Re: Browser Refresh handling in GWT
To Make it more clear for everyone.
If I Implement below mentioned code in my application.
Window.addWindowClosingHandler(new Window.ClosingHandler() {
@Override
public void onWindowClosing(ClosingEvent
event) {
event.setMessage(Are you sure ?);
}
});
Window.addCloseHandler(new CloseHandlerWindow() {
@Override
public void onClose(CloseEventWindow event)
{
}
});
User is presented with a Confirmation dialog and If he says stay on
this page , then Nothing happens.
I would like to know which code can be written to have the same
behaviour without having need of any confirmation dialog.
Is there any JSNI OR any way by which we can have the same behaviour
achived wihtout any dialog.

You're problem is two fold. As already mentioned you need to be auto logging
the user back in when they refresh the page. Think about how any other ajax
app works, including the newer version of google groups. I'm logged in and
if I hit F5 I stay logged in. There has to be a session cookie and the app
checks to see if that cookie exists (then it hasn't expired) and then load
up that user's user-specific data. The user shouldn't see the log in page
again unless the cookie has expired. So make sure you know how and when the
session cookie expires. 20 minutes since last user activity is usually the
earliest a session cookie expires, but you have to choose how long it is.
Nothing wrong with having an indefinitely long session (never expires) if
the site doesn't contain highly sensitive information (banking, etc).
The next part of the problem is that you don't like it that you are losing
not only the history state (the page the user had navigated to in the web
app) but you are also losing the user specific data that is stored in JS
variables. You need to control both of these. You need your history
management to read the hash value in the URL and rebuild the site to the
page the user had been at before the page refresh. Not exactly easy to do,
but you're gonna have to get that working.
Next, you're going to have to decide how you want to maintain those
variables that are in JS. There are typically 3 options. Cookies, server
session/DB storage, or local storage. I don't know anything about local
storage, since it's pretty brand new (I know chrome supports it, but I don't
know what other browsers do, if any (the others probably do or will soon)).
Cookies are easy and not a bad option depending on the usage. You could use
them as temporary storage so that refreshing the page wouldn't kill all the
work done by the user. But you'd need to be sure you don't leave any cookies
lying around as the user navigates the app. Each page of your app could
store values entered in cookies until they click the Save/Cancel button, at
which point you delete the cookies. Make sure you delete those cookies when
the user simply navigates away to another page on your app. Remember,
cookies are sent along with any and all server requests, so if you've got
200 cookies, they are all going to go on the ride on a simple RPC and
seriously increase traffic latency.
The most common solution is storing the values on the server. You can easily
RPC user entered data to the server between user entries with tons of time
to spare. User input is so slow compared to simple RPC service requests. The
same idea as saving and deleting cookies applies here. It's just temporary
session data that shouldn't persist between pages otherwise it's a waste
of memory. Although, it's a pretty good idea to basically do away with the
Save button by simply saving the user entered data straight away to the
server DB, rather than just saving it as temporary session data. Then you
don't even have to worry about managing the temporary data. This is what I
highly recommend. But it depends on the app and what you are trying to
accomplish.
Lastly, I do know of a fool proof way to prevent any attempts to leave the
website you are on, including refreshes or even changing the URL in the
address bar. However this is BAD and you most definitely should NOT be doing
that in your scenario. You need to implement something along the lines of
what I've already said, because that's how everyone else does it.

Juniper IVE fails to rewrite ClientBundle CSS urls in FF and Chrome
Hi
We have found a bug in Juniper IVE (Instant Virtual Extranet).
Although it's a bug that should be fixed by Juniper I would like to
share with you the problem so you know about it before you believe
that a GWT application can be published in Juniper or maybe you can
suggest a work around.
An application using GWT 2.0.3 with CSS in a ClientBundle has CSS
rules that include images as background.
When accessing the application from the Internet a Juniper SA-4000
version 6.5R8 rewrites all URLs and gives access to the internal
server, for example:
Real URL:
http://privateserver.domain.com/img/logo.gif
Rewritten URL:
../img/,DanaInfo=privateserver.domain.com+logo.gif
Some kind of client side software (js or a plugin) is used by Juniper
on the browser to capture all those rewritten URLs and send them to
the Juniper appliance, then go to the internal server, get the
resource and send it back to the client.
Rewriting JS and URLs is tricky and Juniper often releases patches to
solve problems, I don't like the Juniper approach to publish websites
but it's used in many big corporate networks.
The problem:
URLs are not rewritten in the CSS rules that are part of a
ClientBundle in Firefox or Chrome as it does in Internet Explorer.
Example:
In CCS;
@external sesion;
#sesion{
background-image: url(img/sesion.gif);
background-repeat: no-repeat;
}
In Internet Explorer, the URL for the image is rewritten:
#sesion{
background-image:
url(../img/,DanaInfo=privateserver.domain.com
+sesion.gif);
background-repeat: no-repeat;
}
In Firefox or Chrome the URL for the image is not rewritten:
#sesion{
background-image: url(img/sesion.gif);
background-repeat: no-repeat;
}
We will apply a temporary solution: include another CSS that is not
part of a ClientBundle with all rules that have urls, that way Juniper
can translate the URLs.
If you have any other solutions please let me know.
Thanks
Javier

