Re: [gwt-contrib] SNAPSHOT of 21 Sept breaks my build (invalid namespace

['Roberto Lublinerman' via GWT Contributors]

The error suggests a class path issue. The same patch that introduced
 in native string relaxed the checking for namespaces in the
compiler to allow this situation (
https://gwt-review.googlesource.com/#/c/16881/).

Re: Update conversation by displaying new messages when they are sent

Others have suggested websockets, but there are several other options as 
well.  There is google cloud messaging and many other libraries to solve 
this problem as well as ServerSent Events.

http://www.html5rocks.com/en/tutorials/eventsource/basics/

If none of those are options, try to avoid using a regular timer.  More 
timers, more problems.  If you must use a timer like object, I would 
suggest using gwt Scheduler instead.

Re: Setting Width of a TextBox inside LayoutPanel

[Chris Odd]

My original issue was that for textboxes, the call to

pnl.setWidgetLeftWidth(tb, 0, Unit.PCT, 100, Unit.Pct);

does not work.   Other widgets are fine, but for some reason textbox is 
different.


.LabelledTextBox {
-webkit-box-sizing: border-box; 
-moz-box-sizing: border-box;   
box-sizing: border-box;
width:100%;
height:100%; 
}

The issue is not that the panels are incorrectly sized, but that the TextBox 
inside the panel does not expand to take up 100% of its container width, even 
though I call

pnl.setWidgetLeftWidth(tb, 0, Unit.PCT, 100, Unit.Pct);


Other non-textbox widgets seem to behave just fine.   Not sure what is 
different about TextBox. 

I did get it to behave the way I wanted using the following workaround… not 
fully programmatic, had to use CSS:

tb.setStylePrimaryName("LabelledTextBox");

and then putting this in the CSS:

.LabelledTextBox {
-webkit-box-sizing: border-box; 
-moz-box-sizing: border-box;   
box-sizing: border-box;
width:100%;
height:100%; 
}

Re: [gwt-contrib] Re: SNAPSHOT of 21 Sept breaks my build (invalid namespace

[David]

I'm using maven and I only have a dependency on 2.8.0-SNAPSHOT.
I have forced an update of the snapshots in an eclipse refresh and now it
seems to work.
I guess it was a local maven/nexus issue ?

I hope -strict becomes the default, why would you want to ignore errors ?
In most cases it is hiding some issue that will surface later.

This actually is not possible, and a limitation of GWT itself (JUnitShell

Re: AutoBeanCodexEncode does not encode numbers when zero is the value

[Yann Vo]

For what it's worth, more than 3 years later... one workaround to have zero 
values serialized (along with the key) as you ask for is to use an Integer 
rather than an int.
This is the JavaScript semantic (anything can be undefined or null) and 
then it behaves as other JSON serializers to omit null value but not zero 
values.

Hope this helps if anybody ever reads this...

Extending native JsTypes from Java with GWT 2.8.0-rc2

[Nándor Előd Fekete]

Hi everyone!

Are we supposed to be able to extend native (browser) JsTypes from Java? 
Specifically, having the following declaration (from Elemental2):

@JsType(isNative = true, namespace = JsPackage.GLOBAL)
public class HTMLDivElement extends HTMLElement {...}

and the extending type

public class DummyElement extends HTMLDivElement {...}

I'm getting TypeError: Illegal invocation from the compiled js code when it 
tries to define the class (com.google.gwt.lang.Runtime.copyObjectProperties 
(Runtime.java:104)), while copying native properties from the extends js 
type's prototype. The property in this case is 'align' but it happens on 
other browser native properties too.

Thanks for the help!

All the best,
Nandi.
