How to use image in global css
Below is my code:
public interface Resources extends ClientBundle
{
@NotStrict
@Source(Global.css)
CssResource css();
}
@Override
public void onModuleLoad()
{
Resources resources = injector.getResources();
resources.css().ensureInjected();
}
//Global.css
.rule1{
background:url(images/img1.png);
}
If referring images like,as you can see in rule1,
background:url(images/img1.png);(images directory is under war
directory),img1.png can't be loaded properly in dev mode,but it got
loaded in web mode.So Question are: 1, how to use image in this
Global.css? 2,Is it possible to use image sprites here?

Re: Difficulty to run simple GWT application
Hi Sebastian, i am creating application as you suggest but when i deploying it on tomcat server then it shows resources ins not available.so now what should i do? help me . Thanks Rahul On Apr 26, 7:38 pm, Sebastian Gurin sgu...@softpoint.org wrote: Hi Rahul, this is what I shlud do for getting started. first of all do not use tomcat yet, first feel confortable with the GWT+eclipse 1) File-New-(Google)New Application proyect - create your gwt web application project. Here use Google Web toolkit only, don't use Google App engine yet. That will create you a new project with some interesting things: a) your.proj.YourProject.gwt.xml - this file is called a gwt module definition. b) packages client, shared, server c) a root folder named war with a html file inside. This war folder is the web application folder (what you put inside webapps in tomcat - but not yet.) in client package that is where your java that will be translated to javascript by gwt are, there is two Greeting* classes (dont worry about these yet) and a third class named YourProject.java (or whatever name you give to your new project). thi s class is your entry point. the project has a sample applicatoin ready to be executed, right click on your.proj.YourProject.gwt.xml and run as Web application. The Developer mode view will be shows and after the app is loaded, it will show you an url likehttp://127.0.0.1:/Test12.html?gwt.codesvr=127.0.0.1:9997. Open this url with firefox (version =10) or with chrome. It will ask you to install a browser plugin, do it. When the plugin is installed reopen that url and you will be executing your sample webapp using the GWT hosted-mode. You can make changes in the java sources, save then and reoloading the page will reflect the changes. Try to change something... Now what about putting all this on a tomcat? its easy, first compile your project like this: ijn package explorer view, right click your new project - Google - GWT Compile... - compile. When this is finish, GWT will put in war the entinre webapp. just copy or link the war folder to your tomcat's webapps folder and rename it acordingly, for example, yourproject. Start tomcat and go tohttp://localhost:8080/yourProject/yourProject.html. I have ant scripts for doing all this with ant if you want I can share. hope this can help you ...

Please recommend table widget to display a number of similar widgets
Hi everybody. I need to display a big amount(1000+) of similar widgets (each widget contains photo + descrption - about 400*400 px total) in a table - say, 10 rows and 2 columns per page. I don't need option to select, drag, highlight or do smth else with these widgets - just display them. It seems that FlexTable doesn't support paging. CellTable does, but it seems to be too complicated and best suited for displaying different data in different columns while I need just to place similar widgets in each cell. So, I'm a bit confused about what table to use and need some help about this. Thanks in advance! -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Preventing selection event propagation
Our application has two tabs. On selecting the tabs we have to display a confirmation window(dialog box). Depending on whether user clicks Yes or No button in the confirmation window, the tab selection event should proceed or stop. I know we have event.stopPropagation() method for click event. However there is no such method for selection event. Is there any work around to stop the propagation of the selection event. Any help is much appreciated.

Thoughts on User defined time in the UI
I would like to have a field in my UI which allows the user to pass a 24h time - I will then use the time to do a search on events occuring after that time. There should not be a date asociated with the time on the UI. The time passed should be in the format hh:mm:ss. I'm using plain ol' GWT - extensions or addtional libraries are unavailble here for all intents and purposes (I've seen a few options in gwt-ext and smartGWT but would rather avoid. What would be the best method of allowing users to define time in the UI using core GWT? A textbox which assumes 6 digits (hhmmss) that can then be parsed? Three seperate text boxes for hour minute second which would be easier to validate? Extending a Calander Widgit? Another Widgit I've overlooked that should be considered? Or something I haven't considered at all? Thanks for your help -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Is there any way to solve this problem?
Here is my code :
RequestBuilder request = new RequestBuilder(RequestBuilder.GET, url);
request.setHeader(Content-Type, text/html);
RequestCallback callback = new RequestCallback() {
@Override
public void onResponseReceived(Request request, Response response) {
String userIdentity = response.getText();
}
@Override
public void onError(Request request, Throwable exception) {
exception.printStackTrace();
}
};
request.sendRequest(null, callback);
Please anyone kindly help me to solve this problem.
Thank you.