Re: Error installing GWT 2.2 in eclipse 3.6
As I mentioned in my first post, my development machine sits behind a corporate firewall. In the past, this has not been a problem as certain exceptions are in place for when we use the GWT update site. For GWT 2.2 however, the firewall still seems to catch the files I listed, even though the rest of them download fine. After some investigation, it would seem that update files are usually served from... http://commondatastorage.googleapis.com whereas the files which were failing were being served from... http://v22.lscache1.c.bigcache.googleapis.com Furthermore, the redicrection changes over time, googlehosted. 1.google.com was metioned by our team. What I would appreciate, and I suspect I speak for all enterprise users of the GWT Eclipse update service when I say this, would be a list of firewall exceptions (updated from version to version) to allow us to better inform our techincal services providers of any required changes prior to running into this kind of issue. Perhaps, these cases of people making changes (deleting plugins, installing on a different day etc.) and having success are actually the result of the URL redirections chaging over time? If that is the case, the exception info is even more vital. At the moment, we cannot use the update facility, because it is impossible for us to know what IPs to allow. Thanks for your support, Andrew Scully.

Re: More than one hostpage, each with an own entryPoint
Take a look at gwt-multipage (http://code.google.com/p/gwt-multipage/). It allows you to annotate entry points to be invoked based on either a URL pattern or a token stored in a javascript variable. It also uses GWT.runAsync() to download only the entry point to run on that page. One warning... the current build is not yet compatible with the recently released GWT 2.2. It runs into the same backwards compatibility problem that various other libraries (including GIN) are having right now. I'm not sure when we'll be able to address this, but if you absolutely need to use GWT 2.2, you can download the source, change GWT version in the POM to 2.2.0, and build it yourself without further changes. -Brian On Thu, Feb 17, 2011 at 4:22 AM, frank t3devt...@googlemail.com wrote: Is that possible?

Then create, for example a new JSP file called MyModule.jsp and copy from your recently created hosted page (.html) the script tag to include the GWT generated js. I hope this helps you. PS: And if you need to share some classes you can create a module without an entry point and then in your other Module Descriptors inherits this module with this tag: inherits name='com.mycompany.myapp.mymodule.Mymodule'/ -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: exception translation
I am getting a StatusCodeException. May I am a bit more specific: I
have to check concurrency problems. In case of a concurrency the GUI
has to show a user dialog. The StatusCodeException just give me the
ErrorCode 500 (Internal Server Error) but this is to unspecific. This
error code can occour in other cases as well so that I need another
identifier.
The original exception is capsulated in the message body of the
StatusCodeException with HTML tags. A dirty solution would be to make
a String RegEx and search for a pattern which identify the concurreny
exception in the exception message. But there must be a more elegant
way of doing this?!
So how can I do this better without an RegEx or string search?
This would be the message of the StatusCodeException:

Re: GWT 2.2 Eclipse update fails -- needs PDE
This is a well known and widely reported general problem with Eclipse 3.4 that has been fixed in newer versions of Eclipse. The problem is with Eclipse p2 and not with GWT 2.2 itself. If p2 is complaining about the Eclipse PDE, you can try installing that manually from the Eclipse update site. GWT/GPE 2.2 does require the PDE (which is a standard part of the Eclipse SDK) but does not prereq any specific version so the exact error message is being triggered by Eclipse and not GWT/GPE. -Eric On Feb 17, 5:01 am, francescoNemesi nem...@yahoo.com wrote: I have the same problem, but I must use 3.4 for compatibility with other plugins... could you please investigate and fix?

