Re: when to use AsyncDataProvider instead of CellTable.setRowData ?
I think where we have a complex view which has a number of cell widgets displaying different representation of same data, or maybe related data, instead of using setRowData, setRowCount on each and every one of them, we can use one AsyncDataProvider to provide data for them. Yes. And a single data provider that provides data for multiple displays can optimize access to internal cache. If a display requests a range that has already been served to a different display, the data provider can simply return cached data instead of making request to a server. one question, do we need to write event handling code for notifying all the cellwidgets that have a common AsyncDataProvider ? or AsyncDataProvider will notify them ? Typically a user (through a pager or a scrollbar) would initiate onRangeChange() on the data provider, and the data provider would call the display back (setRowData/Count) right away (if the data is in the provider's cache) or from the remote server's callback (if it needs to request the data form the server). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: dilemma in identifying correct Activities, Presenters and Views in New Google Group-like app
IMO, it depends how connected and coupled you want your components. Having 3 display regions, you have very specialized and loosely coupled activities, and they have to communicate through events on the event bus. With a single display region, you have a more complex activity but its inner parts can call one another more directly. The fact that you don't always have the center-north and center-south regions is not really relevant here (well, if your activities start asynchronously, you might experience some flicker when switching between two places that both need the regions, but that's another issue – disclaimer: we've not yet (re)introduced such optional regions in our app, so I have no concrete experience with this) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Receiver.onViolation() is called several times
That's because when there's an error or violation, the RequestContext is un-frozen and made reusable, but (obviously) not cleared. Given that Request#fire(Receiver) is equivalent to Request#to(Receiver)+Request#fire() (where Request#fire() is equivalent to RequestContext#fire()), what you're doing here is equivalent to: First time: context.getItem(id).to(new Receiver()); context.fire(); Second time: context.getItem(id).to(new Receiver()); context.getItem(id).to(new Receiver()); context.fire(); Third time: context.getItem(id).to(new Receiver()); context.getItem(id).to(new Receiver()); context.getItem(id).to(new Receiver()); context.fire(); Each time, you enqueue a new *invocation* with its own new Receiver, and because validation is done between processing *operations* and *invocations*, the violations are reported to each and every Receiver on the client-side. If you put a break-point in your Receiver, you'll see that each onViolation call is made on a distinct Receiver instance. So, what should you do? Rule of thumb: if you somehow process violations, make sure you enqueue * invocations* once only and only re-fire(). In samples using RF with Editors for instance (DynaTableRf, Expenses), you'll see that the call to save()/persist() is *enqueued* very early (sometimes even before the RequestFactoryEditorDriver#edit() method is called) and when clicking the save button it only fire()s the RequestContext. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: when to use AsyncDataProvider instead of CellTable.setRowData ?
In general, use AsyncDataProvider/AbstractDataProvider/ListDataProvider when your data is dynamic or you support paging. The DataProviders handle RangeChangeEvents from CellTable and ensures that only the correct data is sent to the CellTable. Use CellTable#setRowData() when your data is static and you just want to display it on the page. You don't need a data provider if the data is not going to change while the app is running.

Re: GWT 2.1.1. + Deploy in Tomcat
can you plz specify what the problem is?

Sending request with proxy created from other request ?
Hi,
the situation is:
@Service(value = PersonManager.class, locator =
InjectingServiceLocator.class)
public interface PersonRequest extends RequestContext {
RequestVoid persist(PersonProxy personProxy);
}
PersonRequest firstRequest = requestfactory.getPersonRequest();
PersonRequest secondRequest = requestfactory.getPersonRequest();
.
PersonProxy personProxy = firstRequest.create(PersonProxy.class);
personProsy.setName(John);
..
secondRequest.persist(personProxy).fire();
.
As a result, all properties of the parameter person in the
personManager.persist(Person person) are null.
Why that happens?
Is there any solution?
Regards, Mihail Lesikov

Re: Sending request with proxy created from other request ?
And when I say I would have expected an exception, I really mean an IllegalArgumentException(Attempting to edit an EntityProxy previously edited by another RequestContext) (AbstractRequestContext#addInvocation calls retainArg, which calls edit() on the proxy — or maybe there's a bug in retainArg that it should check instanceof BaseProxy instead of EntityProxy, and your PersonProxy is a ValueProxy?) my PersonProxy is ValueProxy I forgot to say that I use gwt compiled with the latest changes directly form the trunk.

