How to unit test GWT serialization?

I'd like to write a unit test to test GWT serialization, any pointers
on how to setup a unit test that would allow me to pass a variety of
data structures from the client to the server and compare results? Is
this even possible?

GWT Serialization error with HTML String content

Using GWT 2.4. I'm trying to track down the root cause of this...not
sure if I'm doing something wrong or this is a bug someplace.

This happens when I send the following HTML as a string to the
Atmosphere comet framework but that framework just seems to pass this
to GWT's ClientSerializationStreamWriter &
ServerSerializationStreamReader. Here is the string that fails:
<div style="font-family: Arial; font-size: 10pt;"><div
class="chatline" style="text-indent:-10px; margin-left:10px;"><span
class="timestamp-self" style="color:#FF0000;">(Apr 30 2012 15:11:33) </
span><span class="from-self" style="color:#FF0000;">tom: </span><span
class="message">a</span></div>
</div>

But this string works fine with same method:
<div style="font-family: Arial; font-size: 10pt;"></div>

What's going on here? Is there some known restrictions sending HTML
with GWT serialization? How to fix this?

Re: RequestFactory and Value Proxy for Objectify Key problem

For anyone else that passes this way looking for the cause of the AssertionError: Incorrect size: 2 in AutoBeanCodexImpl$CoderCreator.getCoder()...

I had an AutoBean with an ArrayList<AnotherAutoBean>.  I changed it to be just List<AnotherAutoBean> and it fixed the problem.

when looking at it in the deubugger, there appear to be 2 coders.  The

mgwt pays a lot of attention to do things in a GWT way, which brings

Re: GWT Mobile App Widgets

Yes, if you are trying to cover that case, then you must absolutely
find a mobile library that can potentially support any of the
installable browsers in mobile devices. The important case to always
keep in mind I would say is over engineering. Unless it's a
requirement from the client, I would ask myself the question, what
percentage of the market am I trying to support? Ideally the answer
would be 100%, reality it's a different story. This is more the case
since mobile web is fairly young. Even the web after all these years
would be a nightmare if you removed GWT and libraries like it that
have tried to make the developer experience better by hiding the
browser differences or better said quirks.

About a year and a half ago, perhaps more already, there was a point
where the future of mobile web for developers looked bright. It was
all going to be based on webkit or at least most of it and the world
was going to be a happy place.

Fast forward and we find a world where there is an incredible amount
of fragmentation in the mobile market place with multiple versions of
webkit, many don't exactly behaving consistently. Throw into the mix
your request and it's almost starting to feel like we are right back
to the web as we know it today where may browsers exists with
difference in behavior not only between them but even among versions.

Best of luck and wish your project the best.

Re: GWT Mobile App Widgets

I did a little research a while back. Here are my notes;


m-gwt
http://code.google.com/p/mgwt/
Set of mobile widgets and transitions for GWT. The widgets are quite
good and work on desktop, tablet and phones. My Android 3.1 tablet
has trouble with the history, but that is a small problem. The
library is well integrated with standard GWT. It uses CSS3
transitions and animations for efficiency. It uses separate CSS files
for each browser profile, so it is easy to use the correct sizes and
transitions based on browser type. Integrates with gwt-phonegap to
create installable applications. The associated blog is also very
informative.

There is a demo site to show how mGWT performs in mobile and desktop
browsers. It is a single site that uses different CSS to display
itself for these different form factors. mGWT performs more smoothly
than GWT Mobile, but it does not have as many widgets and features.
It works well on an Android phone, Android tablet (that is
impressive) and desktop webkit browsers. It does not work at all on
IE9 (so, more work would need to be done to create a browser profile
for IE). The history management works well in both the desktop and
mobile browsers, which is a big advantage over GWT Mobile.

GWT Designer was recently updated to support mGWT, so it is well
integrated with Google's tooling.

GWTMobile
http://code.google.com/p/gwtmobile/
GWTMobile is a framework that includes mobile UI widgets, a
persistence api and a phone-gap wrapper. The Android store has two
demo apps that can be installed.

The apps run using GWT-PhoneGap and perform pretty well on an Android
phone. I would say most of the transitions are not that good. The
mGWT transitions work much better.

