Re: how to avoid instanceof checks in ActivityMapper ? is DoubleDispatch used in Expenses sample ?
I'm sorry but, what's the problem actually? theoretical purity?

Re: Adding event handler to UiBinder
Don't use an Image widget, but an element that you'll apply the ImageResource to (or, even better, use a @sprite in a CssResource if you can): create an AbstractImagePrototype from your ImageResource, then use either one of getHTML or createElement (if you don't plan on supporting IE6 –and I really mean IE6, not the whole ie6 permutation, i.e. this will work OK in IE7 and IE8 in compatibility view–, then you can even use applyTo, by cast()ing your element to ImagePrototypeElement) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT MVP Activities and Places
Is there any existing sample-projects which use this structure, with DI(gin/guice) ? On 3 Des 2010, 14:08, Brian Reilly brian.irei...@gmail.com wrote: That's the exact use case for FilteredActivityMapper and CachingActivityMapper (and how they're used AFAICT in scaffold applications generated by String Roo for the master activities). Thanks for the confirmation, Thomas. I felt like it was a bit cumbersome to use, but it makes more sense as a consistent way to get that behavior in generated code (which is unfortunate, but it is what it is). what about situations where a display region is master in some cases (requiring to be cached), and detail in other cases ? for example, when we have West, Center, and East Regions, Center region can act as Detail for West Region in some use cases, but in other use cases, be used as Master for East Region. I can think of two approaches, depending on the specificity of the places. 1. Use an activity mapper for the center region but not the east region. This would be appropriate if the center region shows the item of interest and the east region contains some contextual detail that isn't worthy of being encoded into a place. 2. Have both the center and east regions react to the same place where, unlike option 1, the place contains enough context for both regions. The east region would use that extra detail to display something specific about the item of interest while the center region can ignore it if it doesn't affect what's displayed. I'm sure there are more ways to approach it. Just keep in mind that activity mappers are for mapping places to activities. Once you decide how granular you want your places to be, that will help determine the best use of activity mappers. what happens if we use CachingActivityMapper for ALL of our ActivityMappers ? would there be a performance problem, what are the implications, benefits or drawbacks ? CachingActivityMapper caches the last activity it returned, to be re-used if we see the same place twice (http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/g...). If your concern is memory, there should be little to no overhead when using a CachingActivityMapper. As for performance, the goal of CachingActivityMapper is to avoid initializing a new activity (and potentially fetching data from the server, doing client-side processing, etc.) when the current activity already represents the requested place. I can't think of any downside to using CachingActivityMapper... as long as the wrapped activity mapper and the places it uses are implemented as advised (be sure to properly implement equals() and hashCode() for your places). -Brian -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Assign handler to UiHandler
Hi,
sorry I could not find this anywhere. I know I can add handler like this:
@UiHandler(submit)
void onClickCreate(final ClickEvent e) {
if (check())
create();
else
Window.alert(messages.wrongConditions());
}
but how would I mimic this using UiBinder (UpperCaser class implements
BlurHandler):
lastName.addBlurHandler(new UpperCaser());

How to write file with GWT?
Hello to all ...
I have to write an XML doc with GWT. I discovered that you can not do
client-side but it can be done with server-side.
So I setup the synchronous and asynchronous client-side:
package com.example.foobar.client ;
import com.google.gwt.user.client.rpc.RemoteService;
public interface extends RPCInterface RemoteService {
testRPC public String (String message);
}
--
-
package com.example.foobar.client ;
import com.google.gwt.user.client.rpc.AsyncCallback;
public interface RPCInterfaceAsync {
testRPC void (String message, AsyncCallback callback String);
}
--
---
while on the server-side I did:
import java.io.BufferedWriter;
import java.io.DataOutputStream;
import java.io.FileOutputStream;
import java.io.FileWriter;
import java.io.IOException;
import java.text.DateFormat;
import java.util.Date;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
import com.example.foobar.client.RPCInterface;
public class extends RPCImpl RemoteServiceServlet implements
RPCInterface {
private static final long serialVersionUID = 1L;
testRPC public String (String message)
{
Date now = new Date ();
Dtm DateFormat.getTimeInstance String = (DateFormat.MEDIUM.) Format
(now);
try {
BufferedWriter out = new BufferedWriter (new FileWriter (test.txt));
out.write (message);
out.close ();
} Catch (IOException e) {
}
return This is my message + message;
}
}
--
-- -
I have not forgotten anything in the matter, because before you use
the class FileWriter and BufferedWriter the program run smoothly.
I have these errors:
ERROR] javax.servlet.ServletContext log: Exception while dispatching

