How to test FlexTable click?
Hi all
I have a click handler method like this in my presenter
widget.getTable().addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
FlexTable table = (FlexTable) event.getSource();
Cell cell = table.getCellForEvent(event);
String purchaseOrderId = table.getText(cell.getRowIndex(),
cell.getCellIndex());
RegisterArrivalEvent arrivalEvent = new RegisterArrivalEvent();
arrivalEvent.setPurchaseOrderId(purchaseOrderId);
eventBus.fireEvent(arrivalEvent);
}
});
How can I successfully test my presenter with a method like this in
it?
Would I be better of rewriting this method all together?

Re: Debugging GWT App in Eclipse
There's a bug in JDK 1.6.0_14 that does this, so check what version of java you are using.

Re: GWT BUG? .. Not transparent handling of special history tokens in GWT 1.6
Instead of:
http://server/app/index.html#index?redirect=encoded original
URL
Try:
http://server/app/index.html?redirect=encoded original URL#index
I also ran into that problem until I realized I was placing the anchor
before the parameters.

In my application, if anonymous user directly visits protectedpage,

The redirection to the loginpageis done with this code:

String path = Location.getPath();
Location.replace(index.html#home?redirect= +
URL.encodeComponent(path.substring(path.lastIndexOf('/') + 1)

After the user logs in, the redirect parameter is parsed by decoding
the value part (encoded original URL) obtained from the
History.getToken() call. Then Location.replace(redirect) is called to
load the original URL.
As you may noticed, the redirect parameter must be composed
differently for Firefox (3.0 and 3.5). Tested also with the Chromium
browser (Linux) and MSIE6. Opera doesn't work, but I haven't done any
more tests for it. The problem was detected with this URL:
http://localhost:8080/gofer/gui/pipeline.html#subchannel-modify?paren...
redirect version of the URL:
http://localhost:8080/gofer/gui/index.html#home?redirect=pipeline.htm...
Is this a GWT bug? I think so :-). Should I report it?

Generation of XML
Hi, My web application has textboxes. User inputs value in these textboxes and I am required to generate an xml out these values. Each textbox has a label and I would be using the label text and the textbox text in my xml. The XML has some mandatory fields which i need to specify for each xml and then according to the textbox text i need to modify my xml for each run. This is how I think this would be done. The textboxes and labels are on the client side, once the submit button is submitted I would be sending these values to the server via RPC. But then what to do ? I am new to this. So can anyone tell me how this can be done in gwt. Some tutorials would also be very useful.

I have an app that involves long run times on a server (scientific
app). I ported to GWT specifically to give better user feedback on
long jobs (e.g. progress bar, email results option, etc.).
I have to control threads on the server side, in my RPC services, in
order to avoid memory issues in tomcat due to the size of the jobs
this app runs on the server. When a big job is running, subsequent
jobs can be submitted, and a GWT Timer polls the server periodically
to check on status and let the user know. When a big job is running,
subsequent jobs start to generate errors after a while, and the
Throwable that comes back to the onFailure() is either NULL or it's
message and stack trace is also NULL.
Eventually I'll get a strange script stack over flow. The code is
very simple: I start a timer when a job is submitted, and schedule it
to run in a few seconds. The Timer calls a checkJob() method that
calls an RPC service and reschedules the timer to run again if the job
is not finished. On the server side, all the service is going is
returning a simple object that encapsulates the job and it's progress.
Here is a log I keep on the client side:

Re: How can you detect a mouse double click on a text box?
Hi Rahul,
A couple of options:
Option 1:
Extend TextBox and use the native DoubleClickEvent as follows:
import com.google.gwt.event.dom.client.DoubleClickEvent;
import com.google.gwt.event.dom.client.DoubleClickHandler;
import com.google.gwt.event.dom.client.HasDoubleClickHandlers;
import com.google.gwt.event.shared.HandlerRegistration;
import com.google.gwt.user.client.ui.TextBox;
public class CustomTextBox extends TextBox implements
HasDoubleClickHandlers {
public CustomTextBox() {
super();
}
@Override
public HandlerRegistration addDoubleClickHandler(final
DoubleClickHandler handler) {
return addDomHandler(handler, DoubleClickEvent.getType());
}
}
To to test your requirement:
final CustomTextBox textBox = new CustomTextBox();
textBox.addDoubleClickHandler(new DoubleClickHandler() {
@Override
public void onDoubleClick(final DoubleClickEvent event) {
textBox.setText();
}
});
Option 2:
Increment a clickCount variable inside a ClickHandler. Start a Timer
on the first click which resets the clickCount after a certain
timeout. If the click count is = 2 on any click then you have a
double click. Obviously this is not as good as Option 1 since you have
to use your own double click timeout which may be different to the
user's operating system setting.
Hope this helps.
Cheers,
Paul.

