so that I get the maximum benefits of GWT's deferred binding functionality with respect to locale. I must allow the user to log in to the app in one locale (say de-DE), and then later allow them to switch their locale setting to something else (say es-ES) without logging out. Ideally I would initially only load code and localization resources for the de-DE locale, and for most users that would be sufficient. Other users may wish to spontaneously change their locale, and at that point I would like to only load the code and localization resources for the new locale (es- ES or whatever). My problem is that the nocache.js script does its locale-specific code- swapping magic at boot time, and I would like to put that off until a bit later in the app. Can anyone recommend a strategy for achieving this design?

No UIBinder Event Handers in GWT 2.0?
The GWT 2.0 announcement got me all excited about the UIBinder, but I
can't seem to make the demo event handlers function. Is there some
module XML magic required to enable this? I created a new eclipse GWT
project, and added demo code from the source release, and although the
demo widgets are created and added to the page properly, none of the
event handlers function.
I tried manually adding ClickHandlers to the bound widgets, and that
didn't work either. Clearly I'm missing something. I also noticed that
the event handler code generated by the Eclipse Plugin's UIBinder
generator for a widget-based UI failed to work either.
Any insight or pointers are greatly appreciated.
My demo project was created by:
1) Creating new GWT project in eclipse for GWT2.0 no AppEngine
2) Replacing all generated code with a demo EntryPoint (see below).
3) Adding the GWT HandlerDemo.java and HandlerDemo.ui.xml
4) Setting the HandlerDemo package name to the project package
No joy :(

Re: what module contains com.google.gwt.core.ext.typeinfo.* ??
Ok, so I figured it out - it's not supposed to be inherited as a module. Because the Generator stuff is all at compile time you can't have your Generator classes in packages under the client source tree (unless you specifically exclude them in a source tag). So to anyone who is starting to work with the compile-time code generation facilities, be sure to keep your compile-time code out of your client package tree, or you will get the dreaded 'No source code is available for type' errors. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

with the id page.

Re: Page navigation in GWT
On Nov 21, 1:02 pm, jonbutler88 [EMAIL PROTECTED] wrote: Hi all I am new to GWT, though I have dabbled in C#/Java before so the language itself doesn't boggle me that much, but it seems some of the simpler concepts aren't sticking. Im pretty sure the answer to my question is so obvious, as I have not seen it answered in any of the tutorials on GWT on the web. What I wanted to know is, how do you do page navigation in GWT? For example I have my new class, with its onModuleLoad function, which is fine, but say I want to click a link and load a new page with a different onModuleLoad function? As others have pointed out, the Right(TM) way to do this is using the History mechanism. There are many strategies for working this into your application's internal syntax and structure. However, there are a few other basic concepts I think you might want some clarification on. First, you should think of your GWT app as a single HTML page, in which user and application events cause PORTIONS of the page (ie DOM elements) to change, be replaced, or loaded with content from the server or internal application logic. In general you will not be sending the user/browser to another real URL. Your initial HTML page is basically a canvas on which your GWT application spews up content in response to user or server events (the typical AJAX model). In the example of your login function, when your app has successfully received authentication credentials from the user, its next job will be to kick the login widgets off the page, and replace them with whatever is next. Second, you will probably find that the majority (if not all) of your user navigation paths are not coded in raw HTML. The GWT ui classes provide all the event handling and navigational connectivity that you would find in a typical desktop application. Although it is possible use raw HTML links to navigate your application, the GWT widgets are much easier to work with, test, and maintain than raw HTML files. So instead of following an a href=blah blahblah/a and going somewhere else, you will create event listeners that respond to mouse or key clicks which cause your app to change what is already there. Finally, you typically will only have one EntryPoint implementation with an onModuleLoad method in your application. That class will be responsible for initializing your application - probably by creating classes for the UI, classes for handling UI events, and classes for managing your applications internal state. In a lot of the samples, the class which implements EntryPoint also implements all of the UI, the event handlers, and the application logic, but that's only to reduce the amount of code you have to read. In any serious application you will want to factor those things out into different classes (as in MVC). It might be helpful to think of your EntryPoint.onModuleLoad() as if it were simply the main() method of a more traditional application.