EnterButton
I have a couple of places where I want the user to be able to hit
enter, and have a button clicked. So I created the class EnterButton,
which has all the default constructors, and the following bit of code:
public void onKeyPress (KeyPressEvent event)
{
int keyCode = event.getNativeEvent ().getKeyCode
();
if (keyCode == KeyCodes.KEY_ENTER)
click ();
}
Is there a reason why some such class isn't part of GWT already? Is
there something in this code that will turn around and bite me in the
tush?

Re: How to write file with GWT?
The stack trace says it all...
com.example.foobar.client.RPCInterface.testRPC (java.lang.String)'
Threw an unexpected exception: java. lang.NoClassDefFoundError:
java.io.FileWriter is a restricted class. Please see the Google App

You appear to have your test module in the com.example.foobar.client package.

This means that the GWT compiler will compile that module and it looks to me like that contains a
reference to java.io.FileWriter - as the stack trace message says, the developer's guide will
explain to you exactly what the problem is but the 'executive summary' is that java.io.FileWriter
can't be used in GWT 'client' code because it can't be compiled to Javascript.
The rule in GWT is:
1. things that will only be run as javascript on the client should be in the your.module.client.*
packages
2. things that will only be run on the server should be in the
your.module.server.* packages
3. things that will be shared by the client code should be in the your.module.shared.* packages -
IMHO these should be kept to a minimum.
You must make sure that you have both client and shared in the

Re: Real-time app: best approach
Which grid/table would you recommend? I used GXT grid and the new CellTable, but they are too slow or not able of rendering its content dynamically while scrolling. How would you send that data to the client, what is the fastest way? I make a String for each row, send it to the client over RPC and parse it back, but that's not the fastest way I assume. @Jeff: The 400MB I mentioned are for the client side only. @Brian: paging is not in the requirement and therefore not an option.

event plumbing
Hi, please help me to debug (or even better - to tap) events to PopupPanel/ MenuBar. I'm trying to create context menu over OpenLayers map. Composite which contains map sinks mouse events and I can see that those events are processed. When I'm creating PopupPanel containing MenuBar, PopupPanel shows in place I expect after Event.ONCONTEXTMENU event and it correctly responses to mouse clicks and closes properly. So far everything is ok. My problem is - it seems that my MenuBar somehow interferes with map sitting beneath it - it doesn't respond to mouse move events (doesn't highlight mouse over MenuItem) and clicking on it works as it was click outside PopupPanel - MenuItem command is not executed. Overriding PopupPanel, MenuBar and adding explicit sinkEvent of required mouse events doesn't help. During context menu handling I'm not interested in map. How could I take over mouse control and direct necessary events to my MenuBar? Thanks, Grazvydas -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Generated Maven pom.xml does not add GWT project natures
Hi GWT gurus, I'm generating an Eclipse project using webAppCreator.

Handling clicks on CellWidgets
Hi, Happy new year to all! I have some questions regarding cellwidgets. In the showcase http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellSampler when clicking the cell which contains the button, it reacts not only when pressing the button but also when clicking inside the cell but outside the button. First Question, can i avoid this behavior and only reacting to the button press in a cell? Inspecting the code for this example and the sample from CellList i see the following: From the CellList example, each cell is a div with a single onclick. div onclick= __idx=0 class=GEGGSC0BI style=outline:none;tabletbodytr ... /tr/tbody/table/ div From the CellSampler (which uses a cellTable) the onclick is not in each cell but in each row. tr onclick= class=GEGGSC0BEDtd class=GEGGSC0BDC GEGGSC0BFD GEGGSC0BGCdiv style=outline:none;/div/td/tr I tried to use a composite cell with two buttons in a celllist but as there is only one handler per cell, clicking on any of the two buttons (and also outside the buttons but inside the cell) reacts with the same handler. I can't distinguish them. Question 2. How can I distinguish clicks inside a cell when using a cell list. Question 3 Am I forced to use celltable with different cells for each column. Question 4 How do you managed to distinguish cellclicks if there is only one handler per row in a celltable? I know the questions are not very concise, sorry.

