Re: Design Decision RPC with AsyncDataProvider

[Jochen Schnaidt]

Hi,

I now started to give my columns DataStoreNames, works much better for a 
couple of requirements.

Thank you so much for helping me on this topic.

Best regards

If you can make a small repro case, please file an issue; it looks like a 
critical regression (which would also mean our test suite is weak)

You definitely *can* change the log level from the command line, WARN is 
just the default value.
Arguments are passed to JUnitShell through the gwt.args system property, 
the same you use to set your custom RunStyle: -Dgwt.args="-logLevel DEBUG 
-out www-test -runStyle com.example.PhantomJS:/path/to/phantomjs"

Yes, we need to document them (or update existing documentation) and 
possibly deprecate a few of them.
When xsiframe was introduced a few releases ago, it was said that it could 
eventually replace std as the default linker: it combines the best of 
iframe (sandboxing in an iframe, DevMode) and xs (cross-origin), and is 
modular and extensible (you can even "plug" your own script "fragments" 
using ), and of course also brings 
SuperDevMode. I think "xs" should be deprecated, maybe sso too (who 
compiles a single permutation anyway?)
AFAICT, Google's  linker (Server-Side Selection Script) is based on 
xsiframe (or direct_install, which extends xsiframe)

No, the gwt-maven-plugin is doing something wrong: it does not allow you to 
configure the logLevel:

Dynamic place navigation

[Prince]

Hi,

I have a requirement to navigate to the places where place is dynamically 
decided.

For example,

I have an "Edit User" link from Screen-1 & Screen-2. When I click on the 
link, it takes me to EditUserView.java. Now, when I click on Save button 
from my EditUserView.java, it should take me to Screen-1 if I come 
from Screen-1 and to Screen-2 if I come from Screen-2.

Is there any way I can achieve this?

Thanks

Re: Dynamic place navigation

[Jens]

History.back(); maybe? 

If this doesn't work for you then store the previous place in the current 
place so you can call 
placeController.goTo(editUserPlace.getPreviousPlace()); later on.

Add the "return-to place" to the "edit user" place (that doesn't mean you 
surface it in the URL through the PlaceTokenizer though), so you can use in 
from your EditUserView (and choose a sane default when the place is 
constructed from the URL and doesn't have a "return-to place"; as an 
alternative, just put the "return-to place" in the URL, serializing it 
using the PlaceHistoryMapper).
As an alternative, you can use 2 distinct places *resolving* to the same 
EditUserView.
In any case, the idea is to choose the next place based on the current 
place.

JUnitShell.getModuleUrl() produces invalid URL for IPv6 addresses

[Maik Riechert]

Hi,

it seems the JUnitShell is generating invalid URLs if IPv6 is used:

http://2607:f700:8000:12d:dd58:687b:744c:800c:48579/...

You can observe this here:
https://travis-ci.org/neothemachine/KineticGWT/builds/8191369#L881

The URL should be 
http://[2607:f700:8000:12d:dd58:687b:744c:800c]:48579/...

Is this a known issue? I couldn't find anything related to that.


Cheers
Maik

I don't think I've seen a bug report about that. This is due to 
constructing the URL by string concatenations; using java.net.URL or 
java.net.URI, the brackets could be added automatically if needed 
(depending on the constructor used).
As a workaround, because you're working on a custom RunStyle, override 
RunStyle#getLocalHostName to add the brackets when the InetAddress is an 
Inet6Address.
Feel free to file a bug in the issue tracker. And it'd be awesome if you 
could provide a patch! (note that there's a similar issue in 
RunStyleSelenium I guess)

Re: Application architecture question

[Imy]

Follow up on this matter.

Thanks you for all the inputs, we considered them and decided what is the
best solution for our project.