Dynamic CompositeCell
The title is too short, let me explain and simplify my situation. Say, I have a dto which contains a list of Booleans. I need a column whose cell looks like below: item_1 checkbox_1 item_2 checkbox_2 ... item_n checkbox_n If n is a fixed number, it is fine to use CompositeCell. The problem is we don't know the size of list and each cell can have different list size. Is there any way to extend CompositeCell so as to make it support my situation. Or maybe I should write a new Cell? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT The type XXX is already defined error on package-private classes with NO previous definition.
Since I spent some time searching for a solution, here it is. Don't put top
level classes like this:
public class1{
}
class2{
}
Although it's a valid java syntax, GWT doesn't seem to handle this very
well. That's what it should look like:
public class1{
static class2{
}
}

GWT applications session management

Can someone explain the authentication logic in GWT apps ? Anyone explain the entire authentication and authorization logic in Ajax application ? Session management in Ajax applications ?

Clear queue method invocations on RequestContext
To perform a save in a view I am using the RequestFactoryEditorDriver to flush any changes to a RequestContext and then I call save(the edited proxy).to(MyReceiverVoid).fire(); MemberRequest s = (MemberRequest)editorDriver.flush(); MemberProxy sectorProxy = (MemberProxy)getProxy(); s.saveMember(sectorProxy).to(new MyReceiverVoid()).fire(); MyReceiver has a onConstraintViolation method which displays violations generated in the server. I am using my own ServiceLayerDecorator.validate() to check for any business-related constraints. To this point it works fine. However when after more than one attempts the user finally fixes all violations and the entity reaches the service layer, the save method is invoked multiple times (as many attempts it took to pass validation). I understand that this is because the request context is queuing all method invocations and by calling onConstraintViolation. this queue is not cleared. As a result, when it passes validation there is a number of onvocations for saving which all then succeed in inserting to the database. My question is how/where to clear the request context of any method invocations that have lead to the call of onConstraintViolation so the save to the service layer is called once only. thanks in Advance Alex -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Compile Gin-enabled GWT application with ant
I find the answer. Modify classpath by adding your compiled GWT classes
(that's why GWT compiler could not found it), because GIN needs class files
to compile successfully.
classpath
pathelement location=src/main/java/
pathelement location=${classes.dir}/
path refid=classpath/
/classpath
It helps to me.

Request Context clear queue on method invocations when onConstraintViolation is called
To perform save in a view I am using RequestFactoryEditorDriver to flush any changes to a RequestContext and then I call save(the edited proxy).to(MyReceiverVoid).fire(); MemberRequest s = (MemberRequest)editorDriver.flush(); MemberProxy sectorProxy = (MemberProxy)getProxy(); s.saveMember(sectorProxy).to(new MyReceiverVoid()).fire(); MyReceiver has a onConstraintViolation method which displays violations generated in the server. I am using my own ServiceLayerDecorator.validate() to check for any business-related constraints. To this point it works fine. However when after more than one attempts the user fixes all violations and the entity reaches the service, the save method is invoked multiple times (as many attempts it took to pass validation). I understand that this is because the request context is queuing all method invocations and by calling onConstraintViolation. this queue is not cleared and this leads to multiple calls to the server. My question is how/where to clear the request context of any method invocations that have lead to the call of onConstraintViolation thanks in Advance Alex -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Can UI components be tested through JUnit/GWTTestCase?
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
I've been able to test Widgets with JUnit in a project I'm working on.
I'm able to make widgets, see that they respond to external events
(notifications about state they observe, or event types they're
subscribed to via an EventBus, that sort of thing), and even send UI
events to them:
final MyWidget myWidget = new MyWidget(...);
myWidget.someButton.fireEvent(new ClickEvent() { });
//assert that the right things happened
The anonymous subclass of ClickEvent feels a little hacky, but it works
for us because our widgets (for the most part) just care that they got
clicked, they don't care about x and y coords, etc etc.
Writing the tests was relatively straightforward, but getting them to
run as part of a Maven build took some doing. A pom with all the
necessary incantations is here:
https://open.med.harvard.edu/svn/shrine/trunk/code/webclient/pom.xml
I don't know if that's minimal or not; I started with what was generated
by the gwt-maven-plugin, and tweaked the pom until it did what I wanted.
:/ We use a TestSuite (ugh) and follow the naming conventions for test
classes and suites recommended by the gwt-maven-plugin docs.