Re: How to write file with GWT?
Hi Sebe
As I understand it, you want to be able to upload a file from the client and
save it on the server.
One important point -
You CANNOT read and write files in the local (that is, client) computer's general filing system
using javascript in the browser. You can only upload a file to the server, save it on the server's
filing system and then download it to the client again. If you want to do anything else you simply
can't, it would be a huge security loophole and there's enough anarchy in the web already!
I'm not very familiar with GAE but a quick scan of the docs seems to indicate that you will have to
use the BlobstoreService and upload your files to the BlobStore. One thing you *can't* seem to do is
modify the contents of the BlobStore from within the server application. It is a restriction of GAE
that you can't save files to the local filing system - if you host your own server (*not* GAE) you
can do this.
If all you want to do is to upload the file and then serve it back to your user
that seems easy.
You can also read the blob data, with the 'fetchData' method, so you if it is XML you can read it
and return (parsed if necessary) to your client maybe using some kind of XHR request like in the
code you posted.
To upload the files in your GWT app you will need to use a FileUpload widget - the example in the
javadocs is pretty comprehensive.
As I've never used GAE I can't be of any more help at this point, but others on the list may have
more relevant experience.

Re: Having multiple semi-autonomous .html pages vs single page with multiple Places ?
One implication that you'll have is the possible increase of compilation units in your applications. Since each of the host pages would show something different, you'd have one entry point for each. Since you don't want to download and start all of the entry points when you're only using one, you'll want them in separate modules. This will slow down GWT compilation because any code shared among the modules (including GWT itself and the JRE emulation layer) will be recompiled for each module. For a new project, I'm not sure what you would gain be keeping these separate, other than having separate .html locations for each feature (which is a purely aesthetic decision as you can achieve persistent locations for each feature using GWT's history support, especially places in GWT 2.1). I faced a similar problem when trying to integrate GWT into a legacy application. I didn't want to replace the entire application frame (yet) but wanted to be able to implement certain pages using GWT. After manually implementing a solution involving a single dispatching entry point and a javascript variable token, I came across gwt-multipage (http://gwtmultipage.org/) which did something similar using a URL pattern. I contributed the javascript token switching logic to that project and am using it now. If you really need separate pages, that might be helpful for you. -Brian On Sat, Jan 1, 2011 at 8:29 PM, zixzigma zixzi...@gmail.com wrote: Hello Everyone, normally GWT apps are consisted of only one HTML page. this html page loads one or more scripts.

Request Builder and cross domain requests
I am trying to use RequestBuilder to access an xml document that is
available on the same server as my GWT 2.1 application but in a
different servlet container. Thus my GWT application is accessed via
http://localhost:8084/sdv and the xml document is accessed via
localhost:8086:/geoserver/rest/...
The code I am using is shown below.
RequestBuilder builder = new RequestBuilder( RequestBuilder.GET,
getRestUrl(layer));
try
{
Request request = builder.sendRequest(null, new
RequestCallback()
{
public void onError(Request request, Throwable exception)
{
}
public void onResponseReceived(Request request, Response
response)
{
}
});
}
catch (RequestException e)
{
}
Is it that the domain is bboth the server and port, not just the
server.

SelectionCell is displaying empty combo box
Hi,
I have a cellTable and am displaying combox in one of the columns.
I use SelectionCell for the same but my problem is that the combobox is
displayed in all rows but all are empty, they dont show any values there.
Code is as follows:
final ListString picUps = new ArrayListString();
// Adding values to picUps list
SelectionCell picUpPointCell = new
SelectionCell(picUps);
ColumnIBusObjectRpc, String pickUpCol = new ColumnIBusObjectRpc,
String(picUpPointCell) {
@Override
public String getValue(IBusObjectRpc object) {
if(object instanceof TktvalaTripDTO) {
return ((TktvalaTripDTO)object).getPickupPoint().get(0).getName();
}else if(object instanceof TktgooseBusDTO) {
return ((TktgooseBusDTO)object).getPickupPoints().get(0).getDesc();
}
return null;
}
};
table.addColumn(pickUpCol, Pic ups);
I make sure that the proper values are returned from getValue().
Can somebody find out what i am doing wrong.
Thanlks
Deepak

