Re: How to access a web page in Frame

[Slava Pankov]

Perhaps you have cross domain problem. Is URL in your iframe from the same 
domain as main application? If not you need something like proxy servlet to 
simulate you getting data from your server side.

The method isCompleteHtml(String) is undefined for the type SafeHtmlHostedModeUtils

[Adrian Bastholm]

Hi everyone,
I just upgraded GWT to 2.6 and I'm trying to use the SafeHtml utilities. 
Under debug the following message is thrown: 
Uncaught exception: java.lang.Error: Unresolved compilation problem: 
The method isCompleteHtml(String) is undefined for the type 
SafeHtmlHostedModeUtils

Eclipse Kepler doesn't find the SafeHtml classes on Open Resource, but the 
editor is finding them. What am I doing wrong ?

There must be other errors up in the log. There's a reason why deferred 
binding failed.

Re: The method isCompleteHtml(String) is undefined for the type SafeHtmlHostedModeUtils

[Thomas Broyer]

isCompleteHtml is public since 2.5.0. Make sure you don't have some 
pre-2.5.0 libraries (e.g. gwt-servlet.jar) in your classpath that could 
conflict with your updated GWT 2.6.0 libs.

I doubt option 2 is doable: sending any data (e.g. from the server to the 
client) would likely break decoding of the response on the client-side.

You have option 3 though: have your server spawn the processing in an 
asynchronous task and respond early to the client (if possible, you could 
also possibly wait for the task to complete, but no more than 50 seconds; 
if it's shorter then you'll send the task result right to the browser, 
otherwise you'll tell the browser that it's being processed 
asynchronously). The client then makes another request for the status of 
the task.
This is a major refactoring though…

Re: Cell Table Styling

Look at the Development Mode window (or the equivalent view in Eclipse if

(feel free to copy/paste the whole log if you need help understanding it)

GWT, ORM and jpa-cloner

[Mic L]

HI,
I have found a nice article "using gwt with hibernate 
example". 
However, GWT-RPC and Hibernate did not understand each other well.

Apparently, jpa-cloner  can solve 
this problem. Would it be possible to use the first version of the code 
describe in the above article together with JPA-cloner and Hibernate?

How the code would look like?

Thank you in advance.

Mic

Personally I would avoid using RPC and go with RequestFactory or Rest.

Using GWTTestCase to do integration testing on GWT-RPC calls

[stuckagain]

Hi,
 
I'm trying to create an integration test that checks if a GWT-RPC service 
is working with our integration test servers.
My initial thought was to just use a GWTTestCase and point the GWT-RPC 
ServiceDefTarget to the real server.
 
It did not work:

32 [JS executor for com.gargoylesoftware.htmlunit.WebClient@3afb2359] ERROR

I tried using a Filter that sets the Access-Control-Allow-Origin header to 
*, but it does not seem to work.
Is there a better way to perform this kind of integration test with GWT 
code ? Or is there a way to disable this check in HtmlUnit ?

Re: Responsive design with GWT

[Marteijn Nouwens]

Hi omar,

Yes it's possible. We do :-),  But we build a lot of our components our 
selves. The backward support for ie caused a lot of components to be ugly 
html wyse. SInce we dropped ie8 support a lot more is possible.

We like gwt because of the technology. The components are ok but we addded 
a lot :-)

MouseOver events flickering issue in Chrome & Mozilla

[Smiley]

 

Hi,

I am using a CellTree to display the data which I receive from the backend.

Items in a Cell

1.   Image

2.   Image

3.   Text

Requirement:

On mouseOver event on the Cell I need to show a button and on mouseout 
event I need to remove the button.

 When I move the mouse on the cell I could notice that multiple 
mouseover/mouseout events are getting fired and it creates a flickering 
effect in chrome and in Mozilla version above 18.0.

 I need some assistance in resolving this issue.

 

Thanks,

GWT Runtime Plugins - Is it on the Roadmap?

[Thanos]

I was wondering if GWT Runtime Plugins are on the roadmap yet?

We have GWT compile time plugins working quite nicely, each plugin is a 
maven module. After the number of plugins gets large, this really starts to 
bog down the compiler. So it would be great if plugins where pre-compiled 
and "linked" at runtime in the browser. 

I know this sacrifices .js size, as it can't prune as aggressively. But for 
our type of application, an extensible workbench, it would really help; and 
would probably be an acceptable tradeoff. Both to improve development 
speed, but also as we have a requirement to allow 3rd party plugins to be 
added at runtime.

For those interested in our extensible Workbench work, you can see a number 
of videos here:
http://blog.athico.com/2013/12/drools-60-workbench-and-editor-videos.html

I know there are hacks, such as loading lots of GWT applications on a 
single page, and bridging them. But i'd like to avoid any painful hacks. I 
was hoping that the new closure compiler, with it's support of symbol 
tables, might make this possible?

Our main choice for choosing GWT is re-factorable development in an IDE, 
and less so about absolute minimum .js size (although of course we don't 
want too much bloat).

Mark

Re: How to access a web page in Frame

[Leon]

I used a proxy servlet so the url for Frame is the same origin (same 
scheme, host, and port) as widget. But Document.getElementsByTagName("div") 
still returns an empty NodeList.

Please help!

 If you need that more often then you should probably extend GWTs Frame 
 class and make a public method to access the content document.

 Keep in mind that you should wait until the frame is loaded using 
 frame.addLoadHandler().