Re: Hint: Previous compiler errors may have made this type unavailable
I don't know if this will help, but check your paths. If you have a source path like this: C:\Workspace\App\src\com\me\app: - App.gwt.xml - App.java Where App.gwt.xml reads: ?xml version=1.0 encoding=UTF-8? !DOCTYPE module PUBLIC -//Google Inc.//DTD Google Web Toolkit 1.7.0// EN http://google-web-toolkit.googlecode.com/svn/tags/1.7.0/distro- source/core/src/gwt-module.dtd module rename-to='app' inherits name='com.google.gwt.user.User'/ inherits name='com.google.gwt.user.theme.standard.Standard'/ entry-point class='com.me.app.App'/ /module You will get an error like this: Compiling module com.me.app.App Computing all possible rebind results for 'com.me.app.App' Rebinding com.me.app.App Checking rule generate-with class='com.google.gwt.user.rebind.ui.ImageBundleGenerator'/ [ERROR] Unable to find type 'com.me.app.App' [ERROR] Hint: Previous compiler errors may have made this type unavailable This is because GWT is (very) not smart, and cannot locate classes in the small path as the gwt.xml file (notice how the template projects always have a client and server directory). So fix this, change the class path of App.java to: C:\Workspace\App\src\com\me\app\client And the entry point to: entry-point class='com.me.app.client.App'/ This may not be the problem you have, but it sounds quite similar.

Re: Widget.clear() method not clearing properly
Hi Thamizharasu.
Panel.clear() does only remove child-widgets. As the innerHTML 'sample
content' is not considered a widget, it won't be affected.
You may do the following to completely clear the contents of your div
element:
---*snip*---
RootPanel samplePanel = RootPanel.get(sample);
// Clear
Element element = samplePanel.getElement();
NodeListNode childNodes = element.getChildNodes();
for (int i = 0; i childNodes.getLength(); i++) {
element.removeChild(childNodes.getItem(i));
}
---*snip*---

Phil

This is adding my new widget. But not clearing my old content (sample

Re: Which use for CSS?
Using horizontal and vertical panels is the prefered way of realizing layouts in GWT. You shouldn't try to implement your layout from scrach. But this doesn't mean, that there is no need for CSS in GWT. GWT should also prevent you from many browser differences, but that doesn't mean, that it will do allways.

If you look to the Showcase app ( http://gwt.google.comsqf/samples/Showcase/Showcase.htmlhttp://gwt.google.com/samples/Showcase/Showcase.html), it's using different themes and the switch is done by changing the CSS file, which provides colors, borders, etc. There are lots of other examples, like creating a Dialog, which lays over the rest of your app. The differences of CSS in different browsers is a common problem, but most webdevelopers know how to work around. In GWT this also means, that defered binding allows to create different implementations for different browsers. Another point, you should care about, is, how do you create margin or padding without CSS? In other GUI frameworks like SWT, you've got layout constraints, that can be applied to a component, but in GWT, you don't have. CSS is the prefered way to do.

DisclosurePanel and registered event handlers
Hi, I'm using a DisclosurePanel and have registered an onClose-event- handler and an an onOpen-event-handler. In these handlers I want to store the status of the panel (open or closed) with an rpc method on the server. This part is working. In the second part I want to open or close the panel with his setOpen method due to the open status on the server. But the setOpen method fires the onOpen or onClose events again and changes the status on the server. Is there a way to decide, if the source of the event is a mouse click or the setOpen method? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Eclipse plugin for Eclipse 3.5 (Galileo)
None of the plugin developers has made an announcement or offered a release date. They have responded to questions from anxious developers eager to see the new version by offering their own hopes or expectations for delivery. That's more then you get from many projects, partially for the very reason we see here: when those aspirations aren't met, people who interpreted them as official commitments start complaining. I shouldn't have to haul out my soap box here. Have a little patience and put this in perspective. You are not paying customers and no one here is under any obligation to you. If you want hard delivery dates and commitments, get out your checkbook and see if anyone bites. A polite how's that coming along inquiry is, I would think, an appreciated sign of community interest. But if you want to sit in the back seat and yell are we there yet at the drivers, either accept that soon is a valid answer or, if you're lucky enough to get something more precise, understand that it's somebody sticking their neck out trying to be helpful.