Asyncronous calls in RCP behaves wierd.
Hello, I'm doing a project where in the interface shows a listBox that
includes the names of some books, the thing is that you must choose
one and you will look wether in pdf or txt. My problem is that when
changing the listbox, itll show the just last book you chose, rather
the current one.
heres the program so far.
http://kido180020783.appspot.com/
Here's the part of the code that presents the problem.
setCurrentBook(bookList.getItemText(bookList.getSelectedIndex()));
if (pdfFlag) {
if (!txtFlag) {
pdfBook.setSize(booksPanelWidth,
booksPanelHeight);
} else {
booksPanelWidth =
String.valueOf(BOOKS_PANEL_WIDTH / 2);
pdfBook.setSize(booksPanelWidth,
booksPanelHeight);
txtBook.setSize(booksPanelWidth,
booksPanelHeight);
}
pdfBook.setUrl(pdf/ + currentBook.getUriPath() +
.pdf);
} else {
..
//This method is being called AFTER the line pdfBook.setUrl(pdf/ +
currentBook.getUriPath() + .pdf); wich is weird!!.
public void setCurrentBook(String bookName) {
AsyncCallbackBook callback = new AsyncCallbackBook() {
public void onFailure(Throwable caught) {
throw new UnsupportedOperationException(Not supported
yet.);
}
public void onSuccess(Book result) {
currentBook = result;
}
};
bookServicesHolder.loadBookByName(bookName, callback);
}
I dont want the method to be Asyncronous, please I really need some
help.

empty ghost place token getting created
Hi
In my application, I'm using the MVP pattern with activities and
places. I have a situation where:
(1) I explicitely call: placeController.goto(new SomePlace());
(2) The appropriate SomePlaceActivity's start() gets called via event
management as expected.
(3) This method creates gets a SomePlaceView, and swaps it into the UI
(4) An appropriate history event happens and
http://mylocalenvironment#SomePlace:someplace
appears briefly on my browser's nav bar.
Then it gets weird.
(5) A new empty String token gets created somehow.
(6) It goes through the history management process, causing the
defaultPlace to be created
(7) The start() method on DefaultPlaceActivity() gets called
(8) The app navigates away from SomePlace to DefaultPlace
which makes me sad and very confused. I cannot figure out how that
empty token gets created and the event handling mechanism gets invoked
the second time. The code for this is, of course, spread over many
files so its difficult to provide all the relevant code, but I've
included much of what I think could be useful here. I'm hoping that
people have seen this happen before and can point me to a typical
cause.
// from my ActivityMapper
public Activity getActivity(Place place) {
if (place instanceof LoginPlace)
return new LoginPresenter((LoginPlace) place,
factory);
else if (place instanceof SomePlace )
return new SomePlaceActivity((SomePlace) place,
factory);
else if (place instanceof ForgotPasswordPlace )
return new
ForgotPasswordPresenter((ForgotPasswordPlace) place, factory);
return null;
}
// from SomePlace
public class SomePlace extends Place {
private final String name = somePlace;
public SomePlace() { }
public String getName() { return name;}
public static class Tokenizer implements PlaceTokenizerSomePlace

{
return place.getName();
}

Re: how to avoid instanceof checks in ActivityMapper ? is DoubleDispatch used in Expenses sample ?
are you suggesting this is nothing to worry about ? in the case of Expenses app, there are only three entities: Expenses, Reports, Employees (and number of places and fine-grained activities mapper, is relative to the number of entities) however, in a larger app , there might be 50 entities. and when using 4-5 ActivityMappers (for different display regions), it will get difficult to manage. #1 - One approach is checking all our 50 entities(or places) in one giant if/else block. (50 if/else statement) #2- However, I believe we can group together our fine-grained activities-mapper, by using a base class for each group, and delegating the instance of checks, to a more specific activities mapper. this is better than using one giant if/else in ActivityMapper, but somehow these selections gets scattered. My Concern is this: I have read that frequent usage of instance of is a sign of code smell.[*] and also have read that if we have to resort to conditional instanceof checks, it is better to keep it in one place for the smell not getting spread ! the approach #2, delegating the instanceof checks to a more specific mapper, will result in the code smell to spread. and code inspection tools also flag these instanceof, it gives the impression of poor application design. this is what I'm very worried about : ( [*]Java quality assurance by detecting code smells http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.80.2066rep=rep1type=pdf -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Layout three GWT panels Horizontally
Just a question before trying this method: you don't think using DockLayoutPanel (which uses absolute positioning) will not allow my Editor Panel to resize automatically to the height of its children widgets? I was encountering this problem with first code using DockLayoutPanel ; so you suggest only use DockLayoutPanel as the top higher Panel to hold all other children widgets and that the children widgets should not use DockLayoutPanel ; is that correct?

