Hover Text over HTML
I'd like to have some hover text appear over some HTML text being displayed in a Grid table. I have this vague memory saying that you could call setName on a Widget, and that would create hover text for the Widget. But since I can't find a Widget "setName" routine, clearly that memory is incorrect. What is the best way to have hover text over an HTML string?

GWT Custom Serialization
I am having a slight problem with a framework I am making. Here is an
example class:
public class Example implements IsSerializable
{
private final int a;
private final int b;
public Example(int a,int b)
{
this.a=a;
this.b=b;
}
// getters ...
}
A very simple class. However, there is no way to serialize it using
GWT. Although the simple work-around is to remove the "final"
attribute from the fields, that does not "jive" with, what I consider,
solid programming. The "final" attribute means that no where, in any
instance of the class or any instance of a descendant of this class,
will the values of "a" and "b" be modified in any way (exception:
using Java reflection). More than the optimization that many JVMs will
do, there is also a type of safety - the programmer cannot
accidentally put the reference on the left hand side of an assignment
operator.
The GWT compiler will emit a warning that the final fields will not be
serialized. Using the "_CustomFieldSerializer" is also impossible
because the deserialize method takes an instance of the class you are
deserializing as a parameter - instead it should have the return value
as an instance of the class.
So, other than removing the final attribute, has anyone had any luck
side-stepping this issue? Anyone know of any bug reports or
enhancement requests for this (I have searched, but have come up
empty).

Setting id for record @DataTransferObject
Hello - is it possible to set the id for a @DataTransferObject instead

to add the setter setId() but this fails with
'The type UserRecordImpl must implement the inherited abstract method
UserRecord.setId(Long)'
Here is the DTO:
@DataTransferObject(com.eventismo.server.domain.User.class)

// next line causes exception, ambiguous field as declared in
the Record super type
//Property id = new Property("id", "User Id",
Long.class);
Property userName = new Property("userName", "User
Name", String.class);
...
String getUserName();
void setUserName(String userName);
// fails
void setId(Long department);
// And here is the calling code
RequestObject requestObject;
userRecord = (UserRecord)
requestFactory.create(UserRecord.class);
requestObject = requestFactory.userRequest().persist(userRecord);
UserRecord editableUser = requestObject.edit(userRecord);
editableUser.setUserName(name);

GWT panel for HTML UL/LI lists
Hi, for my current GWT project I wanted to make more use of HTML UL/LI
elements than the table based layouts that you normally use in GWT
applications.
Biggest advantages for me is that other people can make changes to the
layout/design of the page without having to touch the code itself.
I couldn't find a class in GWT or anywhere else that helps with that,
so I wrote my own. I can now create HTML like this:
Widget A
Widget B
with this code:
UlListPanel ulList = new UlListPanel();
ulList.addStyleName("sampleList");
ulList.add(widgetA);
ulList.add(widgetB);
For the code go here:
http://markusbraindump.blogspot.com/2010/09/gwt-panel-for-html-ulli-lists.html
Or did I reinvent the wheel?

GWT Widget List/Documentation
I am starting to learn GWT, and I am having trouble finding a list of widgets and how they work. I am looking for a comprehensive list of widgets, preferably including an overview of how they work. I see that there are widgets listed at http://code.google.com/webtoolkit/doc/latest/DevGuideUiWidgets.html, but even that set seems only be a handful of examples. The examples seem to contain additional widgets that I cannot find a good listing of. For instance, the DynaTable example uses the DynaTableWidget and the DynaTableDataProvider, but searching for 'DynaTableWidget' or similar terms retrieves the example code or the source code from docjar.com, but not a more general overview. Can someone give me a pointer to appropriate documentation? Thanks, Al -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

C is still faster than PHP and lighter than Java (although you might come up with better system-level languages, like Google Go, Rust, or D).

How to slow down JavaScript execution (in Firefox)?
Hi all, I'm trying to run integration tests and one of the things I'm trying to test is that various status messages are displayed in the right order. The problem is that everything runs so fast that certain messages are not displayed long enough for Selenium to pick up. :-) That makes the test fail because it thinks steps were skipped. Another example is disabling a button after clicking on it and enabling it after some action has been executed. Again, JavaScript runs so fast that the disabling of the button is never noticed by Selenium. Does anyone know of a way to slow down JavaScript execution? I'm using Firefox for the integration tests so feel free to list Firefox specific solutions.

FlowPanel - Children are added from right to left #-)
Hi,
I have realized a "button bar", i. e. a horizontal bar that contains
buttons, as a FlowPanel (not a HorizontalPanel, to be with standards
mode). The buttons are aligned to the right (float right).
However, when I add buttons, they are added from right to left, i. e.
the first one is at the right and the last one is at the left. I
expected that new widgets are appendet at the right?
I have tried a lot, but nothing changes the behavior.
Any ideas?