If so, the opponents clock starts, and your clock stops when you trigger the clock's actuator, not ... when he or she makes a move. Your clock stops and the opponents clock starts when you end your move, not when you start. you can see the timer counting 1:01, 1:02 Which uses a GWT animation technique. This would be the guessed elapsed time I agree that there will be a latency here. That's the nature of the network beast. I suppose you could advance the clock based on measured latency, but you can correct for this on receipt of the opponent's actual elapsed time. and then get the message from the server the opponent made a move at 1:00, and the client have to correct the time. It's elapsed time, not wall time. If chess players cared about wall time, then chess games via snail mail wouldn't be very much fun. Each player sends an elapsed time message to the server upon the digital equivalent of the analog hit of their stop switch on the clock. The client sends a message to the server that contains the actual elapsed time. I do agree that a correction must be made on each player's clock for differences in the opponent's actual vs. guessed elapsed time. The local display is corrected upon receipt of an elapsed time message. Synchronize the time with the server can be made for example: 1. client sends a request to the server to get the server time, and records the sending time of the request (1:01.5) 2. the server sends back the server time (0:59.3) 3. the client gets the time and records the time of getting the response (1:03.1) Now the client can estimate the network latency by getting the difference of the 1. and 3. step and dividing by 2. (1:03.1-1:01.5) / 2 = 0:01.6 / 2 = 0:00.8 The latency has to be added to the server time sent by the server and you are ready. (0:59.3 + 0:00.8 = 1:00.1) This works if the server is not too busy and the response is generated immediately.

I need help especially for these questions: - How do I realize the running clock? Do I have to a timer every second, update the display and create a new timer? - As a starting point, the client receives some initial time value, e. g. when a game is loaded, the client receives the information that black has already spent 01:00 (1 hour).

However, when the client starts counting, the time may already be at 01:03, depending on the bandwidth of the internet connection. Can one do something about this? Isn't this chess clock an elapsed time clock? In other words, the clock doesn't sync with wall time, or with the server. It doesn't even have to take time zone into consideration.

Re: How about do the UI in the Java-Swing way?
1) About accessibility : A Button, which implemented in the way i imagined, would produce a div tag as well as a canvas tag. Both tags occupy the same position, but the div tag is on the top of the canvas tag. So, the div tag takes the responsibility for accessibility. 2) Everything (focus management, event handling, etc.) is still under browser's control. Each widget has its own canvas, not a universal shared one. You press Tab, and the focus jumps from button1 to button2.

Re: How about do the UI in the Java-Swing way?
CSS was hard for me at first too, but now that I've gotten a good hang of it, I really prefer it to trying to do the styling in code. Especially with GWT's enhanced css capibilities (conditional styles based on user.agent/locale). Not to mention with tools like firebug, it is pretty quick to go through and debug and experiment with styles. I get that this isn't addressing the issue you brought up, but I've found learning CSS to be an extraordinarily useful and well worth the effort to pick up. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How about do the UI in the Java-Swing way?
You can achieve all that with css. Some parts are tricky without css3, like shadow or rounded corners, but its still possible. Imho the browser is already a quite good rendering engine and you get accessibility. I would rather like a gwt-only, good looking, clean and open sourced set of html/css widgets, which supports the most use cases. Also it should support themes and easy configuration. At the moment there are only dual licensed solutions out there like smartgwt or extjs.

I have an editor that uses a ValueBoxBaseLong to store a very large number.

Basically, when I set value 6920835985627925836 and then immediately get the
value, it returns 6920835985627925504 .
The value shows up properly in the editor itself, but when getValue is
called, the wrong value comes back.
I think the problem is in LongParser
(http://google-web-toolkit.googlecode.com/svn/trunk/user/src/com/google/gwt/text/client/LongParser.java):
public Long parse(CharSequence object) throws ParseException {
if (.equals(object.toString())) {
return null;
}
try {
return (long) NumberFormat.getDecimalFormat().parse(object.toString());
} catch (NumberFormatException e) {
throw new ParseException(e.getMessage(), 0);
}
}
In this case, parse returns a double, which is then cast to a long. I think
this is chopping a couple bits of precision off of my Long, causing the
mutation.
Can anyone verify if this is correct or not, and if there is an Editor widget
that can support the full range on a Long ? (This is in GWT 2.2)