Re: Upgrade to GWT 2.1.1
Aldo,
If this is a Roo-generated app, you'll need to wait to until Roo 1.1.1 is
released to upgrade to GWT 2.1.1. For now Roo-generated apps are only
compatible with GWT 2.1.

Re: Layout three GWT panels Horizontally
No Sorry this doesn't work! as i explained the DockLayoutPanel is not automatically resized to fit its children height.it uses absolute positioning (i explained this issue in my post). this gives me a weired Panel displaying nothing! as i guess its children height should be set. but i need the Editor to resize automatically into its children height. any other Idea?

Re: Asyncronous calls in RCP behaves wierd.
If I understand your code correctly, its actually doing exactly what you've
asked it to do.
You are calling a method called 'setCurrentBook(..))' which doesn't seem to
do anything very much.
You are then defining a callback 'public void setCurrentBook(String bookname)'
blah...
You are then *invoking* the call back
bookServicesHolder.loadBookByName(bookName, callback);
Your call back sets a variable called 'currentBook' and I cannot see what you intend this to do from
the code provided, but, as written, its not going to do anything very much. If if is a global
variable then you will never get the result you require.
You need to carefully re-read the section in the GWT docs about Asynchronous calls. If you are using
GWT you *MUST* use and fully understand asynchronous RPC - that's what Ajax is all about.
It *should* go something like this.
* Define an RPC callback for a particular service typically by using an
anonymous inner class.
* Invoke the call back specifying the data object (book) you want to read
* On the successful asynchronous return, update the UI, by calling the update method from within the
callback onSuccess method. There are many, many examples out there.
In short, don't update the UI until the callback returns.
If you don't want to make these calls asynchronous, then convert your program to a more
servlet-centric approach. There are a (large) number of other web frameworks which will do this for
you. GWT is all about Ajax and RPC.

Re: how to avoid instanceof checks in ActivityMapper ? is DoubleDispatch used in Expenses sample ?
My app has a Place for every EntityProxy type. BasePlace has getProxyType() method that is called in MyActivityMapper.getActivity(place). Based on the proxy type returned, getActivity() method looks up an activity factory and calls factory.createActivity(place, config) All I have to do is to create an factory for every activity and configure the lookup table. If I forget to create a factory for a new activity, an assert will warn me about that. This might not be the best approach (may be there is a way to replace my factories with Gin, but I haven't investigated this yet), but I don't have any instaceof's in the ActivityMapper. If someone uses other approaches, please share, it would be very informative.

First Question, can i avoid this behavior and only reacting to the button press in a cell?

I can't distinguish them. Question 2. How can I distinguish clicks inside a cell when using a cell list. Try using ActionCell instead of ButtonCell Question 3 Am I forced to use celltable with different cells for each column. You can use the same Cell for several columns. If you want columns though, you have to use CellTable, of make your own Cell widget (not trivial) Question 4 How do you managed to distinguish cellclicks if there is only one handler per row in a celltable? Cell widgets use event delegation, they register a single event listener but then dispatch accordingly, depending on the exact element targetted by the event (i.e. FieldUpdater for a given Column, onBrowserEvent and ValueUpdater for a given Cell) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: empty ghost place token getting created
another clue?
It seems to have something to do with the Tokenizers. If I comment
out these places from the @WithTokenizers{} section of my
PlaceHistoryMapper definition as shown at the bottom below, the
navigation works correctly (in the sense that the correct page is
loaded and navigation stops) but there are no bookmarkable urls and
the back button does not work.
What I'm looking for here is pretty simple: For the places defined so
far, I want a url that looks like: http://myDomainEtc#SomePlace with
no more specific data needed.
I saw in the documentation: Many places in the app might not save any
state to the URL, so they could just extend a BasicPlace that declares
a PlaceTokenizer that returns a null token. I tried that, with the
same result as the original implementation. The URL now looks like
http://myDomainEtc#SomePlace:null, but as long as @WithTokenizers{}
includes my SomePlace class, the URL is replaced immediately with a
plain one and the browser loads the defaultPlace.