MultiSelectionModel with CellList
Hi,
I have created a celll that extends AbstractCell. I want to use it
with a CellList and a multiSelecitonModel. However, I cannot select
more than one item. Is it possible to select more than one item in a
CellList? With Ctrl + shift + click? I tried a lot of combinations...
I read a lot about there being issues with selection and cells. I
just updated to 2.1.1 and hoped it would work now.
I realized that the render signature was changed in 2.1.1. Do I have
to do anything with the Context?
This is how my Cell looks like:
static class SensorCell extends AbstractCellSensor {
private final String imageHtml;
public SensorCell(ImageResource image) {
this.imageHtml =
AbstractImagePrototype.create(image).getHTML();
}
@Override
public void render(Context context, Sensor
value,SafeHtmlBuilder sb)
{
if (value == null) {
return;
}
sb.appendHtmlConstant(table);
// Add the contact image.
sb.appendHtmlConstant(trtd rowspan='3');
sb.appendHtmlConstant(imageHtml);
sb.appendHtmlConstant(/td);
// Add the name and address.
sb.appendHtmlConstant(td style='font-size:95%;'ID:
);
sb.appendEscaped(value.name);
sb.appendHtmlConstant(/td/trtrtdStatus: );
sb.appendEscaped(String.valueOf(value.status));
sb.appendHtmlConstant(/td/trtrtdSubscribed: );
sb.appendEscaped(String.valueOf(value.subscribed));
// close the html
sb.appendHtmlConstant(/td/tr/table);
}
}
Here I add the selectionModel and set the selectionChangeHandler...
I really don't know what else to do.
cellList.setSelectionModel(multiSelectionModel);
// Add a new handler to register when the selection of
// functionalities has changed
multiSelectionModel.addSelectionChangeHandler(selectionChanged);
Thanks in advance,
Flo

Re: Sending request with proxy created from other request ?
I'll describe my problem better:
The main goal of my task is a workflow of a contract signing.
interface ContractProxy extends ValueProxy{
CustomerProxy getCutomer();
void setCustomer(CustomerProxy customer);
AddressProxy getAddress();
void setAddress(AddressProxy address);
ListItemProxy getItems();
void setItems(ListItemProxy items);
}
https://lh3.googleusercontent.com/_aoD2oLHFruo/TUE9VIJVPUI/AbA/E-WaHiebbq0/2011-01-27%2009.38.23.jpg
1. Loading empty contractProxy
- creating contractRequest
- editing the proxy in ContractEditor (Zone 4) (editor.edit(contracProxy
,contractRequest))
2. Zone 1 (Customer Editor) :
- set customer data
- persist the customer by customerRequest
3. Zone 2 (AddressEditor)
- set address data
- persist the street from the address by addressRequest
4. Zone 3 (ItemListEditor)
- dynamically add/remove new item
- set each item data
5. Zone 4 (ContractEditor) - all data must be flush from the editor and
persist by contractRequest.
That doesn't work for me.
How to organize my objects to accomplish my task?
Do I have to pass contractRequest to every sub-editor?
Can I use same contractRequest to persist other objects in same workflow?
Any suggestions?

Displaying Dynamic Images
Hi all,
Im trying to diaplay images(charts) on my client that I'll be
updating within some certain period at the server.
I was trying to use RPC but im new to this and im getting lots of
erros because my client cannnot find the images, probably because I
don't know how to specify the URL well. In my RPC defined the service
interface as:
@RemoteServiceRelativePath(updatePlot)
public interface UpdatePlotsService extends RemoteService {
String getImagesURL(String hostname);
}
and it's Asynchronous Interface as:
public interface UpdatePlotsServiceAsync {
void getImagesURL(String hostname,
AsyncCallbackString callback);
}
On the server-side implementation I generate a chart using JFreeChart
but Im not sure where to save it and what is the URL that i must
return to the client in order for ot to make the Image widget using
that URL.
Please Help

