Re: TablayoutPanel - how to align tabs on right (top)
I would also like to know the answer to this question. My ui drafts are mocked that way. I figured that by the time I got around to doing layout that I'd stumble into the answer. I have t dug I to it myself yet but I am geting close to needing to know. I'm sure that I could just change the standard.css file but I hope that there is an official way to do this.

Re: Transferring an image over an PRC call
Is your goal to show the image in an img tag in the web browser? I
have user uploadable images on my gwt website and to present the
images to users i use an http servlet. I have an img tag rendered in
the client that references the image from the servlet. Since my
images are saved in the DB, the image servlet processes the users
request, finds the image that they are requesting and renders the file
to the output stream. Pretty much all you need to do is configure the
content type on the response.

Re: Do you always have an enormous front-prensenter?
Hm, when you say inject do you mean via Gin dependancy injection framework? Or are you talking about passing all of those child presenters in as constructor args? I'd highly recomend Gin for this task. It's pretty easy to learn and makes your code nice and tidy. On Mar 15, 2:54 pm, zggame wrote: > Hi, I am new to gwt as well as mvp.

Re: Question regarding presenter in MVP pattern
Feldman, Nir's solution is pretty much what i've decided to go with.
One thing i do differently though. I didnt care for the idea of
having one view having a dependancy on another so what i do is have
the "item" view offer up it's individual parts as widgets and have an
add row method on the containing view class which takes the number of
widgets necessary to represent the item. I went back and forth on
that decision and i think that it was right for me, but both ways seem
to be quite good at solving your problem.
I used this technique to have editable rows in a table it works pretty
well. Some cells hvae images in them and you can click the image to
swich from viewing the image to having the ability to upload a
replacement image. Each row is represented by an MVP composition and
the table is represented by another one.

Re: "pre" tags wrapping json response during image upload
Kudos sir, it seems that worked like a charm. I had the type set to text/plain in my servlet. What javadoc has this recommendation? I'm just curious. Is it in the doc for GWT somewhere or in the apache commons doc? I actually got my base implementation for the file uploader from the Google Web Toolkit Solutions book, and he called the issue a bug. ( I think that his book was written against GWT 1.3 ) I just assumed that it'd never been fixed.

Re: Referencing deprecated class warning stack
Hey, Thanks. I just noticed your update. That work around does resolve the issue for me. I had to also remove the old 1.7 dtd from the top of the xml file because i was getting errors because i guess that 'extend- configuration-property' is a new element. I couldnt find a 2.0 DTD and i see that the 2.0 generated projects dont contain a dtd. Does anyone know if there is one? Either way, black listing those classes does get rid of the warnings.

Re: Swing App on browser
2nd vote for webstart. Webstart is the answer. GWT would make for an easier conversion path for a swing developer to web development but i think that you have to have a pretty solid grasp on the fundamentals (limitations and techniques) of web development to produce effectively in GWT. There'd be no way to do a straight conversion of a non trivial application.

Re: MVP design help for Display interface
My solution to this problem was to create one presenter/view pair for the table as a whole and then a seperate presenter/view pair for the rows. This way the Cell click handlers are all in the same context. The table presenter gets new row instances from gin and initializes it by passing in a backing bean, that row presenter then exposes the cells as widgets which can be added to the table view.

Re: Is it possible to have a resizable FlexTable
I saw your message and my gut reaction is that you should probably be
doing this in css. As far as the browser is concerned it's just a
table so having it react to the browser resizing should be easily done