The whole point of putting it in a blobstore is to avoid having lots of complicated code on the client to parse and process the data. The server processes it, caches it, and makes it available via a URN-based keying system. One possible option is to binhex it, I suppose, but that isn't very attractive, requiring an extra processing step on the client. I think I'll just stick to using Amazon EC2 for my web services!

Re: how to avoid instanceof checks in ActivityMapper ? is DoubleDispatch used in Expenses sample ?
thank you for your suggestion. I was thinking of a similar approach, but couldn't come up with a way to populate the lookup table (initialize it for the first time with data). could you please explain how you register activities/places in the lookup table, so that they are available at run-time ? and your comment: My app has a Place for every EntityProxy type. how do you deal with composite entities ? for example, lets say part of our app deals with Projects/Tasks/Issues we have a number of projects, each with a list of tasks and their own list of issues. we would use ProjectProxy and TaskProxy and IssueProxy respectively. and apart from these related places/proxies/activities, lets say another section of our app deals with Account, Payment, BillingHistory, therefore we would need corresponding places/proxies/activities given the scenario above: #1 do you treat each of the entities in isolation, to model their Places/Activities or #2 you group them in a hierarchy for example, ProjectPlace/TaskPlace/IssuePlace can have AbstractProjectPlace base class, or an interface ProjectActivities, TaskActivities, IssueActivities can have an AbstractProjectActivities base class. therefore we are forming a hierarchy, that is different than that of Account, Payment, Billing History, for these three, we use AbstractAccountAcitivites and AbstractAccountPlace base class for Places and Activities. this is one approach, another approach is treating all of them in isolation, act as if Task/Place/Issue have no relationship with eachother, and treat them no differently than Account/Payment/Billing History despite the fact they can be grouped together in their workspace dealing with usecases specific to their hierarchy. what is the best way to deal with scenario above in GWT MVP ? should Activities/Places mimic structure of entity they are related to ? (forming parallel object hierarchies ? for place/activity/proxy ) Thank You -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Is it possible to consturct CellTree form database via rpc
Thank you Y2i, Your messages are greatly help to me But there is an another problem stuck in... updataRowCount() and updataRowData should work with hasData, but cellTree doesnt implement it, so my requestion is, as to cellTree, how do both functions above work?

Re: [gwt-contrib] Stack overflow problem in HashMap.hashCode() and possible fix
mP, This is not a bug in the client, because this is exactly what the client in my case is trying to represent (a recursive graph of maps). It's not a bug to represent that structure. However since regular Java does not support this (i just checked), I agree that GWT should emulate Java's behavior. In my case I'll use the wrapper type I described above, and you're right - I'll have to override equals too. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
Re: [gwt-contrib] Stack overflow problem in HashMap.hashCode() and possible fix
Have you seen this note in the javadoc for java.lang.Map: Note: great care must be exercised if mutable objects are used as map keys. The behavior of a map is not specified if the value of an object is changed in a manner that affects equals comparisons while the object is a key in the map. A special case of this prohibition is that it is not permissible for a map to contain itself as a key. While it is permissible for a map to contain itself as a value, extreme caution is advised: the equals and hashCode methods are no longer well defined on such a map. – http://download.oracle.com/javase/6/docs/api/java/util/Map.html Instead of using a Map directly, maybe you should use an wrapper object that implements equals() and hashCode() independently of the content of the Map. Or, instead of using the Map itself as the key, use a sentinel object (e.g. public static final Object THIS_MAP = new Object(); ) (that being said, I'm having a hard time figuring out what could represent a Map that contains itself as a *key*) -- http://groups.google.com/group/Google-Web-Toolkit-Contributors

Thanks for the link, Notice however that I'm not using the map as a key in itself, but as a value in itself, and as a key in another unrelated map.