Re: Apache and Tomcat: Proxy, Caching and Compression configuration
Thanks. A few things: - ProxyPassReverse don't work with ajp... See: http://www.humboldt.co.uk/2009/02/the-mystery-of-proxypassreverse.html You can simple test it by performing a redirect on tomcat - Almost all browsers nowedays support gzip, so why not gzip them by default..?.. instead of gzipping them on every http request... not needed... You can tell GWT to output all your files as gzip. Then use apache httpd multiview to send the correct file. Then let apache httpd inflate the file if you encounter a browser that doesn't support gzip..(rare these days). - Use Yslow plugin for FF to fine tune your settings. - Don't forget to set the correct caching for the css, images, third party js files, etc... - Put your gwt files directly under apache httpd instead of tomcat (noserver mode). Performs much better. Only use tomcat for rpc and other backend calls.

Re: Why GWT DevMode serialization is hundred times slower than production mode?.
Well, I run my test with gwt 1.7.1 , hosted mode serialization is slower than gwt 2.03 dev mode.. Well, I finally understand that serialization of objects except than String are very slow in devmode. Therefore , I had converted previously written space efficient serialization utiliy to GWT. By means of this utility, serialization performance gain at devmode is quite satisfactory.

Re: MultiSelectionModel with CellList
Multi-selection support (ctrl and shift) was added in GWT 2.1.1, and is
enabled by default. Can you post more of your code where you initialize
CellList?
Are you aren't setting the KeyboardSelectionPolicy to BOUND_TO_SELECTION?
That will limit selection to one item at a time.

I read a lot about there being issues with selection and cells. I
just updated to 2.1.1 and hoped it would work now.
I realized that the render signature was changed in 2.1.1. Do I have

This is how my Cell looks like:

Re: CellTable: Highlight updated rows
Yes, of course. Actually, what I didn't wrote before as I wanted to keep it simple was, that I have created my own implementation of a celltable (MyCellTableT extends AbstractHasDataT) which is similar to the GWT CellTable with a couple of changes. The best way to describe what I did is to look at the source code of the GWT CellTable. In my first attempt I tried to set the background color at the end of the CellTable renderRowValues method, and I guess that didn't work because the element I got was from before the CellTable was updated with the new data. I then moved the code into the end of the replaceAllRows method in the inner Impl class of the CellTable. That is the method where the new innerhtml is set on the tbody (there is a ImplTrident class used for IE that implements this a little bit different). Now it works. Regards, Thomas.

Re: gwt mvp sessions
Hello again. It seems that I get stuck in every step... The thing is that I don´t know how to use Tomcat for the Development Mode instead of the embedded Jetty.

In my opinion it isn´t well explained at al, it´s very unclear... I have arrived to this because, as you said, protecting the host page with a servlet FORM authentication forces me to use Tomcat. So I need to check that the servlet authentication I am implementing is right. Therefore, I have to deploy my webapp in Tomcat, BUT I don´t want to end up re-deploying the application in Tomcat every time I make a little change in the code. Any help on this, please?

Test.label.setText(Image loaded.);

// Point the image at a real URL.
image.setUrl(images/kitty.jpg);
The kitty.jpg file is located in war/images folder.
The test label never shows any of the texts. Also setting breakpoints
in onLoad and onError are never reached. This means that the image is
neither loaded nor an error is raised. What can be the source of this
problem?

Simple history question
Before I delve, what's the most elegant way of handling the start page of your app? (i.e. going back to it?) Really my question is about the fact that for e.g. page2 you have created a history token with the String #page2... but when you press the back button after this, you go back to the first page that has... no token? So how do you test for this? Sorry if this sounds stupid (and I haven't done it yet)... but does the ValueChangeHandler just give you a token with an empty String () when you do this? If not, what's the most elegant way of including the first page in your history, without repeating any code, and without adding unnecessary items in the browser history? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Two parallel asynchronous rpc calls possible?
I think what you suggested, will result in Synchronous/Blocking calls. it won't be Parallel nor Asynchronous. Why not just make one call to a service and call different methods within your service object? You can put methods in your serviceImpl that are not RPC methods. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Two parallel asynchronous rpc calls possible?
Yes, it is possible, every rpc call is asyc, so if you call two rpc methods one after the other they'll be executed in parallel. In general it is better to batch the parallel methods in one rpc call.