There is a separate browser demo for desktop and mobile. In both
cases, the views are formatted for a phone (the desktop site runs in a
picture of a phone). The mobile demo works well on an Android phone
and feels almost identical to the demo app, except the history
management is broken. I keep hitting the back button and leaves the
demo site, which is very aggravating. Again, the transitions are
better on mGWT, but GWT Mobile has more user interface widgets.

The demo site does not run on IE.

CAVEAT: I have not used either of these libraries. I looked at their
demos on desktop and mobile browsers. I also downloaded the mobile
apps (both based on PhoneGap).

Re: GWT Mobile App Widgets

Well the app runs fine on iPhone Safari, Google Chrome, and the
Android Default Browser.
However the app does not work on Firefox and Opera installations on
the Android platform, so that could be a problem.
So still hope someone can make a suggestion.

Editors and automatic object updates/change propagation.

It appears that the GWT Editor framework only supports explicitly pushing updates to the object being edited by calling the driver's flush() method. However, I want to validate properties as they are changed. Thus in the case of a data-bound form, I'd like to validate a property as soon as the corresponding form field loses focus. I'm using JSR 303 validation to validate the bean being edited, so the state of the bean itself needs to be updated.

Is it possible to automatically propagate Editor changes to the object being edited rather than explicitly invoking flush()?

Re: Installing gwt on RAD 7.5

Hi,

Many Thanks for your reply, 
but i dont have  Available Software Sites  option under the  windows>Preferences>Install/Update

did you exprienced this problem?


2012/4/30 Adolfo Panizo Touzon <adolfo.panizo@gmail.com>
Yes, it's possible. I had problems too.

I've solved by going to "windows>Preferences>Install/Update>Available Software Sites" and clicking in Eclipse Helios 3.6 and Helios Milestone Repository.

The exactly path that you have to use is: http://dl.google.com/eclipse/plugin/3.6

PD. The rest of my team had to add more software sites, so..., play and try. 

Regards,

Adolfo.

Re: Firefox 12 release

Roger:

I agree with the opinion that excessive FireFox releases are hard to keep up with. Our FireFox constraint is due to customer demand. All of our large telecommunication customers standardize on FireFox through out their company for it's stability (the majority also run Windows clients).

Re: Parser xml on server

Hi all, I have a similar problem.

If I wanted to share a class that has a method 'loadXmlString(String xml)'  and I wanted to use it sometims client side, sometimwes server side, how could I do? I see that client side this works using com.google.gwt.xml.client.* classes, but when I try to execute it server side, a "java.lang.NoClassDefFoundError: Could not initialize class com.google.gwt.xml.client.XMLParser"  error occurs. How can I solve this problem? Do I have to implement the same parsing algorithm twice? One client side and one server side? I can't believe that!

Please help.

The Dart project is also not based in ATL and most definitely is not being cut in any way, shape or form.

Re: GWT Mobile App Widgets

Mobile web libraries are based on webkit. Firefox is not. Mobile devices use webkit. To test the app you can try to use a webkit based browser such as chrome or safari. So if you are happy with that library I recommend you continue using it and test it as previously mentioned.

Re: Google axing GWT?

GWT is not based in ATL and we are definitely not axing it. GWT has been based in Mountain View for most of the past year and that is where all of the GWT 2.5 work that Ray Cromwell references is being done. GWT 2.5 has taken a bit longer to get out than we originally planned, but it also includes some very significant new functionality (like Elemental which Ray references in his G+ post). The GWT project remains very stable and viable, and we plan to keep it that way long term (keep in mind that Google relies on GWT just as much as the external community). Any changes planned for the GWT team will actually help ensure that and are unrelated to anything going on in ATL.

Re: How to find that an element is now in view on the screen

There is no built in browser mechanism to achieve this, however you can look at the offsets of the target element and its containing element and deduce it yourself.


Also, note that the getClientRects() DOM method can also give you the bounding box information. Still, you'll need to do the math yourself to see if the element is visible or not.


If you want to have something always visible however, why have it in a scroll panel? Why not just place in an absolute position so that it does not scroll?


Sincerely,
Joseph