Ok, I found some old messages (several years old) that says this
cannot be done.
However, when I look at:
https://developers.google.com/web-toolkit/doc/latest/DevGuideTesting#DevGuideJUnitSetUp
this seems to imply that you can actually test GUI items on a browser
with such tests. I might well be completely misinterpreting what it's
there for, though.
However, I'm baffled as to how to do so.
For example, I might normally put MyWidget into the RootPanel as
follows:
RootPanel.get().add(new MyWidget(Some text here));
But how would I do this in a JUnit test case / GWTTestCase?
Thanks.

Re: Preventing selection event propagation
Tab(Layout)Panel's SelectionEvent is a GwtEvent and not a DomEvent, so its only a logical event fired by GWT and not a native event fired by the browser. Thats why you don't have a stopPropagation() / preventDefault() method. But TabPanel and TabLayoutPanel have an addBeforeSelectionHandler() and the BeforeSelectionEvent contains a cancel() method which should cancel the upcoming selection. This should help you to solve your problem. -- J. Am Freitag, 27. April 2012 13:45:19 UTC+2 schrieb ALB-PSP-DV1: Our application has two tabs.

Re: Request Context clear queue on method invocations when onConstraintViolation is called
Don't enqueue requestContext.saveMember(..).to(..) in the save button ClickHandler. Do it once when you start editing the proxy and in your ClickHandler you only need to do editorDriver.flush().fire(). -- J. Am Freitag, 27. April 2012 12:32:28 UTC+2 schrieb Alex Vakaloudis: To perform save in a view I am using RequestFactoryEditorDriver to flush any changes to a RequestContext and then I call save(the edited proxy).to(MyReceiverVoid).fire(); MemberRequest s = (MemberRequest)editorDriver.flush(); MemberProxy sectorProxy = (MemberProxy)getProxy(); s.saveMember(sectorProxy).to(new MyReceiverVoid()).fire(); MyReceiver has a onConstraintViolation method which displays violations generated in the server. I am using my own ServiceLayerDecorator.validate() to check for any business-related constraints. To this point it works fine. However when after more than one attempts the user fixes all violations and the entity reaches the service, the save method is invoked multiple times (as many attempts it took to pass validation). I understand that this is because the request context is queuing all method invocations and by calling onConstraintViolation. this queue is not cleared and this leads to multiple calls to the server. My question is how/where to clear the request context of any method invocations that have lead to the call of onConstraintViolation thanks in Advance Alex -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to stop the move to Place
Hi: I am not 100% sure what you are trying to do, but in your current activity, you can override mayStop(). That would be one possible way to intercept and potentially cancel going to a new place.

Re: How to add External Java Classes to GWT Project?
Danish:
Your project out of the box was created by the plugin with a directory
structure as follows:
/client
/shared
/server
The class you created will reside under the server package. Anything
in the /client and /shared will eventually get compiled down to JS. So
in your server you do all your crud operations and return data back to
the client.

Alfredo

Re: Dynamic CompositeCell
If you have an n number of values that should be represented in one single column, I would go for a tree. Its ability to expand nodes when needed, gives the user a chance to have it expanded or collapsed.