Re: Feedback Requested: Preview of new GWT Style Theme
Here's my feedback. Sorry it's so long. I have quite a few comments about the tendency toward using various blue colors. I'm not entirely against that, but I think the blues should be consistent. That said, I'd rather have no color and be able to easily add color if desired. That way, the default style won't clash with anything around it. To put it another way, the default should be that you don't have to change anything to avoid an ugly UI. Basic Button: I don't think that disabled buttons should change on hover. In fact, disabled Custom Buttons don't seem to change. They should at least be consistent (and, being disabled, I think they shouldn't react to the mouse at all). Date Picker: Nice. I don't mind the use of blue here, but it would be good to be able to easily customize that. The only thing I don't like is the dark gray bold text. It makes the text look hazy and harder to read than it needs to be. When other text on the page defaults to black, I think the dark gray looks out of place. Suggest Box: I agree with Chi Hoang about removing the rounded corners from at least the top of the suggestion box. Also, the positioning overlaps with the focus highlighting of the textbox in Safari and Chrome, at least on Mac OS X, and looks sloppy. Finally, something looks funny about the bold font to me (across all browsers on Mac OS X). For example, lowercase a does not look smooth. I know this isn't exactly the fault of GWT, but maybe a different font selection or a different way of achieving the font will make it look better... but I'm no expert with CSS fonts. Tree: I don't like the +/- icons at all. They're small, positioned slightly high relative to the text, and don't really need the blue coloring either. Also, they aren't consistent with Disclosure Panel (see comments below). Menu Bar: I think this style looks a little out of place. Like the Suggest Box, maybe the bottom should have rounded corners but be squared off at the top. Either way, I'm not a fan of the drop shadow. It's very inconsistent with other panels, especially Basic Popup and Dialog Box (which both look very nice). I also think the subtle color is out of place. The gray color and progression of the gradient used for buttons is much nicer and would be equally nice for menus. Stack Panel: This uses rounded corners on the top but is squared off at the bottom, which is again inconsistent with other panels. I don't like the rounded corners because, when you switch focus from Mail to Filters, the straight gray line under Mail changes to a curved line and the background flows further down into the new space that the curve creates in the Mail tab. I'm not sure what the metaphor would be in the physical world, but something about that shift feels wrong. Finally, I don't think the blue gradient fits and is different from the blue used for Menu Bar. If you're insistent on using blues, they should at least be consistent among the components. Basic Text: Not bad, but the top border color is a little dark compared to the side/bottom... or maybe the side/bottom color is a little light. Rich Text uses #bbb instead of #ccc... maybe that would look better here. Rich Text: Nice. Good that the tool buttons are consistent with Basic Button. However, it looks like the blue gradient for the toolbar is the same as was used for Menu Bar, so my comments on that apply here, too. Disclosure Panel: I'm not sure the left border is necessary, and it looks funny because it doesn't line up with the tip of the disclosure arrow. However, I'm also not a fan of the disclosure arrow. I think it's a bit large (compare with Mac OS X Finder, which it seems to be heavily influenced by), the anti-aliasing isn't very crisp (which may actually be what's making it feel a little big), and it sits a little too high relative to the text. Also, I think it's odd that the same element isn't used for both Tree and Disclosure Panel. Tab Layout Panel: I like the concept much better than what we have now. Like others, though, I agree that the blue is a bit striking for the default style. Also, why no gradient? I actually like it without, but it isn't consistent with Menu Bar and Stack Panel. Also, I don't like the dark gray text on the active tab for the same reason as I don't like it for Date Picker... though I understand the reason for using bold text in this case. Cell Table: The headers look bad. Dark gray text (though slightly lighter than used in other places) and a blue shadow just doesn't work for me. At the very least, get rid of the shadow. Also, the buttons for the pager being circular buttons seem out of place. I'd rather something styled like the month switching buttons in Date Picker. Cell Browser: The arrows _very_ jagged. Also, the gray gradient for the selection seems much too dark and too steep of a gradient. Overall, I like many elements of the new theme, as well as the goal of not changing the DOM to achieve it. I would use this theme in any new applications and

+1 for me. IE support is still important, but I don't see how the final user gets benefit from emulated roundedCorners/shadows/gradients when he probably only using IE (so he will never tell the difference) and the extra markup ends up slowing down the app. This problem gets ever worst when the implementation for IE is used on the other browsers to get consistency (i.e the old DecoratorPanel or the DialogPanel).