[gwt-contrib] Re: Stack overflow problem in HashMap.hashCode() and possible fix
Here's my complete wrapper. It's rather simplistic and could probably use
some optimization in .equals, but I didn't try an awful lot.
Comments welcome.
/**
* A wrapper of HashMap that support recursion in values (can contain itself
as a value) and still calculate
* hashCode and equals correctly.
*/
public class FixedHashMapK,V extends HashMapK,V {
protected boolean _inHashCode = false;
protected HashSetFixedHashMap?,? _inEqualsWith = new
HashSetFixedHashMap?,?();
@Override
public int hashCode() {
int result = 0;
if (_inHashCode ) { return result; }
_inHashCode = true;
result = super.hashCode();
_inHashCode = false;
return result;
}
/**
* Equals needs to fix the case of comparing two recursive maps. The
rest is handled by the default implementation.
*/
@Override
public boolean equals(Object other) {
if (this == other) {
return true;
}
if (null == other) {
return false;
}
if (!(other instanceof HashMap)) {
return false;
}
if (!(other instanceof FixedHashMap)) {
// We assume other is a non-recursive map,
// and the default .equals doesn't recurse infinitely
return super.equals(other);
}
// It may be a recursive map.
FixedHashMap?, ? savedOther = (FixedHashMap?, ?) other;
if (this._inEqualsWith.contains(savedOther)) {
// We are already comparing ourselves with this object!
// Return 'true' because the final result will be the
conjunction ('and')
// of this result and all the other entries. If all the other
entries are equal,
// we can say the maps are equal.
return true;
}
this._inEqualsWith.add(savedOther);
boolean res = super.equals(other);
this._inEqualsWith.remove(savedOther);
return res;
}
}

[gwt-contrib] Re: Stack overflow problem in HashMap.hashCode() and possible fix
For completeness here's a tester. (it passes on the above code)
public static void main(String[] args) {
System.out.println(Run this with vm arg: -ea);
System.out.println(Running test...);
FixedHashMapString,Object recMap1 = new FixedHashMapString,
Object();
recMap1.put(me, recMap1);
FixedHashMapString,Object recMap2 = new FixedHashMapString,
Object();
recMap2.put(me, recMap2);
HashMapObject,Object containerMap = new HashMapObject,
Object();
containerMap.put(recMap1, null); // causes a stack overflow
if recMap1 is a regular HashMap with recursion
containerMap.put(recMap2, null);
System.out.println(assertions...);
assert recMap1.equals(recMap1);
assert false == containerMap.equals(recMap1);
assert false == recMap1.equals(containerMap);
assert containerMap.equals(containerMap);
assert recMap1.equals(recMap2);
assert containerMap.size() == 1;
System.out.println(containerMap.toString());
System.out.println(Done);

You're subclassing HashMap, not wrapping a Map.
But I
don't see how a sentinel would help me in my real use case of a
complex graph of circular references between maps, since it will be
hard to keep track of which sentinel represents which map.
yes, sorry I misread your initial 4-lines repro case.
So , I think you'd to use a wrapper object that implements equals and
hashCode independently of the content of the wrapped map; something like:
// do not implement Map, as it would break the contract for Map.hashCode and
Map.equals
class WrapperK, V {
private final MapK, V map;
public Wrapper(MapK,V map) {
this.map = map;
}
public final MapK, V get() {
return map;
}
@Overrides
public boolean equals(Object obj) {
if (obj == this) {
return true;
}
if (obj instanceof Wrapper) {
// use identity comparison: 2 wrappers are equal if they wrap the very
same map, independently of its content
return map == ((Wrapper) obj).map;
}
return false;
}
@Overrides
public int hashCode() {
// not the best for performances, but at least does not violates the
Object.hashCode/equals contract
return 31;
}
}
Best would probably be to use a subclass of Map that keeps a reference to
the key object so as to maintain a 1:1 bidirectional relationship between
maps and their keys (and that way, you don't even have to implement the
hashCode and equals methods, the default implementations are sufficient):
class MapWithKeyK, V extends HashMapK, V {
public final class KeyK, V {
public MapWithKeyK, V getMap() {
return MapWithKey.this;
}
}
private final KeyK, V key = new KeyK, V();
public final KeyK, V getKey() { return key; }
}
Then, instead of testMap2.put(testMap, null), you'd use
testMap2.put(testMap.getKey(),
null);