Re: Thoughts on User defined time in the UI
I don't recall seeing a TimePicker in GWT. I do recall seeing one and I found it in the GWT incubator (URL at the end of my response). Options: a) Create something fairly simple now to get the job done. Three SelectionCell's if you want the values to be unmodifiable and save yourself the trouble of validation if you used TextBoxes. This is perhaps one of the simplest ways to go. b) Create something a bit more sophisticated. c) Take a look at the previous incubator implementation. It's GWT only, so you might be able to resuscitate it and use it. http://code.google.com/p/gwt-incubator-lib/source/browse/trunk/GWT-Incubator-TimePicker/src/main/java/com/gwtincubator/widgets/client/timepicker/TimePicker.java Regards, Alfredo On Wed, Apr 25, 2012 at 11:56 AM, GlasgowSteve shsp...@gmail.com wrote: I would like to have a field in my UI which allows the user to pass a 24h time - I will then use the time to do a search on events occuring after that time.

Re: How to stop the move to Place
The situation is the following: 1) There is a table cell which can be edited 2) the user has not saved the changes, and clicks on any item on the navigation menu (try to move to another page) 3) You receive a modal window with the message - There are unsaved changes. Do you want to keep them? There are three buttons - Save, Do not Save, Cancel 4) By clicking the Save button, the data is sent to the server and takes you to a page that the user has selected previously on the menu 5) If the button is pressed, Do not save just takes you to a page that the user has selected previously 6) If you press Cancel modal window just closes, switching to a different page is not carried out I'm sorry to write in English until I get bad, so to understand my speech can be hard :) пятница, 27 апреля 2012 г., 17:36:58 UTC+3 пользователь Alfredo Quiroga-Villamil написал: Can you please provide the flow for this particular case.

Re: Thoughts on User defined time in the UI
Check out how this is done in ExtJs. Basically you just set a listener for
the character entry to the textbox. You set a regex that is looking for
something like *\d{1,2}:\d{2}:\d{2}* to confirm that people are entering it
as desired. Then I just have 2 functions called sec2time() and time2sec()
so that I can pass the time as seconds back to the server.
This is how I do this for time entry on
RunPartner.comhttp://www.RunPartner.com,
but you've have to be a member to play with that widget. I'm working on
converting it to GWT, but it's still ExtJs for now. I'll throw the time
widget source up when I get it in GWT.
Sincerely,
Joseph

Re: How to use image in global css
To start with, I like to utilize the public/ folders in my packages for
storing these values. That way, if you put images in any public/images/
folder (I put a public/ folder in every module), they will end up in your
war in the images/ folder.
First make sure that the above is working correctly for you. You can also
utilize an ImageBundle which will assure you the images are available
through compile time checking. I find this the best solution.
With an ImageBundle your rule becomes:
@sprite
.rule1 {
gwt-image:'img1';
}
To investigate this further use FireBug or Chrome dev tools to find what
image resource your .rule1 is pointing at. That will probably reveal the
problem.

Joseph

Re: Runtime exception: com.google.web.bindery.requestfactory.server.UnexpectedException: Could not find static method with a single parameter of a key type
You do have to read the doc carefully indeed. I got stuck for a little while, I thought I could get away by simply using find but no you need to use findEntity, ie replace Entity by your entity name. This got me, because at first it worked with a single entity, but when I had two entities with relationships, it wouldn't work anymore. By changing the method names to respect the convention mentioned above, it worked fine.

Re: UIBinder: Overriding obfuscated CSS styleNames
On reading your problem, I became curious how this is achieved.
According to the following article, you can do this using the interfaces.
http://stackoverflow.com/questions/5943895/how-exactly-would-one-override-a-cssresource
So, you'll need to use the interfaces in your UiBinder.
Something like:
# put this in your new widget's java class
interface CustomStlye extends ToggleButton.Style
{
@Override
public String down();
}
# put this in the UiBinder of your new widget
ui:style type=com.mypackage.CustomStyle
.button .down {
background: #fff;
}
/ui:style
Let me know if this works for you. I don't have the time to make a module
to test this on?
Sincerely,
Joseph

Re: where to place css file and image file?
For CssResource and ImageResource users, I find this the most robust way to place these files: *com.myPackage.moduleA.resources (put resource interfaces here) *com.myPackage.moduleA.resources.images (put image files here) *com.myPackage.moduleA.resources.css (put css files here) The real payoff here is that: 1. Each module is self contained with all its css/images. Try pulling a module's resources of out a public folder shared by 10 modules. 2. You can more easily use this module in a different GWT project. 3. Since you're not using a public folder, only the used selectors/images get compiled into your output war. Saves a lot of time/bytes. You might ask What images used in multiple modules? In our apps we have a common module with these parts. Hope that helps.

