Re: Is there any way to remove the sort arrow decorator in a header of a CellTable?

[Olivier TURPIN]

Hello Xavier

You should take a look at Header class (in 
com.google.gwt.user.cellview.client package) by extending it you'll have 
access to the Template in use, maybe you can declare your own or just 
override render method  and inject your code to the SafeHtmlBuilder

@Override
public void render(Context context, SafeHtmlBuilder sb) {
// do what you want with the builder
// sb.append();
}

Re: GWT-RPC Portlets Liferay

[Olivier TURPIN]

Hello,

There is some resources about GWT-APP management on liferay's forum :
http://www.liferay.com/web/guest/community/forums/-/message_boards/message/461945

http://www.liferay.com/web/guest/community/wiki/-/wiki/Main/How+to+build+a+GWT+Portlet+in+Liferay

I think that there is a gwt sample with the demo bundle, did you try
it ?

Maybe you've got some troubles with contextpath (N.B i'm not a Liferay
expert...°)

Re: vertical alignment inside a FlowPanel

[Olivier TURPIN]

Hi magnus

vertical-align works only on inline elements, FlowPanel / SimplePanel
(div elements) are 'block' types, i don't know exactly what you're
trying to achieve but bottom alignment can be painful sometimes...

if you don't care about IE6/7 you can have a try with :

#mainContainer{
vertical-align:bottom;
display:table-cell;
}

Re: Is there a alternative way of debugging under Linux

[Olivier TURPIN]

I'm running my projects under Ubuntu 64-bit (with FF plugin as the
plugin for Chrome is not available)

as mentioned by Thomas, when needed, i start a VM on Windows to
complete tests with IE (for this purpose the -bindAddress parameter
could be interesting so as to override default 127.0.0.1 address)

Re: GWT encoding problem

[Olivier TURPIN]

Hilco gave the right answer, that's a maven log

you've got to tell Maven to use UTF-8 during processing (otherwise it
will fallback to system encoding : ) :


  ...
  
UTF-8
  
  ...

Re: Speed-Optimization of an application (RPCs, Architecture)

[Olivier TURPIN]

in a near future if you need to play with command pattern you could
find some interesting hints with thoses articles :
- Tutorial explaining the basics of gwt-dispatch :
http://borglin.net/gwt-project/?page_id=283
- Nice articles about batching with gwt-dispatch (by the M. David
Chandler)
http://turbomanage.wordpress.com/2010/07/16/dispatchqueue/
http://turbomanage.wordpress.com/2010/07/12/caching-batching-dispatcher-for-gwt-dispatch/

PS it's always good to keep in mind browser's limitation but the
limitation of '2 connection /server' tend to move to more ajaxfriendly
values with the newest version of FF, IE ...

Browser HTTP/1.1HTTP/1.0
IE 6,7  2   4
IE 86   6
Firefox 2   2   8
Firefox 3   6   6
Safari 3,4  4   4
Chrome 1,2  6   ?
Chrome 34   4
Opera 9.63,10.00alpha   4   4

Re: What are some of the most valuable frameworks in your project?

[Olivier TURPIN]

Well i tried mvp4g in late 2009, GWTP and GUIT were not available...
only gwt-presenter.
So i made proof of concept with both frameworks and i really like the
way mvp4g did. Simple configuration, annotation facilities for
binding, splitability, nice support... and i like the fact that there
is no 1 million concepts and features that i won't use (as I prefer
'raw' GWT than getting into swartGwt and GXT for same reasons)

Re: accents problem

[Olivier Turpin]

Hello Laurent,

Did you check :
- eclipse workspace settings (UTF-8 vs ISO)?
- JVM file encoding ?
- Apache (if used) default caracter encoding ?

what's the response/request header encoding ?

Is your trouble only on your csv file ?