Re: Feedback Requested: Preview of new GWT Style Theme
FWIW, IE9 also supports rounded corners. The TabLayoutPanel formatting has some good improvements, but the solid blue band across the top is a bit intense. I'd maybe lose it, round the tabs, and use a slightly more muted color for the tab background colour. If the tabs were formatted exactly like the stack panel items, I think they would look quite nice. http://gwt-showcase-clean.appspot.com/#!CwTabLayoutPanel http://gwt-showcase-clean.appspot.com/#!CwStackPanel On Feb 17, 8:08 am, John LaBanca jlaba...@google.com wrote: Chrome, Safari, and Firefox support rounded corners natively in CSS.

Re: how to realize a realtime clock running in the client?
The server is what's in common and must be the keeper of time. If you're worried about latency making timings inaccurate, there are much bigger potential problems with making the clients keep track of time. For example, assuming you have some unique token for that match on the URL, what happens if the user refreshes the browser? Everything happens on the server at the time that the server is told about it. The server can then report current elapsed times, time stamps for certain actions, or anything else that you need to display to the user. On the client side, you can ask the server about the elapsed time and present a view that approximates a real-time clock that matches. These may drift due to latency or other factors, but can be synched periodically (when other actions happen, once per minute, or whatever is appropriate). Now, if that isn't accurate enough, you can start thinking about improving it by trying to measure latency or using other tricks. The important point is that reality resides on the server. The UI will eventually show an accurate picture of that reality. It should be pretty easy to make the view accurate to a few seconds. If that's not good enough, a little extra work (measuring latency) should get accuracy down to less than a second. I don't play chess enough to know, but I imagine that's good enough for this case. -Brian On Thu, Feb 17, 2011 at 10:10 AM, Jeff Chimene jchim...@gmail.com wrote: On Thu, Feb 17, 2011 at 12:57 AM, János Kiss ffun...@gmail.com wrote: If the timers run only on the clients, it can be inconvenient if they are'nt synchronized.

Your clock stops and the opponents clock starts when you end your move, not when you start. you can see the timer counting 1:01, 1:02 Which uses a GWT animation technique. This would be the guessed elapsed time I agree that there will be a latency here. That's the nature of the network beast. I suppose you could advance the clock based on measured latency, but you can correct for this on receipt of the opponent's actual elapsed time. and then get the message from the server the opponent made a move at 1:00, and the client have to correct the time. It's elapsed time, not wall time. If chess players cared about wall time, then chess games via snail mail wouldn't be very much fun. Each player sends an elapsed time message to the server upon the digital equivalent of the analog hit of their stop switch on the clock. The client sends a message to the server that contains the actual elapsed time. I do agree that a correction must be made on each player's clock for differences in the opponent's actual vs. guessed elapsed time. The local display is corrected upon receipt of an elapsed time message. Synchronize the time with the server can be made for example: 1. client sends a request to the server to get the server time, and records the sending time of the request (1:01.5) 2. the server sends back the server time (0:59.3) 3. the client gets the time and records the time of getting the response (1:03.1) Now the client can estimate the network latency by getting the difference of the 1. and 3. step and dividing by 2. (1:03.1-1:01.5) / 2 = 0:01.6 / 2 = 0:00.8 The latency has to be added to the server time sent by the server and you are ready. (0:59.3 + 0:00.8 = 1:00.1) This works if the server is not too busy and the response is generated immediately.

Change Cell style inside CellTree using SelectionModel
Hi, guys. Sorry, but I could not find an answer here, and still could not figure it out the proper way :-( So, please, give me some hints, about how it is supposed to be done. Lets take Showcase CellTree example, when clicking on a node - node is highlighted with yellow color, but when clicking outside CellTree widget that highlighting disappears, and nothing now tells us which node is selected. So I am looking at the proper way to highlight node permanently - so even when focus lost - node is still selected. In other words, is there a way to change style/rendering for a Cell inside CellTree using SelectionModel? So when SelectionModel has some node's values that node's cells rendered in different style. Should it be done inside TreeModel when providing nodes, by say, checking if node is selected and supplying special cell, with different style, for such a node? I guess not. I would not bother, but obviously there is some kind of mechanism already (those yellow and blue styles), but I couldn't figure it out how to use it.