Re: DatePicker / set a minimum date

Re: Customizing RichTextArea with insertHtml in GWT 2.0
Hey thanks,
I've seen that post which was what turned me on to RichTextToolbar
when i started to research this a couple of days ago. It looks great
and will definitely be the inspiration for how i create mine. The
problem is i want to do custom functionality that the raw Formatter
object doesn't supply. (custom youtube and embeding and a few more
things) which i can do just perfectly with insertHTML. The problem
is, i want to grab the text that the user has highlighted so that i
can use it when i insert the custom html but the API doesnt seem to
expose it. The custom RichTextToolbar implementation just calls
methods on RichTextArea and never actual seem to touch the selected
text directly. It just calls things like
RichTextArea.Formatter.createLink... which hands wrapping the selected
text internally.
I just wrote a hack work around for the time being so that i can
progress to other work but i'm still convinced that a getSelectedText
method exists somewhere. If it doesnt, it certainly should.
Here's the workaround that i just came up with:
private String crazyGetSelectedText(RichTextArea
rta) {
final String MARKER = "http://trevsmarker.com";;
rta.getFormatter().createLink(MARKER);
String withMarker = rta.getHTML();
int markerIndex = withMarker.indexOf(MARKER);
int beginIndex = withMarker.indexOf('>',
markerIndex)+1;
int endIndex = withMarker.indexOf('<',
beginIndex);
String selected =
withMarker.substring(beginIndex, endIndex);
rta.getFormatter().removeLink();
return selected;
}
That seems to get the job done but how horribly inefficient is that
solution?

Customizing RichTextArea with insertHtml in GWT 2.0
I'd like to create a custom rich text aera. I think I I've got a fair handle on how it works from playing with the showcase RichTextToolbar source code. The Formatter.insertHtml method seems like it will get almost exactly what i need. But, there is one critical peice of the puzzle I have yet to solve. I need to grab the text that the user has selected to make the HTML inserts work he way I need them to. Am I missing it?

Re: File Upload Problem
I didn't look at your logic very closely but I did spot one problem...
maxFileSize = 10*(1024*2); //10 megs max
That isn't 10mb. It should be 10*(1024*1024)

Re: Why History.newItem() always calls the onModuleLoad?
I'm glad you asked this question! I've just assumed that you had to fire the change event when adding to the history stack with addItem. I guess you probably saw it but your answer is simply use the two argument version and pass in "false" for the issueEvent argument.

IE Development plugin not working in 64-bit vista.
I decided to create a new, more descriptive conversation. It seems as though the IE development plugin does not install properly in 64 bit vista. Is this issue being addressed? Does.

Re: GWT Developer Plugin not working IE8
That's the conclusion i'm sticking with until told otherwise. I've
wasted a good 2 hours today trying to get it to work on my dev box
with no luck.
The dev plugin so far seems amazing in ff. Should make development go
much faster when making minor changes. I hope they figure out what's
wrong with Vista 64 soon.

Re: GWT Developer Plugin not working IE8
Oh and i cant find an oophm.dll anywhere on my system. Where should
it be?
I dont see any errors in the event viewer either. Install runs fine
from within ie and directly from the file system. Both run and give
me a success message but nither seem to work. I restarted ie multiple
times and rebooted the PC.

Re: Creating new methods for Async class
Not to complicate matters but using ArrayList instead od List supposed
to be better in gwt? I could have sworn that ray ryan alluded to this

I still don't do it because I hate seeing that in my code but still,
ymmv

Re: Creating a sample application of 3 different pages
Looking at the variety answers here i have to wonder if i'm not
missing the point of this question because as far as can tell none of
them go straight to the heart of the issue. In GWT i think that the
default/defacto/best practices way of showing multiple pages it to
operate purely in GWT. You have one html file with one entry point.
The html file has one div in it with a known id. You use that element
id in GWT in a RootPanel.get("..."); call and then you add your GWT
widgets to the returned widget.
When you want to switch from the login display to a list of elements
you do the exact same thing, do a RootPanel.get("..."); and add your
new widgets to it.
Once you get a simple thing working like this you want to learn about
how GWT does history. I found History to be a pretty odd thing to get
a handle on since it comes for free in traditional multi page web
development but once you get a feel for it, it makes perfect sense.
Good luck.

Re: CommandPattern vs Server side Event Bus?
The enherent problem with having a server side bus that talks to a client bus is that the server can't initiate the event. . (due to the non-push nature of the web) but the second issue is that a client bus services one client where as the server bus would need to service many. Questions spud arise like can a server event fire to a specific client or only to an individual client? In the application that I'm developing I have a polling thread in the gwt client and an event broadcast system on he server to allow the server to notify clients of notworthy activities. I don't use a bus on the server to handle requests though I just use RPC and command pattern.