Re: Spring Roo & 2.1 M3, not recommended if you haven't tried.
I just finished a project on Roo but we were using Spring also for front end. What we figured out is that Roo is very good to generate that initial structure and than better be on your own. We still used roo to manage the domain entities (generating getters and setters) but not more than that. Now I am in a project with GWT and Spring. From my earlier experience we generated the initial code structure using roo and than we are on our own. Also I would second Daniel about UIBinder.

Re: Reverse proxy problem once again
Thanks Sebastian, actually that is what I already did meanwhile :-) I thought I was supposed to keep the contextpath (it's a project for my work), but now they are fine with redirecting from / to /bla on the proxy, where bla matches the contextpath on the tomcat, so now it works without any other adjustment. I also had a workaround, where I overrode RemoteServiceServlet and modified the transmitted URL accordingly, that worked as well...

Kevin, My experience with Roo is not much better than yours. I was able to get it running after an hour or so. It is an early stage product that shows potential. Not ready for prime time yet. Regarding UiBinder: If it turned you off 'immediately' as you said, you have not created enough widgets in GWT yet, because once you'll have done that, you'll see that creating widget UI in XML with UiBinder is the simpler and more efficient way.

Re: Reverse proxy problem once again
Hi pete, I got along quite well with mapping localhost:80/bla/ to localhost: 8080/bla in the httpd.conf - i.e. keeping the context path as it is. No more action is necessary then. (you could set up a redirect rewrite rule for path / so the user gets forwarded). This is the most simple solution I know. Maybe (I'm not sure now), you could rewrite the context path as well with mod_rewrite but that's no more than a vague guess. Otherwise, you'd indeed have to overwrite doGetSerializationPolicy on the servlet which is just what you don't want.

Spring Roo & 2.1 M3, not recommended if you haven't tried.
I think most gwt developer who watched the demo of Spring Roo in Google IO video would be interested in giving "the expense-tracking GWT project under 200 keystrokes" a try. However, that 200 keystrokes took me almost a day to put into debug mode. (if you also got stuck and would like too know how to get through, give me a shout) Anyhow, I got it running. But there are so many drawbacks that I encounter. Maybe there are some other way round, but there are virtually no documentations. Isn't spring roo supposed to accelerate code formation? But it seems that it's trying to waste as much time as they can to slow you down. I have to admit that I don't know much about spring / roo / maven (nor i'm a java expert). So please point it out if I made the wrong claims. 1. Roo generated everything into UIBinder. i think why most people invest their time into GWT because it's Java. We are more familiar with Swing type of development rather than HTML. And Uibinder just turns me off immediately. I bought a license of GWT Designer before Google bought the company. I believe this acquisition implies that GWT will stick onto Swing type of UI development. But on Roo project, GWT Designer is rendered totally useless and what you can see are window internal errors. 2. I think others have also complained that whenever you made changes to the domain objects, all your custom changes on the UI will be lost. Maybe there are some other ways to get around with it, but there is no documentation telling me how to do it!! 3. In Ruby On Rails, all the codes you see after scaffolding or raking are just what you need to see. But Roo will generate a hell lot of codes which you don't know where you should touch and where you shouldn't. I spent hours watching videos from Google IO trying to understand what does all those new factories / activities / renderer mean. But sorry, i just can't follow all those fancy flowchart. But why don't you put them into some documentation so that I can follow them at my own pace? 4. Seems that the code generator or gwt plugins on STS are still having some bugs. Some of the viewbinder doesn't have the corresponding ui.xml generated. (maybe there are omitted for good reasons). And @UIField are shown missing even they are actually there. I think another important reasons of choosing GWT instead of other framework is because of the error detection mechanism. You can root out most silly errors with the IDE because all errors are underlined in red. Now you got those red lines in almost all files in the scaffold.generated source folder. So you just turn a blind eye to those? 5. Maybe it's just me. Annotation is just not my cup of tea. I don't know how many of them, their usages or even how to spell them. And there are just too many of them with uibinder and roo. Those scaffolding and data binding in 2.1. looks intriguing. , but gonna go back to do some real work with GWT 2.0. I just hope the release of 2.1 will turn out to be much better documented. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Datastore
Hi Trevor, I would suggest giving also a try to Objectify which a layer on top of raw Datastore: it makes access to data much easier and has a lower learning curve than JDO. See http://code.google.com/p/objectify-appengine/ (have a special look at wiki pages) I moved away from JDO for Objectify and I am very satisfied with it. didier On Sep 24, 5:17 pm, David Chandler wrote: > You can use any of GWT's client / server protocols to connect to a > servlet running on App Engine that in turn calls the Datastore.
