Serialization Policy for a HashMap extension
I'm dealing with recently merged code from other projects that broke my GWT code. Due to some optimization efforts there was a class introduced that extended HashMap. Lets call it HashMapExtension. Even though HashMapExtension extends HashMap it broke the serialization policy of GWT. There is nothing in HashMapExtension that is not serializable. Is there a way to safely add classes to the serialization policy or could this potentially be a bug in GWT. I'd be happy to call it a feature request if that helps. Just looking for clarification.

LayoutPanel with UIBinder
Is there a way to set a component horizontal position in a layoutpanel with uibinder? By default the position is stretch but I would like to set it to begin like this: g:LayoutPanel width=450px height=390px g:layer top=5px left=7px right=5px horizontalPosition=BEGIN g:Button text=Open/ /g:layer /g:LayoutPanel Of course the layoupanel parser does not handle horizontalPosition attribute.

Problem with RequestFactory and two tier
Hi guys, I spent some time trying to undestand why this piece of code (that
I copied from the DynaTableRF) was not working for me:
final RequestContext context = driver.flush();
context.fire(new ReceiverVoid() {
@Override
public void onSuccess(Void response) {
// do something
}
});
No errors but the values modified on the proxy were not saved into the
entity.
I saw that this method of the locator was called:
@Override
public MyEntity find(Class? extends MyEntity clazz, String id) {
and that the correct entity is returned, but anything is modified.
The fact is that the returned entity is updated with the new values from
the SimpleRequestProcessor but at that time the session is closed and the
entity is detached. This work on the DynaTableRF that use a filter that span
the session for the duration of the overall request (OpenSessionInView) but
doesn't work for me, I call EJB 3.0 methods and everything returned to the
servlet tier is detached from the original session.
I solved this problem with a custom update method in my RequestContext, but
I guess if I'm missing something in the understanding of the RequestFactory
world.
Anyone with some advice ??
Thank you.

Re: Problem with RequestFactory and two tier
RequestFactory works like this: 1. for each modified proxy: 1. find by ID or create domain object 2. call setters on the domain object (if a value is a reference to another entity, it will be looked up by ID *again*, this means you must have some kind of session cache for the lifetime of the request) 2. call methods, passing the entities retrieved/created at step 1.1 3. call getId/getVersion on the entity proxies (sent and returned) to tell the client which EntityProxyChange events it should fire 4. call getters to send values back to the client (well, maybe steps 3 and 4 are swapped, I don't remember).

It means you have to provide some kind of session cache if your data access layer doesn't have it; a ThreadLocalMapI,T in your LocatorT,I should be enough. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

The fact that it has a magic number in it (6) is just plain wrong, and
I can not for the life of me remember why that number is there.
rightSize needs to be called when laying out a form, just to get started.
Again this can be done better. It is also possible that somewhere
along the line the need for getScrollHeight has gone, but I have not
been following the API closely enough to see.
To get the full Notes function, one would also need to set the width of
the area. This only sets the height. But that is for another day.

Stack Layout Panel - strange layout problem after switching tabs!
Hello, I have a StackLayoutPanel, where the content panels are DockLayoutPanels. One of these panels contains a ScrollPanel, which contains a FlexTable. So the hierarchy is as follows: StackLayoutPanel - DockLayoutPanel - ScrollPanel - FlexTable (in center) However, sometimes the FlexTable is misplaced, right after selecting the tab: https://picasaweb.google.com/104334857964624808900/GWT#5575015619744351906 This happens only when there is another tab selected first and one switches to this one. (and only in IE, not in FF) I already found that it's the ScrollPanel that is not laid out correctly, but I don't know why. I always thought that the center widgets of a DockLayoutPanel are always stretched... I do not expect a final solution, but I would be glad if I knew where to begin? Could someone point me into a good direction? Thank you Magnus -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