Re: How to stop the move to Place
Interestingly enough, have to admit, I don't see at a glance unless I am missing something an easy way to accomplish what you need. We need something to completely halt execution and act upon the result of the action/handler (ok or cancel result for example), which is ultimately what the PlaceController is doing via a DefaultDelegate using a Window.confirm in mayStop.

Re: Server detection of client crash
Thanks. I think Joseph said it before and I agree with him. If it's something of that nature, I would likely try to stay from web stuff. However, that doesn't mean is not possible or there are no ways to ensure what you want. I recently had the chance to speak with a few guys at RedHat about a project they have been working on based on GWT. I've been meaning to let people know about it because I was really impressed by a couple of things I saw. One of them can truly help you and make your requirement easier or a lot easier to implement. http://www.jboss.org/errai A few things: a) You don't need jboss to use it. b) Take special attention to CDI (crazy cool and useful). c) They've done something really interesting where you truly have a transparent web/server application, blurring completely the lines between server and UI. Via an annotation you have Server Push. Their Dependency Injection I thought was also nicer than GIN for the UI. Although I use GIN and love it! So what you could do, assuming that you truly want to keep this web based is to have the server contacting the UI every x amount of seconds. If no response is received from the UI, then you know that something is not right. That would be better I think than polling the server. Again, this could be done without errai, but take a look at it if you get a chance.

Please help with CellTable
Greetings, I need a sort of listbox where each row is made up of several columns. I don't want to edit the data in the listbox. I just want to select one or more rows, click a button, and be able to know which rows were selected. Looking around it seems like CellTable is close.

Re: Please help with CellTable
Hi Blake:
I will try to take a look later at 1 and 2, they are CSS controlled.
For now:
4. See below for an example:
MultiSelectionModelString multiSelectionModel = new
MultiSelectionModelString();
CellTableString cellTable = new CellTableString();
cellTable.setSelectionModel(multiSelectionModel);
3. Handler for the selection model below:
// Handler
cellTable.getSelectionModel().addSelectionChangeHandler(new
SelectionChangeEvent.Handler() {
@Override
public void onSelectionChange(SelectionChangeEvent event) {
SetString selected = ((MultiSelectionModelString)
cellTable.getSelectionModel()).getSelectedSet();
if (selected != null) {
}
}
});
Hope it helps.

Also part of 4 is SingleSelectionModel. So you can either use Single
or Multiple as the SelectionModel depending on what you need.

The class you created will reside under the server package. Anything

I used Issue 51810 as my template for this

I use sinkEvents to catch onPaste events to a TextBox so I can react to
changes on TextBoxes without waiting for it to loose focus. This works well
for IE and Firefox but Opera does not support onPaste.
Opera has an onInput event that provides a way to detect a TextBox change.
This patch allows the onInput event to be detected in GWT.

Looks good, but I must say that I dont' quite understand how/why
this fixes
the
problem. Can you point out how the code execution in this class
would have
resulted in a breakage with a HashMap vs. an IdentityHashMap?
At line 632, a collection is populated with the result of
resolveClientValue(Object,Type), which is always an empty proxy
(properties are
populated later) –modulo reuse of a proxy if it has already been
resolved–. This
isn't an issue with EntityProxies, as each proxy as at a minimum a
stableId that
keys it to a domain object and distinguishes it from other proxies
(for other
domain objects), but ValueProxies compare equals() to each other by
their
properties' values only, independently of the underlying domain
object.
So, when you resolve a collection of ValueProxies, the first iteration
of the
loop (at line 632) creates a new, empty ValueProxy and puts it in the
clientObjectsToResolutions map. In the second iteration,
resolveClientValue will
create another ValueProxy, but will return the same Resolution because
the
ValueProxy compares equals() to the previous one, so getting the
Resolution from
the map will return the one for the first ValueProxy.
Using an IdentityHashMap fixes that lookup, so that we have one
Resolution
instance per proxy instance.
Because we have other guards for EntityProxies (keyed by stableId in
state.getBeansForPayload(), via resolveClientProxy), that change is
safe: the
goal is to have a most one proxy per domain object (which is
guaranteed in
RequestState for EntityProxies)
Ok, thanks for the explanation, that helps a lot. Two things I'd say:
-we need to document this somewhere, because it's pretty subtle
-it seems bad that we can get into states where ValueProxy.equals() is
doing the wrong thing, but I'm not familiar enough with this code to
propose a good solution. I'd just say that it seems like a pitfall if we
need to have an IdentityHashMap to work around issues like this..

