what date libraries are you using?
Like many I'm a fan of Joda-Time. I'm curious what date libraries are popular, if any, for GWT client side. Goda looks dead. GWT-Time looks as it might be of use. Maybe pure javascript date packages are the way to go? Whats been successful in your projects? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: ImageResource question
Beware when implementing com.google.gwt.resources interfaces (whose
implementations are expected to be generated) that they might change and
break your code. GWT 2.6 will introduce a new isStandalone() method for
instance.
Also, BTW, you should probably use UriUtils.unsafeCastFromUntrustedString;
it works exactly the same as fromSafeConstants, it's just a matter of
"semantics": one says it's "safe" when the other clearly states that it's
"unsafe but necessary".

Re: what date libraries are you using?
Each day I pray that Java 8 won't get delayed any further and that GWT will include JSR 310 once Java 8 is released. Currently I just avoid date manipulation code in shared classes. On client I use the Date class with its deprecated methods behind a date manipulation utility class and on the server I use JodaTime. So nothing fancy. Luckily I don't have to deal with timezones yet. Only issues I had so far are daylight saving time issues for some dates. Looks like Linux, GWT and web browsers all have slightly different information about DST.

gwt-google-apis library
This question should be posted on the gwt-google-apis forum but I am not sure if anyone actually checks it (last post is from last year). I have been using the gwt-google-apis library (specifically gwt-visualisations) extensively. However there hasn't been any update to the library for a long time. In the meantime most of the JS libraries (gwt-charts, etc) have been evolving but the gwt wrappers haven't been updated to support new features. So I ended up copying the src and modifying it myself, but that's probably not the ideal solution (there are also a couple of other open source repository on github/google-code). Are there any plans by the SC members for handling this situation? I could imagine it should be possible to move it over to github and open it contributions by the community. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Build a DataGrid with 2 proxies
Hi guys, Is it possible to mix up datas coming from multiples proxies on to a DataGrid or do i have to create a new proxy containing both ? table = new DataGrid(numRows, GWT. create(TableResources.class)); initWidget(GWT. create(Binder.class).createAndBindUi(this)); Column nameColumn = new NameColumn(); table.addColumn(nameColumn, "Acolumn"); table.setColumnWidth(nameColumn, "25ex"); table.setColumnWidth(descriptionColumn, "40ex"); table.addColumn(new CpColumn(), "BColumn"); Would like to add a column like Column ficheColumn = new FicheColumn(); table.addColumn(ficheColumn, "Demandeur"); It says The method addColumn(Column, String) in the type AbstractCellTable is not applicable for the arguments (Column, String) Regards, pierre -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Build a DataGrid with 2 proxies
BProxy would need to extend AProxy. If you don't want that you have to use a third class/proxy that contains AProxy and BProxy. In both cases your columns must then figure out what data to render (using instanceof or null checks depending on your solution). -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

get scroll event from iframe
there seems to be no way in GWT to get the iframe scrollEvent.
I tried
(com.google.gwt.dom.client.IFrameElement)frame.addDomHandler(newScrollHandler()
{
@Override
public void onScroll(ScrollEvent event) {
// do something
}
}, ScrollEvent.getType());
but the event does not fire when scrolling
inside the iframe, you can get
Document document = iframe.getContentDocument();
but it does not have methods for adding listeners. there is no method for
returning the contentWindow like in javascript.
any one knows any way to get the iframe scroll event?

Access POST parameters via servlet?
I'm creating a GWT application that, when accessed, will be passed POST
parameters (user id, etc.).
All the reading I've done so far has led me to believe that I should create
a servlet (I'm using tomcat) that will handle the POST parameters and then
forward to my GWT application. I've gotten this working, but I'm still
having trouble passing this data to my application. I've seen 3 suggested
approaches:
1. Save data to context: I have this working right now, but I'm not
happy with it. When the servlet is accessed, I parse the parameters and
update the context of my GWT web application and then forward to the
application where I make an RPC call to read the context. This does what I
want it to, but this creates a race condition when multiple users try to
access the application at the same and the context is rapidly changing.
2. Store data in session: I've tried saving the data to the request
session in my servlet, and then doing a
"response.sendRedirect(response.encodeRedirectURL("url"))" but I've not
been able to access the same session. When I do
"this.getThreadLocalRequest().getSession()" I always get a new/different
session, so I assume I'm mucking this up somewhere.
3. Pass data in URL: My application will be opened in an iframe,
meaning "Window.location.getParameter()" will not be usable.
Any help would be greatly appreciated! I'm still learning GWT and web
development in general so don't be afraid to call me out on any obvious or
silly mistakes.
Thanks!

Your GWT application runs on the client side. Are you saying the host page is sent to the browser in response to an HTTP POST request? If so, the typical way to propagate extra information to the client app is to embed them in the host page (e.g., a hidden with some data, or a
Problem with AbstractCell in IE
Hey,
i've got a problem with an AbstractCell.
I created a class to get an image link. This class extends an abstract cell.
To display the link I created a SelfHTML template. This looks like this:
@Template ( ""
+
"" +
" " +
"" +
"{1}")
SafeHtml hyperImageText( SafeUri link, String text, SafeUri image,
String target );
In every Browser it's working fine but in InternetExplorer you can only
click on the Image an not on the text. Thats a little bit anoing to our
cutomers.
The rendred output from InternetExplorer is:
http://heise.de"; target=_blank>
heise.de
Any idea how to fix this ?
Thanks in advance ;)
