Re: Failed to get SerializationPolicy when Web Application contains encoded dash
Is there anything I might have missed here?
I can't imagine nobody of you experts stumbled over such problem so far.

Re: I'm enhancing GWT to provide Java stack traces for clientside exceptions in production
Thanks for all your questions. Here are my answers. So, something like this has been used at least internally for quite a long > time -- what exactly did you have to change in StackTraceDeobfuscator? > Quite a few things, actually. I go into great detail about that, including diffs of some stack traces, in my paper: http://goo.gl/YGsrQ In short, my solution is prettier, more efficient, and more accurate than what you've been using. I'm not sure that's going to be worth using in a performance-sensitive > application. Also, how much does this affect compilation time? Performance was critical to my application as well, and that's why I put in a lot of extra effort to make my solution almost 50% more efficient than my predecessor's work. I'm already using it in production on typeracer.com. You can visit my site and see that it's very fast. The impact on compilation time is negligible (less than 1 second per permutation). Do you plan to maintain that code if it is integrated into GWT or will it > be a one time contribution and other people have to wrap their head around > it again if your solution needs to be adjusted? > Yes, I will maintain the code regardless, even if it doesn't get integrated into GWT, because my app is already using it in production, and I consider it of high importance to my business. If my project gets funded, then I will work on integrating it into GWT and maintaining that code thereafter. Otherwise, if there's not enough interest from the community, I'm not sure I'll bother integrating it. Either way, my work is pretty self-contained and only touches a handful of existing classes: JsStackEmulator, StackTraceDeobfuscator, and StackTraceCreator. > I ask this because GWT will drop support for IE6/7 relatively soon and > probably by the end of 2014 drop support for IE8.

That said, right now, only one browser supports SourceMaps-based stack traces. Let me be clear: my project is not about just any one solution, like stack emulation or SourceMaps: it's to make perfect Java stack traces available in any browser that can run your GWT app. My code lays the foundation to make that happen with minimal future effort, even as browsers evolve. > So by the end of next year a bunch of your code can probably be deleted > and other code refactored/optimized to fit this situation. Have you thought > about that? I don't think any of my code will have to be deleted. I've introduced a selection property that selects whether the browser supports the SourceMaps-based stack traces or not, and introduces stack emulation only if needed. Otherwise, it uses the SourceMaps-optimized solution, which carries no overhead. What sort of approach does the current emulated stack implementation use, > as opposed to the suggested function enter/exit approach? Is there a > relative speed hit involved with it too? My approach to stack emulation is the same as before, just more accurate and more optimized. The cool thing is that in Chrome and any future browsers which provide both line and column numbers in Javascript stack traces, my code will give you perfect equivalent Java stack traces with absolutely no performance penalty (you can read about how it works in my paper: http://goo.gl/YGsrQ ) Because if so, bring on the new implementation ASAP :) I'm hoping to! Please consider making a donation and spread the word about my campaign: http://igg.me/at/gwt-stack-traces/x/3494291 :) Thanks guys. Any other questions?

Re: I'm enhancing GWT to provide Java stack traces for clientside exceptions in production
Do you plan to maintain that code if it is integrated into GWT or will it be a one time contribution and other people have to wrap their head around it again if your solution needs to be adjusted? I ask this because GWT will drop support for IE6/7 relatively soon and probably by the end of 2014 drop support for IE8. Also Opera has switched to Blink/V8 which makes the opera permutation obsolete in the near future. So by the end of 2014 (GWT 3.x) Firefox, Safari, Chrome and Opera are likely to support SourceMaps and in case of IE9+ stack trace emulation is probably not needed. So by the end of next year a bunch of your code can probably be deleted and other code refactored/optimized to fit this situation. Have you thought about that? -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: No source code is available for... did you forget to inherit a required module?
You either have to bundle source files into your library jar or you have to create a second jar containing only source files and put this extra jar also on classpath in your IDE (not attached to a jar, I think it must be a class path entry on its own) and in your ANT script. Finally if your library jar contains source files in folders that are not already included through an existing *.gwt.xml file, you would need to create a new *.gwt.xml containing the additional information and bundle it into your source jar. Example: Project: com/example/app/ client shared server App.gwt.xml (contains and . Also contains ) generated-utils-sources.jar (on classpath in IDE and in ANT script) com/example/app shared //lots of source files (no *.gwt.xml needed as App.gwt.xml already contains ) dtos //lots of DTO source files GeneratedDtos.gwt.xml (contains . You could also move that file one level up and then have . Just personal preference.) P.S.: You don't need and as the first already includes everything. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

No source code is available for... did you forget to inherit a required module?
Ok so I have read alot of these threads but I am very new to eclipse, GWT, XSD, and jaxb. Sooo, I have come across this when doing an ANT build. I have a JAR file that has my .class files and attached the source code via configure build path menu. I have tried putting the JAR file inside my client source folder, outside of it, both, and inside a resources folder inside the client folder. I have , , in the gwt.xml file. Have also tried: http://www.vogella.com/articles/GWTModules/article.html and http://markmail.org/message/h52xvo4j52msambe#query:+page:1+mid:lg4mlgiof4giuiaq+state:results We had a workaround where we created a package inside the project within the shared folder containing the .java files for the JAR. However we would like to use the JAR with the .class files created from the XSD. Any help is greatly appreciated. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT request factory - Fire request inside of success method of another request
Assuming you removed the extra GWT.create (as Thomas mentioned on
stackoverflow).. if might be worth trying putting the second call inside a
Scheduler.get().scheduleFinally...
Seems odd. I'm sure we do this sort of thing (less directly) all the time.