RequestFactory and ValueProxy with Role-base Security
In our company, we're using an EJB backend for Webservices and GWT-client. The Service Layer is protected by Role-based Security. I cannot see any way to use EntityProxies from GWT to access the service layer, *it is impossible to apply the Role-based Security to a generic EntityLocator Service* (the same Entity might be called from two totally different UseCases). Correct me if I'm wrong: but there is no way to use EntityProxies, I therefore must use ValueProxies with RequestFactory. I am aware, that when using ValueProxies, I have to manually merge Entites into the JPA Persistence Context, first needing to lookup the entity by ID and checking the version for Optimistic Lock problems and also checking the relationships to be merged in (which i would like to avoid using EntityProxies...) *a) First problem: need to edit ValueProxy when updating* I defined a ValueProxy that has a @ProxyForName Annotation poining to an Entity. When I want to update an entity with the ValueProxy, I first need to edit() the ValueProxy on the GWT Client. Otherwise, in the RequestFactoryServlet, all attributes of the entity are null an I run into various Exceptions on the backend. To me, this looks kind of strange first needing to edit a ValueProxy in order to have all the data on the Serverside. I would really prefer to use RequestFactory over GWT RPC, but I don't understand why I first have to edit a ValueProxy in order to have its data available on the server (I understand I have would to do so using EntityProxies) . *b) Second Problem: editing a ValueProxy must be done in the same Request Context* The second thing I don't like is kind of dependant to the first problem described. I must edit the ValueProxy in the same Context and make all changes in the same Context. MyRequest *req* = requestFactory.edit(myValueProxy); myValueProxy.setAttr1(foo): myValueProxy.setAttr2(bar); *req*.myUpdateMethod(myValueProxy).fire(...) I have to do all this in the Presenter, if I dont't want to transfer the open Request to the View. That means, the presenter has provide a method with all editable Properties to the view...

Re: How to make a TextArea auto-growing...?
When you create the panel and want to render it, use:-
DeferredCommand.addCommand( new Command( ) {
public void execute() {
textArea.rightSize( );
}
});
where textArea is the ExpandableTextArea.

using eclipse GPE and WTP
hi, I am using google plugin for eclipse and start my tomcat server instance via the eclipse-WTP servers view. Basically it works, but the first start is quite inconvenient and I wonder, if anyone knows a better way to do this. so here is what I need do to start the gwt-app. when I checkout a clean version of my project, the war folder includes only the web.xml and WEB-INF folder. now I start my 'Web Application' run-configuration which has the -war attribute set to the war folder. when this starts up, it will create the MODULE directory in my war folder (which inlcudes hosted.html, etc.) but eclipse does not see these files yet: I have to manuall refresh my project. when I now start the browser (by dbl-clicking the entry in the Development Mode view, the .gwt.rpc files will be created in my MODULE directory. again I have to manually refresh the project in eclipse Package Explorer view now I can start my server and then I need to refresh the browser and everything will work. * when I start the server first and then the development, the files will automatically be copied to the web-servers exploded war directory, but the client-server communication will not work: I get SerializationExceptions cheers, martin -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT 2.2.0 HostedHtmlVersion.java, EXPECTED_GWT_ONLOAD_VERSION=2.1