Re: Problems with hosted mode
Actually, it is not necessary that the script tag be placed in the head section. You can place it in the body section. GWT's samples actually place the script reference in the body.

Google plugin for eclipse3.4 launches GWT hosted mode with deprecated GWTShell
I am using GWT in an existing web application that has a web folder called 'WebRoot', so the configuration looks like this: [project]/WebRoot/WEB-INF/web.xml When running in hosted mode the deprecated GWTShell is used apparently because it expects the web folder to be called 'war'. This is a shared project and it would be really inconvenient to change the name from 'WebRoot' to 'war'. Is there any other way to get hosted mode to stop using the deprecated GWTShell? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Eclipse plugin for Eclipse 3.5 (Galileo)
I agree with Isaac 100%. The attitude was completely inappropriate. If a project is time sensitive then it wasn't wise to take the risk and wait for the next release. When one takes risks one should only blame him/her-self. We should thank google developers for being responsive, for the dialogue that we (GWT users) can have here with them.

Re: Eclipse plugin for Eclipse 3.5 (Galileo)
Just to clarify a few things: 1. I demand absolutely nothing and I have nothing but high regard for the coders at google who develop the gwt framework. 2. I have no project on hold for lack of the plugin. I was simply wanting to test it on Galileo, see how well it works. 3. My earlier comment was in regard to expectations of delivery that have been given. 4. I use the GWT framework, and I also promote it and help others around me use it. 5. Being branded by Mr. Isaac as someone who rudely seats back and yells is utterly offensive to me. I am sure those comments cannot come from someone who has any regard for the comunity of developers that help GWT grow.

To to test your requirement:
final CustomTextBox textBox = new CustomTextBox();
textBox.addDoubleClickHandler(new DoubleClickHandler() {
@Override
public void onDoubleClick(final DoubleClickEvent event) {
textBox.setText();
}
});
Option 2:
Increment a clickCount variable inside a ClickHandler. Start a Timer
on the first click which resets the clickCount after a certain
timeout. If the click count is = 2 on any click then you have a
double click. Obviously this is not as good as Option 1 since you have
to use your own double click timeout which may be different to the
user's operating system setting.
Hope this helps.
Cheers,
Paul.

Re: I18n and special Characters
Set everything to UTF=8 The project (if not the default for Eclipse if that is what you are using).

Running a project against a non-Java server (with JUnit)
We have a nice GWT project that hits our XQuery server but are missing out on many of the features of GWT, and I'm trying to add them in despite our non-standard configuration. The overall situation should be identical to GWT+Ruby or PHP, except that we are using XQuery as the back end language.One item is that I get either "The development shell servlet received a request for 'MyApp.css' in module 'com.foo.app.MyApp.JUnit.gwt.xml' "errors, and/or cross-domain violations when I try to Run JUnit to test a service. Specifically, the files are simply not found when I use a relative URL for the RequestBuilder, and if I hardcode the URL to be the correct server+port I also get cross-domain violations. Our setup is that we use GWT with v 1.6 to push compiled .js into a war directory which also contains XQuery code, and have our non-java server serve up files from that location. Running JUnit (or hosted mode) however seems to lock us into the embedded tomcat that GWT uses. Are there standard workarounds? I'm considering trying to proxy everything with a small Java server that is also running to provide some file processing utilities we need, but am concerned about the performance impact of that approach.Thoughts or pointers would be appreciated.Damon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

[gwt-contrib] Re: Proposal for improving JDO/JPA RPC support
Hi Sami - 1) To track the previous state would seem to require doubling the amount of data sent from server to client, which doesn't seem like a good tradeoff in general. My proposal avoids the need to send extra data by simply allowing everything to be marked as dirty. What are your specific questions about collections and PersistentSet? 2) The only places I can see to store the extra field data are a) on the client or b) in the persistent store. The HTTP session won't work, I think. For example, the server could be behind a load-balancer, so the object would be materialized on server A, sent to the client, and sent back to server B. If the extra data is not sent along with the object, it has to be somewhere that both A and B can access. It can't just live in A's VM heap. My thought is that it would be counterintuitive for GWT RPC to attempt to modify the persistent store, and probably would create problems.