Re: GWT request factory - Fire request inside of success method of another request
You mean renaming the inner request method? I tried that -> doesn't change
anything.
It is not only in prod mode. It's a GWT test case that I run locally.

Changing the Displayed Value in a DataGrid
I am trying to modify the value that is displayed in a DataGrid cell after
the user has entered or modified the existing value. For example, if the
user enters "5/6/12" I want the cell to display "05/06/2012" when the user
exits the cell. Here is the code that creates the column:
final TextInputCell fosterDateStartCell = new TextInputCell();
final Column fosterDateStartColumn;
fosterDateStartColumn = new Column(fosterDateStartCell) {
@Override
public String getValue(final IFosterHistoryProxy fosterHistory) {
final String date = fosterHistory.getFosterDateStart();
if (GLGWTUtil.isEmpty(date)) {
return "";
}
return date.substring(4, 6) + "/" + date.substring(6, 8) + "/" +
date.substring(0, 4);
}
};
fosterDateStartColumn.setFieldUpdater(new FieldUpdater() {
@Override
public void update(final int index, final IFosterHistoryProxy
fosterHistory, final String value) {
final String[] dateParts = value.split("/");
if (dateParts.length != 3) {
return;
}
final int month = Integer.valueOf(dateParts[0]);
final int day = Integer.valueOf(dateParts[1]);
final int year = Integer.valueOf(dateParts[2]);
final String date = (year < 100 ? 2000 + year : year) + (month < 10
? "0" : "") + month +
(day < 10 ? "0" : "") + day;
getEditDTO(fosterHistory,
ECacheUpdateType.Update).setFosterDateStart(date);
final ViewData viewData = new ViewData(date.substring(4, 6) + "/" +
date.substring(6, 8) +
"/" + date.substring(0, 4));
fosterDateStartCell.setViewData(fosterHistory.getFosterHistoryId(),
viewData);
fosterHistoryGrid.redraw();
}
});
fosterDateStartColumn.setSortable(true);
fosterHistoryGrid.addColumn(fosterDateStartColumn, "Start Date");
fosterHistoryGrid.setColumnWidth(fosterDateStartColumn, "10ex");
The getValue() method is working well ... if the value in the proxy object
is "20120506" then I see "05/06/2012" in the cell. But the update() method
is not showing the correct value ... if the user enters "5/6/12" then I do
not see "05/06/2012" (the value in the cell is still "5/6/12" after the
update() method has executed). Note that the setFosterDateStart() method
does not cause the update to be sent to the server; it simply sets the
value in the editable proxy object. Also note that the
getFosterHistoryId() method returns the stable identifier value for the
IFosterHistoryProxy object, and that the key provider for the selection
model associated with the DataGrid is using that identifier.
Many thanks for any help!
Andy

DataGrid sorting and using setList in ListDataProvider
Hi, I just lost 2 hours on getting sorting to work correctly in my DataGrid backed by a ListDataProvider. I was calling setList( rows ) on the DataProvider to update the table and that works... but sorting was not working (I could not even see the sort indicator on the table header cells). Then it struct me: The ColumnSortEvent$ListHandler class takes a List as argument instead of the ListDataProvider. When you call setList() on the DataProvider a new wrapper is created and my ListHandler is looking at the wrong one. Wouldn't it be better that the ListHandler would keep a reference to the ListDataProvider instead ? Then it can call getList() on it when a sort is needed. It is now a bit asymetric: calling setList() updates the table rows, but the sorter does not know... I am sure many people fall in this trap!

Re: best way to attempt multiple times same RPC call
You could transparently handle this for all your requests of a given GWT-RPC interface by using a custom RpcRequestBuilder. This custom RpcRequestBuilder would make 3 request attempts and if all 3 fail, calls the onFailure() method. MyRemoteServiceAsync service = GWT.create(MyRemoteService.class); ((ServiceDefTarget) service).setRpcRequestBuilder(new RetryThreeTimesRequestBuilder()); The custom RequestBuilder could also fire a "NetworkFailureEvent" on the eventBus if multiple application components may be interested in that information. For example you could overlay the whole app with a dark screen and periodically try sending Ping requests to your server until network comes back online. There is also the onLine HTML 5 property you can check, but its not 100% reliable (https://developer.mozilla.org/en-US/docs/Web/API/window.navigator.onLine) -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

best way to attempt multiple times same RPC call
Hi, What is best way to attempt multiple time same RPC call? while RPC Call is getting failed. just example: In any case if RPC get fail due to network connection, it will catch in `onFailure(Throwable caught)`. Now here it should recall same rpc call again check network failure. The maximum attempt should be 3 times only then show message to user like "Network is not established" How can I achieve it? I can call same rpc call in onFailure but request become different. I want same request have a three request.

Chart and Graphs with Legend
Hi I am a newbie, i have some doubts in the gwt 1 - Here are the points which i need to customize the Line / Bar Chart a) Legend position Should come under the chart panel. b) Customized legend color change c) Customized font color, Size of legends d) Customezed Tooltip for graph 2 - For Separate Graph view In a single page user can see maximum four graphs at a time. But There is a selection criteria where a) If some select one check box a graph will come out full page. b) If some one select two checkboxes, two graphs will be displya in full page (one is left and another one is right ) c) If some one select three check box three graphs will come in the entire page (Two graphs Above and one below) d) if some one select four check box four graphs will come in the entire page (Above Two and Two Below) similarly i) If some one deselect a checkbox out of four selected three graphs will be display (Two graphs Above and one below) ii) If some one deselect another check box two graphs will be display in the entire page. can anyone guide me with simple example code will be a great help.

So, any thoughts on if this is worth pushing on with? A real generic need? I've missed an existing solution?