How to integrate or call or interface with a 3rd party widget within a GWT app?
I am making an app in GWT. It is like a dashboard and will have out of the box widgets that I will provide. Now when we ship this out, there is a use case that the customer might want to create their own GWT widget and use this in the dashboard app. As I understand it, they will not be able to do this since we cannot ship our source code which is needed to compile the whole app again once tag of their widget/module gets into the gwt.xml file of my app. I cannot use anything other that GWT to make this dashboard. And their widget could be say a flash heapmap, a jquery widget/plugin, another GWT module, a jsp page that renders a visualization from back end. So far my thoughts have been to provide a widget in my app which is a wrapper in the form of an Iframe and call their main page (they will provide url), and have an api to let my app and their widget talk. But I would like to know if there are other / better approaches? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT 2.2 / RequestFactory - Can domain objects be interfaces as opposed to concrete classes?
Dear GWT Community, I am currently testing the RequestFactory framework in my current project. My question pertains to the domain objects that sit on the server folder of my gwt project and how I can best expose them to my client. I am trying to reuse one of my java libraries (I checked my classes were properly JRE emulated) that is made up of a spec (a set of interfaces) and an implementation (concrete classes implementing my interfaces). I would like to understand whether I can reference interfaces on my proxy classes (in the client folder) as opposed to concrete classes. For example, I've got an Order interface and an OrderImpl implementation. I would like my proxy objects OrderProxy (sitting in the client folder of my project) to only know about the Order interface. Of course on the server the OrderLocator instantiates OrderImpl returned as Order. I wasn't successfull so far, and it seems that GWT RequestFactory works only with concrete types during the serialization/deserialization process: it seems it is trying to restore an OrderImpl where I would expect to receive an Order, hence the run time errors I'm getting with this approach. I don't feel like rewriting my libraries to make them work with GWT RequestFactory, and would really like to understand whether their is an approach that could be used in this situation. Thanks for any info/inputs your may have on this topic, Regards, Frédéric -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT 2.2 / RequestFactory - Can domain objects be interfaces as opposed to concrete classes?
IIRC, the only blocker is the RequestFactoryInterfaceValidator (RFIV), which stops looping over super classes as soon as it finds java.lang.Object (and implemented interfaces come after Object in the list of super classes being iterated). This means it could be worked around by using a ServiceLayerDecorator that bypasses the RFIV (by re-implementing all the methods implemented by the ResolverServiceLayer; the hard thing then is to implement resolveClientType correctly). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: UI Binder Alignment problems
I had the same problem just a while ago, even though I had it with g:VerticalPanel horizontalAlignment=ALIGN_CENTER The reason in my case at least was, that UiBinder first adds the children, then sets the attribute horizontalAlignment, but horizontalAlignment is only taken into account for widgets added after the property is set, so it has no effect on widgets added in the template. This is actually fixed in GWT 2.1.1., because I had version 2.1.0. running and updated for that. Afterwards it worked as expected... Hope that helps, since I haven't tried it with g:cell ... and I don't know if the problems are related...

Window.Location and IE
Hello, everybody! In my application I want to send user to login page. I do Window.Location=./loginServlet; So, if my application is deployed to www.mysite.com/MyApplication user goes to www.mysite.com/MyApplication/loginServlet It works fine until i try it in IE. IE sends user to ''www.mysite.com/MyApplication/myapplication/ loginServlet Where 'myapplication' is the directory generated by GWT.

rightSize needs to be called when laying out a form, just to get

somewhere along the line the need for getScrollHeight has gone, but
I have not been following the API closely enough to see.
To get the full Notes function, one would also need to set the width

Hope someone can turn this into something that works properly.

Reading the jQuery plugin articles, this code may well not work on all

(I do not have a copy to test it with) whether the IE problems have

Re: How to integrate or call or interface with a 3rd party widget within a GWT app?
I think you are right that you can't do it. GWT compiles to just JS so could be possible but as I understand it the implementation of event handling only supports GWT being used once on the same DOM (it could be that it would work if the two GWT apps never use the same part of the DOM tree). So I think you are right about needing an iframe. Guess if you make the communication API abstract enough you could remove the iframe if GWT changes or you find a work around.

Re: How to integrate or call or interface with a 3rd party widget within a GWT app?
The official line is here: http://code.google.com/webtoolkit/doc/1.6/DevGuideOrganizingProjects.html quote: Loading multiple modules in an HTML host page If you have multiple GWT modules in your application, there are two ways to approach loading them. Compile each module separately and include each module with a separate script tag in your HTML host page. Create a top level module XML definition that includes all the modules you want to include. Compile the top level module to create a single set of JavaScript output. The first approach may seem the easiest and most obvious. However, the second approach will lead to much better end-user performace. The problem with loading multiple modules is that each module has to be downloaded seperately by the end-user's browser. In addition, each module will contain redundant copies of GWT library code and could possibly conflict with each other during event handling. The second approach is strongly recommended.

Re: Serialization Policy for a HashMap extension
Without more information, I would be hesitant to say you've found a bug. The RPC mechanism must be as conservative as possible in its estimates of what can and cannot be serializable, otherwise it would attempt to allow every widget to go across the wire. A few things to check – does the type which references your HashMap subclass declare it as a HashMap, or by name? If the latter, something else could be stopping your subclass from being available, such as it or a superclass being named in a set-configuration-property name='rpc.blacklist' / tag in any module? Otherwise, is it possible you are using the map to hold objects which are never named as explicitly reachable types? An example of this would be declaring a MapString, Object and storing various valid, serializable types - though they are legal to send over the wire, GWT can't tell for certain that you will send them, so it removes them. In this case, consider either adding an unused private field of the given type to the type that wraps this, or add the type name to the rpc.whitelist, ensuring that it may always be sent over the wire. Hope this helps - if not, more information on the usecase would be helpful to provide further advice. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: HandlerManager is deprecated and theres no removeHandler(...) method at SimpleEventBus class
Thanks for the link. I already had found that though. The threads I could find from that do say that HandlerManager will be undeprecated, but they convey it in a way that implies that they wish it wasn't necessary. I am left with the impression that there is a drive to get rid of HandlerManager, and I'm still left wondering why. Is it the particular implementation that is the problem?