AH!!! I did not know that. Thanks again. BTW, I can't read that wave -
can you add me to it?

I mean, when you a do a diff, that should never happen, right? The problem is that autobean has no notion of read only vs. editable beans. That's something specific to proxies and request factory, where getting a property (including from a visitor) will automatically edit its value if it's a proxy. Ugh.

Looks good, but I must say that I dont' quite understand how/why
this fixes
the
problem. Can you point out how the code execution in this class
would have
resulted in a breakage with a HashMap vs. an IdentityHashMap?
At line 632, a collection is populated with the result of
resolveClientValue(Object,Type), which is always an empty proxy
(properties
are
populated later) –modulo reuse of a proxy if it has already been
resolved–.
This
isn't an issue with EntityProxies, as each proxy as at a minimum a
stableId
that
keys it to a domain object and distinguishes it from other proxies
(for other
domain objects), but ValueProxies compare equals() to each other by
their
properties' values only, independently of the underlying domain
object.
So, when you resolve a collection of ValueProxies, the first
iteration of the
loop (at line 632) creates a new, empty ValueProxy and puts it in
the
clientObjectsToResolutions map. In the second iteration,
resolveClientValue
will
create another ValueProxy, but will return the same Resolution
because the
ValueProxy compares equals() to the previous one, so getting the
Resolution
from
the map will return the one for the first ValueProxy.
Using an IdentityHashMap fixes that lookup, so that we have one
Resolution
instance per proxy instance.
Because we have other guards for EntityProxies (keyed by stableId in
state.getBeansForPayload(), via resolveClientProxy), that change is
safe: the
goal is to have a most one proxy per domain object (which is
guaranteed in
RequestState for EntityProxies)
Ok, thanks for the explanation, that helps a lot. Two things I'd say:
-we need to document this somewhere, because it's pretty subtle

Unfortunately, Wave is readonly so I cannot add you to the wave, so I
exported it and mailed it to you.
BTW, with() is documented in

Ok, then we probably need to fix something with respect to getting a property from a proxy - I wonder why getting a value from a proxy implies an edit? Otherwise, you have to pass the RequestContext along with the proxies everywhere. With this auto-edit, you can simply edit the top-level proxy and then use it like any other bean. e.g. proxy = ctx.edit(proxy); proxy.getFoo().setBar(foo bar); // auto-edit vs. proxy = ctx.edit(proxy); ctx.edit(proxy.getFoo().setBar(foo bar); FYI: to fix the TODO about reducing the payload while preserving the no-op request, validate proxies only, I was thinking about tracking those proxies that are auto-edited vs. those that have been explicitly edited, so that only the latter are unconditionally sent to the server; the former being sent only if they contain changes. The issue here is that for now the RequestFactoryEditorDriver explicitly edits all proxies, instead of editing the top-level proxy and taking advantage of the auto-edit feature (see issue 5981 which is related; I do believe it's better that way though: editing proxies in CellTables would break the edit/flush workflow; and that could be mitigated by introducing read-only editors (that wouldn't edit the subproxy)). ...I wouldn't mind personally removing that auto-edit feature, even if that's a big breaking change: it seems like overall it causes more harm than good. http://gwt-code-reviews.appspot.com/1601806/diff/9001/user/src/com/google/web/bindery/requestfactory/shared/impl/AbstractRequestContext.java File user/src/com/google/web/bindery/requestfactory/shared/impl/AbstractRequestContext.java (right): http://gwt-code-reviews.appspot.com/1601806/diff/9001/user/src/com/google/web/bindery/requestfactory/shared/impl/AbstractRequestContext.java#newcode1281 user/src/com/google/web/bindery/requestfactory/shared/impl/AbstractRequestContext.java:1281: assert bean.getTag(REQUEST_CONTEXT_STATE) == expectedState; On 2012/04/27 14:52:12, rdayal wrote: Nit: put parens around the assert expression.