In the end we created an object that models the data that we receive from
the database and from the after calculations.
In the HomeActivity class of the HomeView (in case of mGWT) or Presenter
class (case of GWT) we create an onModelLoaded event handler which fills
the model. We also implemented states and the readyState is only activated
when the model is loaded. From the model we also fill the GUI afterwards.

Cheers,
Timea

Beginning...Problems with navigation

[Carmen]

Hi, 

i'm just beginning with GWT  and I have a problem to make my application 
behave as I want. The fact is that I have one main static html page that 
links to three "subpages" that are similar but contain a dynamic part each 
one. Must I use one single entry point to the main page? If I choose this 
option...how can I continue navigation (as events, perhaps)? I also thought 
of creating three modules for each "subpage", each one with its XML file 
that make me able to control the dynammic part, but I really think this is 
not useful

Has anyone an idea of how to manage this?
Thanks a lot

Re: Beginning...Problems with navigation

[Joseph Lust]

Carmen,

Can you elaborate on what you're trying to build and what it does? GWT is 
intended for Web *Apps*, not Web *Sites*. So, typically GWT would not be 
used for a blog, but it would be used for say an employee time tracking 
application. Take this forum reader as a good example of GWT.

The strength of GWT is that you are only on a single (physical) web page. 
All user interactions update the page content and the browser history, but 
the user does not need to make a trip to your server to reload the page, 
making everything faster and lower overhead.

Of course it is a different ball game from PHP or JSP's, but I'd posit it 
is more straight forward with less boilerplate than those implementations. 
Check out frameworks like GWTP which handle those events and pages you just 
mentioned rather seemlessly. They've got a number of ready to code demos 
too.


Sincerely,
Joseph

This is likely a bug in gwt-test-utils. Does your app compile? Does the

the ScrollEvent is never fired, I put a breakpoint on onScroll and it never 
breaks!
Here is the code:

public class InfiniteScrollPanel implements ScrollHandler {
String text = "Lorem ipsum dolor sit amet, consectetuer...";
ScrollPanel panel;
String height = "1200px";
String width = "200px";

public InfiniteScrollPanel() {
panel = new ScrollPanel(new HTML(text));
panel.setSize(width, height);
panel.addScrollHandler(this);
panel.getElement().getStyle().setBackgroundColor("rgb(216, 216, 216)");
}

@Override
public void onScroll(ScrollEvent event) {
if (panel.getVerticalScrollPosition() == 1100) {
panel.add(new HTML(text));
}
}
}

Then I add it like this:

InfiniteScrollPanel demo = new InfiniteScrollPanel();
RootPanel.get().add(demo.panel);

Any ideas?

Re: How come the ScrollEvent is never fired in this code?

Your ScrollPanel never needs to scroll if it really has a height of 1200px 
but only contains such a short text.

Also ScrollPanel extends SimplePanel so it can only have exactly one child 
widget. That means if onScroll() executes you will see an exception because 
you are trying to add a second child to ScrollPanel. What you want is: 

ScrollPanel (height 1200px)
---> FlowPanel
  -> child 1 (should be taller than 1200px so ScrollPanel can 
actually scroll it)
  -> child 2

Re: How come the ScrollEvent is never fired in this code?

[Mohammad Al Quraian]

Ok I got it, Thank you very much Jens. One question though, I wanted to 
make an infinite loop panel, is this the way to do it, how can I do without 
having the scroll bars, I know I can hide them in CSS but this would stop 
the scrolling event from firing. You don't have to answer me in detail I 
just need a general idea if you have the time.

Cheers and thanks again.

Gwt Time picker widget

[Kedar Vyawahare]

Hi,
I am looking for a widget in GWT that allows the user to choose a specific
time. I am using the GWT Date Picker to choose the date but I am not able
to find a suitable Time Picker. I have had a look at a couple of
suggestions  that emulate the jQuery Time Picker as well as GWT Incubator
Demo but none match my requirement. I am looking for a space-efficient
widget maybe like a textbox that allows to enter suitable time values.
Thanks in advance