Re: Problem with RequestFactory and two tier
Works for me in JEE envirnoment. Provide a locator, that makes a JNDI Lookup to get an EJB Session Bean. The bean can be implemented in a generic fassion, you only need to write a single Locator. That EJB must open a Transaction (with EJB3, the bean by Default creates one). Your data will be written to the Database. Question is, how efficient this will be, if RequestFactory calls the Bean too often... Sidenote: the problem I have is, that jee role-based security does not work with the generic locator (see my other post) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to make a TextArea auto-growing...?
Hey, I've taken a shot at this problem with pretty good results. Check out the code here: https://gist.github.com/833873 The textarea will stretch pretty reliably as the user types/cuts/pastes text. The way it does this is by maintaining an internal representation of characters-per-line. The only caveat is that you need a PX_PER_CHAR constant, so if the user changes font size or you use a variable-width font, it wont behave as expected. As for calculating the initial size, with this widget you can call setText(getText()) (or add your own init() method that does the same).

Re: How to make a TextArea auto-growing...?
We have a good implementation of both an auto-sizing TextArea (vertical) and an auto-sizing TextBox (horizontal) that automatically adjust to the CSS specified for the box (accommodating different fonts, line-height, padding, etc). I've been meaning to share it for a while and will do it this weekend. It's currently dependent on GQuery.curCSS to get the computed styles. I was hoping to remove that dependency before adding it to our gwt- traction library but since we use GQuery in other places, it hasn't been a priority for me.

Re: Problem with RequestFactory and two tier
Interesting that you work with an architecture similar to mine.

The problem for me is that the returned entity is detached and from the find all the RequestFactory framework works on that instance. All is done, but it will never written back to the database.

Re: How to make a TextArea auto-growing...?
observe the events of changes in text area, and yes, it can change size on paste. You can accurately measure the text, by putting the text in a html div, and get the divs width and height. Of course, you'll have to have a width contraint on the div, b/c you'll want to wrap the text in the div. You'll have to compensate for some factors like css and things that could affect html. Done right you can correctly get the pixel width to resize the input box. Hope that helps.

PreefixTree code question
I was looking at the code in PreefixTree to see if it would be
feasible to make it generic so I can pass it values other than a
String and noticed something that I thought was a little odd. See
init() in the following code snippets:
private JavaScriptObject stack;
public PrefixTreeIterator(PrefixTree tree) {
init();
addTree(tree, );
}
private native void init() /*-{
th...@com.google.gwt.user.client.ui.PrefixTree
$PrefixTreeIterator::stack = [];
}-*/;
This basically got me wondering why the developer chose to assign
stack with a JNDI call instead of doing the following:
private final JavaScriptObject stack = JavaScriptObject.createArray();
Is there something wrong with using JavaScriptObject.createArray() to
do this or was this particular function not available when the code
was written?
This is code from 2.2 BTW.
Thanks,
Pat

is RequestFactory and/or the Editor framework rendering the JPA optimistic locking useless?
I am thinking more likely the RequestFactory is rendering optimistic locking useless. The project is created with Roo with DataNucleus GWT. I wiped out all the generated stuff out and use the resulting Maven build as a starting point. I have been able to get a simple entity going and have a simple Editor allowing modifications and retrieval/update via RequestFactory. In the app I have been able to pile up newly generated Editor with the same entity, then change the same field one at a time and save it. Doing so I was hoping the backed JPA stack will give me an exception complain about update using a stale version. But to my surprise it isn't doing it. It just happily updated the record and bump up the version field by one without problem. Looking at the TCPIP trace, requestFactory's request is indeed only sending the modified field over the wire. So that means the RequestFactoryServlet must be quietly loading the current version of the entity from the db and merge the partial-update to construct the entity object that later passed to the persist method the caller instructed. Thus, the version would be fine even if the request was generated based on a staled but modified version of the entity. So my question to the GWT team, will this be fixed/changed? Or at least make it a configurable option that requestFactory will communicate and check the version automatically to ensure the optimistic locking works?

