Re: TreeViewModel and AsyncDataProvider
I use a custom TreeViewModel instead of handling selection events.
When a user clicks on a level 1 node, TreeViewModel.getNodeInfo(...)
method is called
The method creates a data provider that corresponds to the type of
value parameter.
The data provider initiates an RPC call in its constructor.
When the data provider receives results back from the server it
populates itself with the data received by calling updateRowCount()
and updateRowData()
This works well when the number of children under parent node is
small. If it is large AbstractDataProviderT.onRangeChanged() can be
used to query only currently visible children.
Is this something you are looking for?

I have a 3 level CellBrowser. Everything is working fine using a
ListDataProvider except that it's too long to grab the data from the server.
So I want to use the AsyncDataProvider to fetch only the data that the user
actually needs. Basically what I want to do is when the user selects the
level1 value, the level2 provider executes a RPC call to get the level2 data
based on the selected level1 parent. The problem is that the onRangeChanged
method is called before the onSelectionChange, so when the RPC call is done
the level1 value is still null. What is the proper way to use
AsyncDataProvider to grab the level2 data depending on the level1 selected
value?
public class SportTreeModel implements TreeViewModel, Handler {
private AsyncDataProviderLevel1Node level1Provider;
private AsyncDataProviderLevel2Node level2Provider;
private final SingleSelectionModelLevel1Node level1SelectionModel;
// In the construtor I create these objets
// In getNodeInfo I link a cell with the data provider and the selection
model
@Override
public void onSelectionChange(SelectionChangeEvent event) {
Object src = event.getSource();
if (src == level1SelectionModel) {
Level1Node level1 = level1SelectionModel.getSelectedObject();
((MyAsyncLevel2Provider)
level2Provider).setLevel1(level1.getValue());
}
}
}
Thanks

Display an Image from JPA entity.
Hello.
I'm trying to figure out how to display Images using the
requestFactory.
I have an entity that represents an Image and I want to have a simple
list of all images.
I'm wondering what data type should I use for holding the image data.
The RequestFactory docs mention that primitives are not allowed
however
if I create an entity like this one:
@Entity
public class Picture {
...
@Lob
@Basic(fetch=javax.persistence.FetchType.LAZY)
private Byte[] data;
...
}
I'm getting runtime exception saying Byte is not a primitive type.
What would be the best way to put JPA entities. requestFactory and
UiBinder together?

writing chrome extensions with GWT- need documentation or simple example
The Chrome extensions site (http://code.google.com/chrome/extensions/ index.html) has some great documentation and examples of writing Chrome Extensions in Javascript, but surprisingly, there's not a hint as to how one might implement one using GWT. So I downloaded the source to SpeedTracer, and extracted the relevant pieces of code from com.google.chrome.crx.client. After lots of guesswork, I was able to get a linker configured that generated a manifest.json for me, and at least put an icon into the browser. But I can't seem to figure out how to actually access the UI from GWT- every time my Extension EntryPoint attempts to do anything useful I get \$wnd is undefined. Is there a Hello World level example project somewhere that shows how to correctly integrate GWT with the Chrome Extension wrapper found in SpeedTracer?

Re: Display an Image from JPA entity.
Hello, I think it would be easiest not to transfer the actual image data with RequestFactory. Just provide the Image-URI within the entities transferred by RequestFactory and have it point to a special servlet that serves the actual images. This way you can also use the AppEngine Bloblstore (if you're running on AppEngine). I'm not sure you can do anything useful with byte[] data on the client anyway, the only way to directly transmit the image using RequestFactory would imho be to convert it to a Base64 string (which you use as a CSS background-image to display it).

MenuBar-smartgwt

Re: RequestFactory don't play nice with guice?
Since GWT 2.1.1 is here: Another way of doing it would be to just use a normal ServletModule as per the Guice user guide: http://code.google.com/docreader/#p=google-guices=google-guicet=ServletModule Then bind the RequestFactoryServlet; bind(RequestFactoryServlet.class).in(Singleton.class); serve(/gwtRequest).with(RequestFactoryServlet.class); Otherwise following the RequestFactory documentation you can use: requestStaticInjection(MyDomainClass.class) in your module to inject the PersistenceManager (or EntityManager) statically. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: MenuBar-smartgwt
In GWT 2.1.1 MenuItem implements HasEnabled interface which helps
enabling/disabling menus dynamically:
public interface HasEnabled {
boolean isEnabled();
void setEnabled(boolean enabled);
}
But I'm not sure if SmartGWT is compatible with GWT 2.1.1

Re: GWT 2.1.1 RequestFactory Strange Exception
I cannot understand how I could persist a domain object, using the new service layer. Because when I call pm.makePersistent(arg); I need to have access to the instance of the domain object that is going to be stored. Before, I could just write pm.makePersistent(this); according to the example, referring to the domain object. But know, where I call the same method through a service, how can I have access to the domain object. Should I call Locator, and how exactly could I do that? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: gwt,maven,testing
HI! At GWT side you can access to client classes only. i.e. com.etmen.simplewebapp.SimpleSampleProject.server.app.PersistencyManager should be in client package if you want to use it in GWT side (even if you want to use it for testing).

Re: Exposing my GWT API via web/RESTful service - can it be done (easilyish)?
Thanks to all for the feedback - just wanted to share some reactions 1. I was surprised by the lack of responses re: restlets - that seemed to be a promising technology 2. Some of the suggestions/links seemed a little bit over my head - but that is probably just because my head is at a pretty low place :). But, pondering this a little more, I thought of a different approach that might make a lot more sense. The bottom line is that my application will need an API that can be called by many clients, including the GWT UI that we would like to build. I was thinking of trying to expose the Service API that is in the GWT application. But wouldn't another approach be to build a RESTful interface to my data as the API and then use that API from my GWT application (as there seem to be standard ways of accessing REST APIs from the GWT server side). Other apps could get to the REST API using whatever method they chose and I don't have to end up implementing the API twice. Thoughts and comments are definitely appreciated! Esp those using short words :).