I'm glad you qualified your comment with 'in general' which IMHO is still not true and I believe it really depends on your use case.

Re: Simple history question
Places use History mechanism behind the scenes. It is an abstraction layer which allows you to deal with History from a higher level point of view, and application oriented. in GWT applications, unlike other traditional web frameworks, we have only one .html page. therefore talking about page1, and page2,is not correct, because there is only one .html page. but to enrich user experience, making your app navigable, bookmarkable, back and forward button to work, you need to manipulate history. instead of dealing with History directly, which is low level, you use Places, as a result you can have different places in your app. HomePlace, AccountsPlace, EmployeePlace, EmployeeListPlace. and this is not just terminology differences. Places are integrated with EventBus, so as you navigate from one place, to another, PlaceChangeEvents get fired. and you can write code to handle these event changes. For example, when you have a list of employees. when you click on (select) an employee on the list, your app can take the user to a new place (employee detail place), to display detailed info on the selected employee. Please have a look at these two very well written articles on Places. GWT 2.1 Places part 1 : http://tbroyer.posterous.com/gwt-21-places GWT 2.1 Places part 2: http://tbroyer.posterous.com/gwt-21-places-part-ii Places are an integral part of GWT MVP framework, related to Activities. if you are not already using GWT MVP, I do not think there would be any benefit in using Places. only adds unnecessary complexity and huge learning curve. I do not know how what you want to do can be achieved elegantly using raw History tokens. Ryan -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: when to use AsyncDataProvider instead of CellTable.setRowData ?
I think the name DataProvider should give everyone a clue as to when and why to use one of its implementations - when you want to abstract out how data is provided to a user (meaning some sink of the data provided by the DataProvider). In addition to abstracting out how and where the data comes from, DataProviders also serve another important service. For instance, lets say you have 10 different views of the same data objects (Pojos). If you don't use a single DataProvider then all 10 views have to implement their own data providing plumbing. Instead, create a singleton dataprovider - list, async or whatever and share it among all views using the same data. Then, each view can filter on the actual instances of the Pojos it needs from the provider. Besides the benefits already mentioned, here's another one: If you provide common data through a single DataProvider then only the DataProvider has to be interested in receiving global events related to the data such as when a Pojo is updated, deleted or added and then views only need to concern themselves with redrawing themselves.

Re: App Deployment
Amazon offers many Cloud based database related solutions. Amazon RDS (Relational Database Service) is what you need. http://aws.amazon.com/rds/ Amazon RDS gives you access to the full capabilities of a familiar MySQL database. This means the code, applications, and tools you already use today with your existing MySQL databases work seamlessly with Amazon RDS. It is not free, but I believe since you are not dealing with large datasets and high volume of users, it would be an economic choice. it is on-demand, so you pay for when you actually use it. Small DB Instance is 0.11$ per hour I think along with Google AppEngine, Amazon WebServices is one of the leading cloud platforms out there. so if you gain some experience working with Amazon WS, would be a great investment and will pay off in your career.

Re: Two parallel asynchronous rpc calls possible?
Actually the benefit can be just as great when targeting traditional web servers, especially when there is high contention due to long running requests which block new requests from getting serviced. Breaking up the long running tasks into smaller atomic units of work that can run in parallel and require less cpu cycles to complete can provide a significant performance boost which users actually can experience and appreciate.

Re: RequestFactory and Client side Caching
Thank You. I looked into ProxyStore and ProxySerializer. I can see we can put individual entityproxies in ProxyStore, and later retrieve it. This is great. - do you know if it is possible to put a List of proxies in the store, and later retrieve the list as a whole, instead of an individual item, without looping through a result set ? for example, when displaying a list of data in a table, a server call, fetches a list of data. is it possible to store this list in the proxystore, without iterating through the results, and later retrieve the entire list as a whole ? - do you think ProxyStore should be application wide, bounded in Singleton scope, (similar to PlaceController, EventBus, RequestFactory) so that all of the application activities can store their data in it, and data can be available to other activities who might require the same data later on, or do you think its scope should be limited to the currently active activity(ies), and when the Activity stops, data stored within this proxystore is discarded ?