This mecanisms seems to cover all the nominal use cases that we would face regarding the different o/r mapping impl. I would just make a few remarks : 1) When you call all the setXX() methods when the object is sent back to the server, the o/r mapper will assume that those fields have been modified and the dirty state tracking (which is activated before the setXX() call if I well understand) will raise an update operation for all the fields. I think you have to compare bean n-1 field values and bean n field values to call only the setXX() for the modified values. What about collection ? Hibernate provides a PersistentSet that ensure the object state tracking, will you call setXX() for all items of client data ? 2) If you analyze an enhanced entity in the Hibernate land you will see that it contains many coarse-grained information, like a SessionImplementor (it depends on the dynamic proxy factory and impl you have used) - https://www.hibernate.org/hib_docs/v3/api/org/hibernate/proxy/ProxyFactory.html. Serializing those data in a String based representation could be potentially harmful in term of bandwith and payload. Why not providing a way to store this client data info in the HttpSession ?

I'd like to give those of you who are interested in the interaction between RPC and persistence a chance to help me validate the design before moving forward. The idea is to be able to deal with different persistence mechanisms in a way that does not depend too much on the details of their implementations. We assume that the persistence mechanism provides a way for instances to be detached from the object store, serialized, deserialized, and reattached in a well-defined way. Our strategy leverages this capability as follows: 1) User code on the server detaches the object and places it into a state such that serialization is valid 2) GWT detects whether any instance fields are present on the object that were not known to client code 3) GWT performs hybrid serialization: a) GWT uses its regular RPC mechanism for the client-visible fields b) GWT uses Java serialization for any additional server-only instance fields c) GWT encodes the results of step (b) as a String d) GWT prepends the encoded String to the regular RPC data and transmits to the client 4) Client code treats the object in the normal way and does not interact with the data from step (3b) 5) When the object is sent back to the server, the normal RPC mechanism is altered as follows a) the encoded server data is decoded and deserialized into the new object instance b) the client data is populated using setXXX() method invocations rather than by directly setting field values All this is done only for classes that can be send bidirectionally, and which are determined to be (potentially) enhanced. The potential for enhancement is signaled in one of three ways: o The user adds the fully-qualified class name to a 'gwt.enhancedClasses' configuration property o The class is determined to have the JDO @PersistenceCapable annotation with detachable=true o The class is determined to have the JPA @Entity annotation If a class is determined to be potentially enhanced, the list of fields known to the client is added to the '.gwt.rpc' file that contains the RPC whitelist. This list is used by step 2 of the RPC process which compares the set of client- and server-visible fields. Step (5b) is necessary to accommodate mechanisms like that of JDO, where the setter methods are enhanced to provide object state tracking (dirty bits). If we were to set the fields directly,
[gwt-contrib] Re: Proposal for improving JDO/JPA RPC support
Hi Dan, Please correct me if I'm wrong. As I understand your proposal, when entity A get back to the server after being modified by the client, you assume that all fields are dirty if extra data are not present ? If extra data exists, you don't compare extra-data state representation (which would be in fact n-1 fields state) with the actual state of your entity ? In other terms, are extra data only a raw base64 serialization of the previous bean state ? My concern about PersistentCollection is the following - Hibernate ensure that dirty state tracking is handled by a kind of client side collection wrapper. If you remove the PersistentCollection type and its behavior, you lose the ability to track on the client side the elements inserted/removed/modified. When you go back to the server, you can only assume that all the elements of your collection are dirty, which would raise (with Hibernate) a [delete all/insert all] operation instead of a simple update. Transitive persistence and cascading merging are handled by information stored in PersistentCollection (that other would call an Observable Collection). Regarding the second point, I agree with you that storing the extra-data on the client is better to ensure that you are stateless architecture compliant. You will probably get complains coming from people that have a pretty complex object graph to serialize.

The idea is to be able to deal with different persistence mechanisms in a way that does not depend too much on the details of their implementations. We assume that the persistence mechanism provides a way for instances to be detached from the object store, serialized, deserialized, and reattached in a well-defined way. Our strategy leverages this capability as follows: 1) User code on the server detaches the object and places it into a state such that serialization is valid 2) GWT detects whether any instance fields are present on the object that were not known to client code 3) GWT performs hybrid serialization: a) GWT uses its regular RPC mechanism for the client-visible fields b) GWT uses Java serialization for any additional