Re: Feedback Requested: Preview of new GWT Style Theme
I would support just using border-radius for rounded corners and living with square corners in IE 6-8. (Same with using box-shadow for shadows, e.g.: in DialogBox) I think it still needs to look 'good' on IE6-8, but it doesn't need to look exactly the same, and i think missing rounded corners is an acceptable difference. If you are going to take that approach, I think you should also break a bit of backwards compatibility with the new theme by changing the DOM structure of some of the existing widgets. Using border-radius and still having superfluous 3x3 tables all over the place seems like a decision that will be regretted down the road. Internally, we have an internal implementation for buttons and tabs that, via deferred binding, uses border-radius on HTML5 browsers, and images for rounded corners on IE6-8. That is not the easiest thing to implement (and we didn't try to make it generically theme-able), but would be my 'ideal' solution for the widgets where that is possible.

RegExp not matching, but it should
I have the following regular expression:

The intent is to match filenames for image files. (e.g.
myimagefilename.jpg).
my code to set this up is below. When I step through it I find the
following:
1. The regular expression looks valid, meaning at runtime the
IMAGE_FILE_PATTERN has proper javascript form: /\S*\.(jpg|png|gif|bmp)$/gi
2. The following filename - DSC_0001.JPG evaluates to false when tested

Re: Feedback Requested: Preview of new GWT Style Theme
Another nice aspect of border-radius over the emulation approach, is that it lets you avoid aliasing artifacts when changing the page size via full-page zoom. For example, if you look at the basic popup on the showcase, and change the page zoom size in your browser, you can see occasional single-pixel 'cracks', and the rounded corner ends up being pixelated. On Feb 17, 11:37 am, Chi H c...@chi.ca wrote: I would support just using border-radius for rounded corners and living with square corners in IE 6-8. (Same with using box-shadow for shadows, e.g.: in DialogBox) I think it still needs to look 'good' on IE6-8, but it doesn't need to look exactly the same, and i think missing rounded corners is an acceptable difference. If you are going to take that approach, I think you should also break a bit of backwards compatibility with the new theme by changing the DOM structure of some of the existing widgets. Using border-radius and still having superfluous 3x3 tables all over the place seems like a decision that will be regretted down the road. Internally, we have an internal implementation for buttons and tabs that, via deferred binding, uses border-radius on HTML5 browsers, and images for rounded corners on IE6-8. That is not the easiest thing to implement (and we didn't try to make it generically theme-able), but would be my 'ideal' solution for the widgets where that is possible. That being said, there are much higher things on my wishlist than that :) On Feb 17, 9:08 am, John LaBanca jlaba...@google.com wrote: Chrome, Safari, and Firefox support rounded corners natively in CSS.

CellTable slow in IE 8
Hello, My CellTable seems really slow in Internet Explorer 8. It looks like the row highlighter can't keep up with the mouseover (even if there are only 10 records in the table).

Re: CellTable slow in IE 8
One common cause of slow hovering performance is the use of descendant CSS
selectors in your CSS files.
This is bad:
.myForm td {
padding: 3px;
}
This is good:
.myCell {
padding: 3px;
}
When you use the first version, the browser matches the second part td to
EVERY TD element on the page. It then walks up the DOM looking for a parent
element with .myForm. For a large app, especially one with a large table,
most TD elements are not part of .myForm and you end up with a degenerate
case where you walk up to the body element. So, each time you hover over a
row, you have 100s of DOM walks to slow down your app. Avoid using
descendent selectors where the child is a common element.

Only the last line is taken into account here.

UiBinder problem with IsWidget
Hallo,
I basically have a Widget interface MapWidgetK,V which provides Map-
Methods K - V and extends IsWidget.
If I put it in my template like this:
h:MapWidget ui:field=map/h:MapWidget
And put in my respective owner class
public class Blubb {
interface MyBinder extends UiBinderMapWidgetString,String, Blubb{}
MyBinder binder = GWT.create(MyBinder.class);
@UiField(provided = true)
MapWidgetK,V map;
public Blubb(MapWidgetImplementation widget){
map = widget;
binder.createAndBindUi(this);
}
}
I get an Exception that MapWidget should not be abstract (Exception
while binding)
But shouldn't this work, as long as I have (provided = true) and
acually pass in a concrete Implementation that extends Composite???
I hope someone can clarify this for me :-)
Greetings,
Pete

No, you always get the Confirmation dialog. Read my post carefully. I describe the correct way of doing this. You should NOT be preventing the user from leaving the page!