Get name=securityHandler Set name=userRealm New class=org.mortbay.jetty.security.HashUserRealm Set name=nameTest Realm/Set Set name=configSystemProperty name=jetty.home default=.//etc/realm.properties/Set /New /Set /Get /Configure And it gives me the following exception: java.io.FileNotFoundException: C:\workspace\myapp\src\main\webapp\etc\realm.properties (The system cannot find the path specified) Of course it does not find the file realm.properties. First, I have no jetty.home system variable set, and second, what would it be the value of this system variable?? The thing is, if I want to use HashUserRealm for my webapp authentication, Jetty looks for a properties file to find the users and their credentials, but where the hell is that file? Jetty is embedded... Maybe I´m wrong in something. Please help. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Apache and Tomcat: Proxy, Caching and Compression configuration
Thanks a lot for your comments. I am trying not to take static resources out of tomcat as it would make deployment slightly more complicated, but I have it in mind as soon as I run into performance issues. I am struggling a little bit with the split points: although http headers are set to expire in far future, the browser keeps reloading the split points (the .js files). I will update my posting to include your comments asap. brgds, Papick On Jan 27, 2:31 pm, Ed post2edb...@gmail.com wrote: Thanks. A few things: - ProxyPassReverse don't work with ajp... See:http://www.humboldt.co.uk/2009/02/the-mystery-of-proxypassreverse.html You can simple test it by performing a redirect on tomcat - Almost all browsers nowedays support gzip, so why not gzip them by default..?.. instead of gzipping them on every http request... not needed... You can tell GWT to output all your files as gzip. Then use apache httpd multiview to send the correct file. Then let apache httpd inflate the file if you encounter a browser that doesn't support gzip..(rare these days). - Use Yslow plugin for FF to fine tune your settings. - Don't forget to set the correct caching for the css, images, third party js files, etc... - Put your gwt files directly under apache httpd instead of tomcat (noserver mode). Performs much better. Only use tomcat for rpc and other backend calls.

Re: Simple history question

Before I delve, what's the most elegant way of handling the start page
of your app? (i.e. going back to it?)
Really my question is about the fact that for e.g. page2 you have
created a history token with the String #page2... but when you press
the back button after this, you go back to the first page that
has... no token? So how do you test for this?
Sorry if this sounds stupid (and I haven't done it yet)... but does
the ValueChangeHandler just give you a token with an empty String ()
when you do this?
Yes.
If not, what's the most elegant way of including the first page in
your history, without repeating any code, and without adding
unnecessary items in the browser history?
The easiest way is to start your ValueChangeHandler with code like:
if (historyToken.isEmpty()) {
historyToken = DEFAULT_TOKEN;
}
or to only ever associate that default page with the empty token.
This is similar to whether you'd link to /index.html (default name used by
your web server when asked for /) or / (and never ever use index.html
in your links).
I'd highly suggest you to use GWT 2.1 Places though!

Re: App Deployment
Hi Ryan, Thanks for your reply. I will keep this in mind. As the App will only be used by a couple of people, i do not think its worth investing in the hosting! However, if I become desperately stuck then I will have no option but to proceed with investment.

New to GWT, issues w/ Tutorial, Looking for Sample Project
Hi I'm Joshua in Chicago and I'm new,
The stockwatcher tutorial threw me for a loop on this bit
// Listen for keyboard events in the input box.
newSymbolTextBox.addKeyPressHandler(new KeyPressHandler() {
public void onKeyPress(KeyPressEvent event) {
if (event.getCharCode() == KeyCodes.KEY_ENTER) {
addStock();
}
}
});
I used debugging ran a search and changed KeyPressHandler to
KeyDownHandler to fix (getCharCode() was returning 0 on enter which
wasn't the 13 KeyCodes.KEY_ENTER had)
I'm going to finish the sample first but is there another good sample
on working with JSON and your own data objects, maybe w/ Google App or
Simple MySQL database?
I'm also looking to possibly contribute time to a project if you'll have me
(15 year CF, 10 .NET, 16 SQL, 14 HTML, 5ish Java fell into a .net gap
and need to brush up on AJAX and JSON)