I'm about to start the review thread for the core Layout class and supporting code (and post an initial design doc at the same time). It is a low-level class that works directly with elements, and is meant primarily to be used by higher-level widgets. It, along with the design doc, should give you an idea of how it all works, and if you like you can start using it directly. I plan on following up with individual widget reviews soon thereafter, and the Dock/Split widget will be among the first. --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
[gwt-contrib] TextArea getCursorPos fix for IE in pyjamas, is it the right approach?
folks, hi, as you know, pyjamas tracks GWT fairly closely, with the UI widget API being near-identical to that of GWT, and even to the point where i wrote a java2py.py script which converts GWT java code [mostly] to python, to make the process of porting GWT widgets over to python that much easier. we even copy over the platform overrides with the Javascript sections, wholesale. on very rare occasions, we encounter bugs before you do :) i was wondering therefore if you've encountered this: http://code.google.com/p/pyjamas/issues/detail?id=205 your thoughts appreciated. l. --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
[gwt-contrib] Re: Proposal for improving JDO/JPA RPC support
At least in JDO, the extra data is essentially a couple of bit sets. It doesn't contain any additional copies of field values. I'm not sure what would happen with collections -- if one were used as a field value, we would call a setter and hand it entire collection, which I suppose Hibernate would have to treat as an entirely new object. Trying to track the individual changes on the client seems like a much harder problem than what I am proposing at the moment. Dan On Mon, Jul 27, 2009 at 4:50 PM, Sami Jaber sami.ja...@gmail.com wrote: Hi Dan, Please correct me if I'm wrong. As I understand your proposal, when entity A get back to the server after being modified by the client, you assume that all fields are dirty if extra data are not present ? If extra data exists, you don't compare extra-data state representation (which would be in fact n-1 fields state) with the actual state of your entity ? In other terms, are extra data only a raw base64 serialization of the previous bean state ? My concern about PersistentCollection is the following - Hibernate ensure that dirty state tracking is handled by a kind of client side collection wrapper. If you remove the PersistentCollection type and its behavior, you lose the ability to track on the client side the elements inserted/removed/modified. When you go back to the server, you can only assume that all the elements of your collection are dirty, which would raise (with Hibernate) a [delete all/insert all] operation instead of a simple update. Transitive persistence and cascading merging are handled by information stored in PersistentCollection (that other would call an Observable Collection). Regarding the second point, I agree with you that storing the extra-data on the client is better to ensure that you are stateless architecture compliant. You will probably get complains coming from people that have a pretty complex object graph to serialize.

My proposal avoids the need to send extra data by simply allowing everything to be marked as dirty. What are your specific questions about collections and PersistentSet? 2) The only places I can see to store the extra field data are a) on the client or b) in the persistent store. The HTTP session won't work, I think. For example, the server could be behind a load-balancer, so the object would be materialized on server A, sent to the client, and sent back to server B. If the extra data is not sent along with the object, it has to be somewhere that both A and B can access. It can't just live in A's VM heap. My thought is that it would be counterintuitive for GWT RPC to attempt to modify the persistent store, and probably would create problems.

[gwt-contrib] Allow new strings to be created in the JS AST
Reviewers: Lex, scottb, Message: Review requested. @Lex, the implementation follows our IM discussion pretty much as discussed. Description: This patch changes the way code-splitting and string interning is performed on the JS AST to allow new strings to be introduced by JsVisitors (such as JsStackEmulator). Changes: - Remove string tracking from CodeSplitter - JsStringInterner is made aware of code splitting and is run after CodeSplitter - JProgram exposes a new API to indicate fragment load order JProgram.lastFragmentLoadingBefore should be extracted into an interface which JsStringInterner depends on. Is is called LoadOrderOracle?

[gwt-contrib] Re: Allow new strings to be created in the JS AST
Bob, Woohoo! I assume this patch general purpose and would allow any of the Js optimization passes to introduce new string literals? I ask because I ran into the problem a few months ago when I wanted to introduce some extra stuff into JsStaticEval for mirroring the Simplifier in the Java AST (concating strings) but at the time, there was a very scary warning on the JsProgram.getStringLiteral :), which appears gone now, so I assume all restrictions are gone? -Ray On Mon, Jul 27, 2009 at 3:56 PM, b...@google.com wrote: Reviewers: Lex, scottb, Message: Review requested. @Lex, the implementation follows our IM discussion pretty much as discussed.

[gwt-contrib] Locking Columns in PagingScrollTable
I'm about to embark on coming up with a way to lock 1 or more of the left-most columns. E.g., the locked columns will not scroll horizontally as the other columns are scrolled. I've googled around, and not found any other work towards this, so I'm hoping it's not impossible. Currently, I'm using the PagingScrollTable... My first thought is that I would create a wrapper that would internally separate the TableModel into two, and create two separate PagingScrollTable instances, smushed side-by-side. However, if I do this, one thing I really am unsure of is how to keep the height of each row in sync? I appreciate any hints, tips, and/or tricks! jay --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