Your gwt code simply needs to check to see if they have already logged in and then decide to NOT display the login page and instead build the site according to the History token.

Re: Production bugs that don't exist in development mode
You aren't understanding the issue properly. The callback method you just
mentioned is the onSuccess() method that you override. The issue is when
that method is being called. In production the onSuccess() method is
actually being deferred (the word I should have been using) until after
the currently running JS has been completed. In dev mode the onSuccess()
method is being called immediately, aka inline with the code that calls
GWT.runAsync().
Try this code yourself if you don't believe me (note I wrote this code here
and has not been checked for compilation errors... at the least it's missing
the onFailure() method):
code
public void createAsyncPage(){
final String myString = null;
GWT.runAsync(){
public void onSuccess() {
myString = GWT is the best!;//this code is ran later in production,
but runs immediately in dev mode
}
}
myString.contains(GWT);//this should be a bug, this should result in a null
pointer exception!
//It will be null in production, but not in dev mode!
}
/code
Someone has already responded to the GWT issue I created and has noted that
this inconsistency has actually been documented in the GWT code with a TODO to
fix it.

Re: SuggestBox can't set Oracle
IIRC it's a relatively recent change in GWT and I cursed a little when I
encountered it. I solved it by instantiating the SuggestBox using the
3-parameter constructor that let you specify an oracle. Using UiBinder and
gin to inject my SuggestOracle this gives:
public class MyView {
...
@UiField(provided = true) SuggestBox suggestBox;
private DefaultSuggestionDisplay suggestionDisplay = new
DefaultSuggestionDisplay();
private TextBox suggestTextBox = new TextBox();
@Inject
public MyView(ClientSuggestOracle clientSuggestOracle, ... ) {
clientBox = new SuggestBox( clientSuggestOracle, clientTextBox,
suggestionDisplay );
}
}

Re: Production bugs that don't exist in development mode
Fair point, Ben. The onSuccess() method is where we are creating the async objects and no other code *should* be interacting with those objects elsewhere. However, other objects that needed to exist on page load, long before async code gets loaded, do need to interact with objects that are created asynchronously (but only once they have actually been created). So those objects can't attempt interacting with those objects if they are null. So it is indeed a developer's bug to not be checking for null. The issue here is that in dev mode you won't catch those bugs and when you encounter them in production mode you can't easily determine where the code is breaking. Does that make sense? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group. To post to this group, send email to google-web-toolkit@googlegroups.com.

Re: Production bugs that don't exist in development mode
Again, you can probably argue that a better design would have it so that the already existing objects should be waiting for the async objects to inform them of their creation. Ultimately you are still checking for null and designing it that way it's obvious that you have to check for null. But a lot of the code written might not have been planned for something to be created asynchronously and so it just assumes it was created earlier. But when the createPage() method is changed to have a GWT.runAsync() inside it, that suddenly changes things and introduces this problem. We just need dev mode to behave correctly so us developers can realize we either need to check for null or change our design.

RequestFactory/Editor AutoBean has been frozen error
I am trying to use the RequestFactory and Editor frameworks together. I have it working successfully for requests that finish successfully or that result in constraint violations. However, whenever there are server errors and my Receiver.onFailure(ServerFailure) method is called I am not able to reuse my proxy object. If I do nothing in the onFailure method other that setting the some error message in the ui and then try to fire another request using the same proxy object I get the AutoBean has been frozen error message. When there are contraint violations I can successfully fire another request with the same proxy object. After digging into the code I found the doFire method in AbstractRequestContext. Inside this method it creates an anonymous TransportReceiver object which handles the response from the server. TransportReceiver.onTransportSuccess(String payload) handles an response that successfully hit the server. If response.getGeneralFailure() != null or there are constraint violations AbstractRequestContext.reuse() is eventually called which unfreeze any autobean entities that were apart of the request and unlocked the request context. However on errors that aren't generalFailures reuse() is never called. This means that this instance of the autobean can never be used again without getting the Autobean is frozen error. Has anyone else run into this issue. If so is there a workaround for it. Thanks -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: CellTable slow in IE 8
Thank you for your responses. Looking through the CSS, we DON'T have
any descendant CSS selectors.
However, I DO see the same performance degradation in IE 8 on the
cellTable showcase sample here:
http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellTable. So
it does seem to be a problem with my environment/browser and not my
implementation.
What's weird is that the row highlighter keeps up great with FireFox,
it seems to just be a problem with IE 8 on a Windows 7 machine. Other
people here running IE 8 on windows XP did NOT see the slowdown. It
seems to be very much browser dependent.
At this point I'm thinking it's yet another weird thing about Internet
Explorer. I'm not sure there's anything I can do at this point, save
for upgrading to GWT 2.2.
Thanks for your help!

