Re: Strippable check system in GWT 2.8?

Thanks for the explanation Thomas. I think it should be safe to disable 
them then in my case. :-)

Re: Handling Violations controlled by groups or Violations not found by default validation

[Alex opn]

Thanks for your answer!

Well...propably I'm abusing bean validation (?), but in my case that 
doesn't help (actually I'm already doing it like this with different 
groups).

I'll try to explain my problem:

Basically I've got two validation groups which both should be run on the 
server-side: Client and Server 

Client: These validators should be run when an object enters the server 
from the client (in the ServiceLayerDecorator)
Server: These validators should be run before persist / update etc happens 
(in my DAOs)

The reason why I separated it like this is that there are some class level 
constraints which may be violated when an object enters the server that 
should get corrected in the service method afterwards, but for safety be 
checked again before updating the database.

So far that works good and was pretty easy to implement:

ServiceLayerDecorator:

@Override
public  Set> validate(T domainObject) {
return validator.validate(domainObject, Client.class);
}

But ViolationExceptions occuring later are, as Michael already explained 
pretty well, reported as ServerFailures, not as ConstraintViolations -> 
non-resusable RequestContext, no error messages shown etc :-/

I already tried to copy/paste SimpleRequestProcessor & 
RequestFactoryServlet (into com.google... package structure) to change it 
to my needs. I have to admit though that I couldn't figure out how to catch 
all exceptions and not handle ConstraintViolationExceptions as server 
failures. I would already be happy with that although it feels a bit hacky 
:)!

Re: CellTable - how to change icon positon?

[Alex opn]

Have a look at the 
CwCustomDataGridfrom
 the showcase. You'll have to create a custom header builder 
extendingAbstractHeaderOrFooterBuilder. 
AbstractHeaderOrFooterBuilder offers a method "

setSortIconStartOfLine(boolean)"

DataGrid / CellTable: ValueChangeEvent from CheckBoxCell in a custom built header

[Alex opn]

Hello folks,

I've encountered a problem with a 
CheckBoxCellin
 a custom built header for a 
DataGrid
.

What I've done is adapting the 
CwCustomDataGrid-exampleto
 my needs and adding a "Check all"-column in the header. I'm using the 
CheckboxColumn implementation from the accepted answer from here: ->> 
StackOverflow
 

This is how I add the valueChangeHandler to the column in the constructor 
of my CustomHeaderBuilder:

> checkboxHeader.addValueChangeHandler(new ValueChangeHandler() { 
> // TODO: Fix, does not work :-/
> @Override
> public void onValueChange(ValueChangeEvent event) 
> {
> final boolean selected = event.getValue();
> ...
> }
> });
>

I've also tried several other places to register the handler before and 
after the construction of the CustomHeaderBuilder without any effect.

The strange thing is that the CheckBoxColumn works flawlessly when not 
using a custom built header. But the problem is that the column is not 
propagating any events when used in combination with an 
AbstractHeaderOrFooterBuilder
.

I debugged a lot already and can confirm that the handler gets registered 
correctly and the column-instance used is definitely the same all the time.

Anyone has an idea what could prevent events from Cells / Columns in custom 
built headers / footers?

Thanks
Alex

I can't belive I haven't seen the setCellStyleNames method! : ) Thanks for

Re: DataGrid with a Frozen Column?

[Alex opn]

I haven't tried the TableBuilder yet but if it's possible it's by using it 
imo. Have you had a look into the 
CustomDataGrid-Example?
 
As I'm currently working a lot with DataGrids I can maybe tell you in some 
time : ) Right now I have only used Header- and FooterBuilder which can be 
fun, once you get how they work :-P

Re: GWT 2.5 RC2 EntityProxy Validation

[Alex opn]

I just tried to implement clientside validation like that and ran into the 
problem that I get "Incompatible return types" for @OneToMany etc. 
associations as one has to use the Proxy types as return types in the Proxy 
interfaces and the Entity interfaces in the Entity interfaces. Anyone has 
an idea how it could be possible to get around that? :)

What you can do is use an async data provider if you show your tree 
structure through a celltree or a cellbrowser. But that introduces other 
problems. It's not that easy to refresh the data or traverse the tree to 
open all nodes or similar things. I'd really like to provide an example for 
an async data provider but don't have the time now.

Re: How to update GWT CellTree data model preserving the node open states?

[Alex opn]

Sorry for asking so late, I didn't see your answer until now.

Do you use an async data provider? Because I had problems once with an 
async data provider and code like this:

// Expand previously expanded metaspaces

for (int i = 0; i < rootNode.getChildCount(); i++){

final String nodeName = (rootNode.getChildValue(i));

if (expandedNodes.contains(nodeName)){

rootNode.setChildOpen(i, true, false);

}

}


I see that you only seem to have one level under the root node. But what if 
I have more levels? The deeper nodes would not open up as the childs had to 
be fetched and the loop was too fast or something like that. I wish there 
was a clean way to refresh an async celltree somehow. Maybe I just have not 
discovered it yet : )

Sorry for double post : ) Forgot to say that using the snapshot indeed 
solved the problem.

Re: ValueListBox Editor decorator

[Alex opn]

This is my approach:

https://gist.github.com/3425954

As you can see its basically a copy of the ValueBox decorator but with <
TakesValueEditor> as generic type (Had no time to clean it up yet so 
don't wonder about the wrong JavaDocs). Don't know if it's a good approach 
but it works for me so far.

Editor Framework and Multi Select Listbox

[Alex opn]

Hello all,

I tried to implement a "MultiSelectValueListBox" based on the 
ValueListBoxbut
 I did not come far. Not even worth posting my messy code here :)

I hope anyone has done this already and can help me out on how to start or 
give some ideas how to approach this. I quickly ran out of ideas.

I am wondering why this is not shipped with the Editor Framework anyway and 
why no one seems to need this functionality? Googled a bit and only found 
one question on Stackoverflow regarding this. [1]

[1] GWT ValueListBox: can it support more than a single 
selection?

Regards
Alex

I know it's a pretty old thread but I just stumbled upon

code. Are there any news about a patch for this or other suggestions how to

Re: URL for GwtDevPluginSetup.exe is broken

[Alex opn]

Had the same yesterday, was able to download it from svn:

http://google-web-toolkit.googlecode.com/svn-history/trunk/plugins/ie/prebuilt/gwt-dev-plugin-x86.msi

I think with the above you get the newest available?

Also possible to add a specific revision (r10267 in this case):
http://google-web-toolkit.googlecode.com/svn-history/r10267/trunk/plugins/ie/prebuilt/gwt-dev-plugin-x86.msi

taken from:

Set title on specific dates in DatePicker

[Alex opn]

Hello,

I'd like to be able to to set some text as title (which show up when a user 
hovers over a specific date) on some dates of a datepicker similar to the 
addStyleToDates-method:

http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/datepicker/client/DatePicker.html#addStyleToDates%28java.lang.String,%20java.util.Date%29

As I can't find a method for that I think it's not available out of the 
box, right?
Anyone ever implemented this functionality or something similar, are there 
problems extending DatePicker?

Regards
Alex

Re: Exception adding Items to ListBox in IE8

[Alex opn]

Thanks alot for the hint! Indeed I'm using html5shim but would have never 
thought that its causing the problem!

It's working now when I remove html5shim.

You made my day : )
