Editors Framework

[saurabh saurabh]

Hi all,

I have a situation here

@Entity
@Table(name = "person", catalog = "hms")
public class Person implements java.io.Serializable {

private int id;
private Integer version;
private Address addressByAddress1;
private Address addressByAddress2;
private String firstName;
private String middleName;
private String lastName;
private String sex;

  /*other fields and methods*/

}
public class PersonEditor extends Composite implements
Editor {

@UiField
ValueBoxEditorDecorator name; //note: doesn't follow editor
contract of naming convention.

/*other uifields following editor contract*/

}

So I am using just one text box for firstNam, middleName, lastName :
the name box.
I am trying to make a smart name input field for user where user can
just enter the name with spaces and the value in testbox using some
split function and logic will be absorbed by firstName,middleName,
lastName.

So here just for three fields I don't want to implement the
LeafValueEditor. I was thinking there must be some thing where I can
subscribe bean's initialization get and set method and implement this.

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

[Zak Linder]

Sorry, you need to added !important because the styles you're overriding 
are defined inline:

/* hack to remove sort icon */
.
cellTableSortedHeaderAscending > div,
.cellTableSortedHeaderDescending > div {
   padding-left: 0* !important*;
}
.cellTableSortedHeaderAscending > div > div:first-child,
.cellTableSortedHeaderDescending > div > div:first-child {
   display: none* !important*;
}

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

[Zak Linder]

I don't think this will work, the arrow icon is added by wrapping the 
header Cell in an 
IconCellDecorator(in
 AbstractCellTable.getSortDecorator(), which is called in 
AbstractCellTable.createHeaders(), both private methods).

I have a similar issue in that I want to move the icon to the right of the 
label, so I also need to target the icon. Xavier, you could try using CSS 
to hide the icon. Just as you've replaced the icon resources in you 
TableResources interface, you can replace and extend the CSS file:


public interface TableResources extends CellTable.Resources {
@Source("up.png")
ImageResource cellTableSortAscending();

@Source("down.png")
ImageResource cellTableSortDescending();

@Source("MyCellTable.css")
CellTable.Style cellTableStyle();
 }

And in MyCellTable.css:

...

/* hack to remove sort icon */
.cellTableSortedHeaderAscending > div,
.cellTableSortedHeaderDescending > div {
   padding-left: 0;
}
.cellTableSortedHeaderAscending > div > div:first-child,
.cellTableSortedHeaderDescending > div > div:first-child {
   display: none;
}

...

The CSS above undoes the cell decorator's padding and hides the icon. If 
you need help with getting the CSS to work the first place to look is the 
ClientBundle 
dev 
guide
.

 Yes I am aware of this. There have been further developments recently

I'm hitting App Engine's application static file limit of some 150MB

[Brandon Donnelson]

I'm hitting App Engine's application static file limit of some 150MB. 

Seems that when I try to deploy a second mirrored GWT module adds some 
overhead that throws me over the limit. This second module I have a 
slightly different configuration going on for local stuff, which I can 
remove to get it deployed but the request factory symbol files and 
additional project files overhead adds to my deployment size. 

While I've encountered this before and I have moved to serving files to 
blob datastore but it would be harder manage and serve my static project 
files I think. And I'd like to add more Google Api libs in the near future 
as I add more features to my application, but now I worry about my 
deployment sizes. 

I'd like to suggest a slightly larger static files deployment container for 
hosting app engine apps. Until then I'll be prudent in what I add to my war 
directory :).

Re: RF: error.getExceptionType() returns null in Receiver#onFailure

[Jens]

Because the DefaultExceptionHandler in RequestFactoryServlet hides server 
details and only gives you the exception message. 
See: 
http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/web/bindery/requestfactory/server/DefaultExceptionHandler.java

You have to sub class RequestFactoryServlet and provide your own 
ExceptionHandler if you want to change that behavior.

Weird. have you tried throwing another type of exception?

Re: Inserting a DIV in a GWT Panel

if you can wait until tomorrow, i can take a look at a method that cuts

I'm not sure, but try to remove the style "display:none" or change it
(something like footer.setProperty("display", "xxx")) when you append

Inserting a DIV in a GWT Panel

[Xybrek]

I have this DIV on my application jsp page which I need to "inject" in 
to a GWT VerticalPanel. Coded on top of the iframe tag which contains 
"__gwt_historyFrame" :


**index.jsp**

I am inserting the DIV to the view with this code:

DivElement footer = (DivElement) document.getElementById("footer");
verticalPanel.getElement().appendChild(footer);

However it does not show up, although the `getElementById` does not 
return `null`


What is the correct way to do this?

Re: Anyone using gwt-rpc over websockets?

[Yaya @ Work]

Hi !

Don't forget that websockets will only be used if both the server and the
client support them.

Also, your goals are a bit unclear :  you mention RPC, which is client
initiated communication, and websockets, whose initial aim was to push data
from the server to the client.  However, indeed, both types of
communications could (should ?) be unified, see below.

Regarding Atmosphere, I played a very little bit with this framework a few
few months ago, for a PoC I left aside, and wasn't very excited :  the
documentation was quite shallow and the framework itself is quite "low
level".  Basically, it allows you to send strings from the server to the
client, with some support for object serialization which is/was a bit
tedious.  I don't remember any support for client initiated communications.
 However, this opinion should not be taken in a too harsh way :  Atmosphere
is a generic framework, with a bit of specialized support for GWT, not a
GWT specific framework.
Also, at Devoxx FR 2~3 weeks ago, Sami Jabber reported a similar
"disappointment" with Atmosphere (
http://www.slideshare.net/samijaber/session-gwt-devoxx-france-2012-cobra,
slide 11, sorry that's in French ;-) ), although they may have evaluated
this while ago, on less mature versions.

Anyway, I'd rather recommend you to have a look at JBoss' Errai [
http://www.jboss.org/errai.html], which adds very nice stuff on top of GWT,
like CDI, JAX-RS related stuff and "a unified federation and RPC
infrastructure with true, uniform, asynchronous messaging across the client
and server".
Regarding communications, see e.g.
https://docs.jboss.org/author/display/ERRAI/Messaging :
This section covers the core messaging concepts of the ErraiBus messaging
framework.
ErraiBus forms the backbone of the Errai framework's approach to
application design. Most importantly, it provides a straight-forward
approach to a complex problem space. Providing common APIs across the
client and server, developers will have no trouble working with complex
messaging scenarios from building instant messaging clients, stock tickers,
to monitoring instruments. There's no more messing with RPC APIs, or
unweildy AJAX or COMET frameworks. We've built it all in to one, consice
messaging framework. It's single-paradigm, and it's fun to work with.

Best regards,
  Yannis