One common cause of slow hovering performance is the use of descendant CSS
selectors in your CSS files.
This is bad:
.myForm td {
padding: 3px;
}
This is good:
.myCell {
padding: 3px;
}
When you use the first version, the browser matches the second part td to
EVERY TD element on the page. It then walks up the DOM looking for a parent
element with .myForm. For a large app, especially one with a large table,
most TD elements are not part of .myForm and you end up with a degenerate
case where you walk up to the body element. So, each time you hover over a
row, you have 100s of DOM walks to slow down your app. Avoid using
descendent selectors where the child is a common element.

Hello,
My CellTable seems really slow in Internet Explorer 8. It looks like
the row highlighter can't keep up with the mouseover (even if there
are only 10 records in the table). With longer tables it makes
scrolling down the page seem laggy. I don't seem to have this problem
in FireFox 3.6.
Has anyone else run into this problem? I've read this thread but found
no solution:
http://www.devcomments.com/My-CellTable-is-slow-and-I-don-t-know-why-...
Has anyone else had problems with IE and slow CellTables being slow?
Hoping for some tweak that could speed it up. Alternatively, is there
a way to disable row highlighting? I removed the styles from the .css,
and although it takes away the highlight itself, the CPU still gets
eaten up and the table scroll lags.
Any input is *greatly* appreciated.
Thanks so much,
Pedro

[gwt-contrib] Future of CellTable
Hi, first of all congrats on the new 2.2 release!

I'm still waiting for a good time to get rid of the incubator and port our apps... Daniel -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
Re: [gwt-contrib] Future of CellTable
We plan to add the following features the CellTable: - Fixed headers/footers with scrollable content area (hopefully for GWT 2.3) - Formalized inline cell editors (maybe GWT 2.3) - Expandable rows (really, a fully customizable table builder, probably post GWT 2.3) After that, we haven't decided which new features to add. Certainly there are tons of features we could add, but we'll have to weigh them against other efforts, such as general mobile support. As far as user column resizing goes, it isn't on our agenda at the moment and is probably a lower priority than other features.

That would benefit from an asm based signature that only looks at api level structurePerhaps this present code could be modified to alternately accept a flag to consider annotations as well, if desired. I'm wondering if handling the case where some methods have been re-ordered in a source file is worth incurring the overhead of sorting and managing multiple StringBuilders, etc. This could add up if we have a large number of classes to consider, etc. I'm not sure how often a source file has some fields/methods re-ordered, vs. other api changing edits, or how important it is to seamlessly handle that case (I think the user expects some recompiling when editing code). Maybe it's not too expensive though (in which case I'll go jump off a cliff)? How long on average does it take to generate a signature with this code? I think that should be a design consideration too. Eric, do you have any timing numbers on that? I've been thinking along the same lines, that we should have a good way to compute for typeoracle. I haven't done any performance measurements.

Currently, we have a dumbed down version of generating a signature from the full bytecode (in JRealClassType). That would benefit from an asm based signature that only looks at api level structurePerhaps this present code could be modified to alternately accept a flag to consider annotations as well, if desired. I have to agree that this should be separate. For example, TypeOracle cares about parameter names, annotations, etc; none of which would force recompile propagation. I'm wondering if handling the case where some methods have been re-ordered in a source file is worth incurring the overhead of sorting and managing multiple StringBuilders, etc. This could add up if we have a large number of classes to consider, etc. I'm not sure how often a source file has some fields/methods re-ordered, vs. other api changing edits, or how important it is to seamlessly handle that case (I think the user expects some recompiling when editing code). Maybe it's not too expensive though (in which case I'll go jump off a cliff)? I'm sure it's not terribly expensive, and I'm generally not a fan of trying to micro optimize on the front end. If it becomes a source of sluggishness, it'll show up on profiling at some point. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