Re: How to integrate or call or interface with a 3rd party widget within a GWT app?
You can run multiple GWT apps on a page. Just include multiple script tags, and typically assign the RootPanel for each app to a different div in the page. They won't be able to communicate via Java, but they can communicate through global JavaScript variables and JSNI methods. Does that help? /dmc On Thu, Feb 17, 2011 at 4:42 PM, KD kanwald...@gmail.com wrote: I am making an app in GWT. It is like a dashboard and will have out of the box widgets that I will provide. Now when we ship this out, there is a use case that the customer might want to create their own GWT widget and use this in the dashboard app. As I understand it, they will not be able to do this since we cannot ship our source code which is needed to compile the whole app again once tag of their widget/module gets into the gwt.xml file of my app. I cannot use anything other that GWT to make this dashboard. And their widget could be say a flash heapmap, a jquery widget/plugin, another GWT module, a jsp page that renders a visualization from back end.

ServiceLocator and entities with collection
Hi all, I've found some difficulties in persisting entities with a ServiceLocator implementation. In practice the entity passed to my persist method doesn't contains data of the contained collection. I saw that everything arrives on the server (using a Network Monitor) but then when the entity is recreated the collection is not saved into it. To proceed in my work I created a method that takes the collection as a separated argument, but of course this is not the correct way to do this. Thank you for your advices.

Re: RequestFactory/Editor AutoBean has been frozen error
I think it was on-purpose: validation is done before any invocation is processed, so you can safely send the same invocations back to the server after making changes to the proxies so they validate the next time. I guess the idea is that you then only change proxies and fire the context again, without enqueueing your invocations once more. Failures however can happen at any time during invocations processing. Clearing invocations would work in many cases, but not all: you'll send the same operations, but the domain objects might have change as a result of a previous successful invocation (RequestFactory doesn't make any assumption on the use of transactions, so things have not necessarily been rolled back; actually in your case, our datastore –MongoDB– doesn't have that concept of transaction, and we successfully use RF with it; and similarly, AppEngine transactions are so specific that you won't enclose your whole RF request in a transaction), so applying the operations might very well fail (e.g. entity has been deleted, or its state has changed so that a setter now throws an exception). You'd probably rather want to copy the edited entities to another context. I haven't checked but it might be possible using AutoBeanUtils.getAutoBean and AutoBean.clone before a context.edit().

UiBinder + HTMLPanel + css = Loss of hair???
Hallo,
I have a weird problem, in my UiBinder template (suppose it's the
template for TestWidget) I have sth like the following code
ui:style
.fullSize {
height: 100%;
width: 100%;
}
/ui:style
g:ScrollPanel addStyleNames='{style.fullSize}'
g:HTMLPanel addStyleNames='{style.fullSize}'
div class='{style.fullSize}'TestDiv/div
/g:HTMLPanel
/g:ScrollPanel
But if I initialize
TestWidget test = new TestWidget();
SimplePanel testPanel = new SimplePanel();
testPanel.setPixelSize(800, 600);
testPanel.add(test);
RootPanel.get().add(testPanel);
I see that the ScollPanel indeed has the full size of 800 x 600, but
then in FireBug it shows a weird div with just position: relative; and
for all child elements the size is broken (meaning, the percentage
doesn't refer to the 800 x 600 px anymore...)
I tried for a ridiculous long time, to fix this, but I don't know
where I go wrong (since literally every f* tag should have size
100% and therefore I don't know where this ominous tag without style
comes from...)
Does anyone know what I'm doing wrong, and how to fix it? It' almost 5
in the morning here, so it might as well be a stupid mistake, that I
can't identify through my swollen little pig eyes anymore, but I
couldn't find rest, if I hadn't at least posted it here ;-)
About any help I'd be really glad...
Greetz,
Pete