Re: GWT + mysql (noob questions)
>It sounds like hibernate, when integrated into my app, allows me to avoid >having to worry about the lower level SELECTs & parsing results etcetc? That is true for the most part but as Charlie said it's not a pure win because getting it to do what you want, how you want it to do it can be very tricky. I've been using it for oh, maybe a year and a half now and i still feel like i'm just getting my arms wrapped around it. I haven't really dug into IBATIS but it sounds like it may be an easier to use ORM. For me, the hibernate full text search is very valuable. It can be very fast but you really need to understand how it works to get it to do things right. The way the handle lazy instantiation often feels obtuse to me and i'm continually getting a better handle on it. There are a few books out on it if you're really interested as well as a lot of documentation online. If you do use it just never trust that it will query for data the way you expect it to. You have to stay on top of it or else it is very easy to cause situations where it will query repeatedly for data that you should be able to get with one round trip. On and BTW, i'm also a huge fan of the MVP pattern. I'm very glad that i saw Ray Ryan's presentation before i got to far into my project. He saved me from having to write a *lot* of boilerplate code. Are you also using Gin? I was reluctant at first because i was getting framework fatigue but it is pretty handy for being able to unittest your presenters.

Re: How can I have a function in my button call back, call a function in another class?????
Instead of defining the callback as an anonymous inner class you could
make it a regular class and pass an instance of the class containing
the method that updates your data into the constructor of the new
callback instance that you create before passing it to the RPC. Then
when the response comes back from the server you could simply call
it.
You could also call the method directly from the anonymous inner class
but there are some limitations as to what an anonymous inner class can
call from the outer class.
Side question, what is that 5 sec timeout for? You're not trying to
wait for the rpc to finish are you? That's bad voodoo. Async is not
your enemy.
Also, one other question what's with the 'onResponseReceived' why not
just use onSuccess?

Re: GWT + mysql (noob questions)
I dont have any tutorials at hand but your understanding of where the DB code lies is correct. It's totally on the server side and has nothing to do with GWT. Your GWT app would get access to the data via RPC. The RPC methods would in turn get data from the DB. Hibernate is an ORM (object relational mapper) which allows you to tie Classes to DB tables in a way that is largely transparent to your application. One problem though in using hibernate with GWT is that the classes created via hibernate cant be serialized to the client via RPC (not that i know of anyway) so a lot of people use different libraries to make clones of the faux-POJO's so that they can be serialized. (I do this in the project that i'm working on but i did it by hand) (um, POJO means plain old java object). If you're interested in using hibernate you should probably use it from the start because retrofitting the application after the fact would on undoubtedly be extremely painful. But with that said and with as much as i love hibernate if you're using all of these new technologies together for the first time you may become overwhelmed and hibernate is a fairly involved framework so you might be better off getting a good grip on GWT and GWT's RPC mechanism first. but as always, ymmv On Sep 23, 10:53 am, PJ Gray wrote: > I am writing a fairly large web app using GWT in Eclipse.

Re: Why Not Bypass The Middle Man
> Would it be that hard to get the general public to accept a new internet > that involves application browsers? I think that you dramatically underestimate people’s reluctance to install something new. It took a long time for the web and its protocols to reach the levels of saturation that they currently have. Trying to create a brand new one would just about be an exercise in futility. But about GWT specifically... think about it like this. GWT is the evolution of web development. It does what computer languages and development technologies have always done. They took a look at what was needed Javascript, CSS, html, Ajax and they encapsulated it allowing the developer to compose solutions to their specific needs without (or with little) regard for the underlying complexities. Compare that what a high level language like C or Fortran are. They allow you to compose solutions to your problems in relatively easy to manage functions. You don’t care what it takes in assembly language to get user input from a keyboard you just create an input stream. This level of encapsulation is what GWT brings to the table for the web and in my opinion it is simply brilliant in its execution. I’ve been doing web and app development professionally for over 12 years now and I can’t remember the last time I was this excited about a new technology. I find that being able to compose web UI’s with a rich programming language to be liberating. Now that I’ve gone completely off track, to address your concern more directly: what would a new protocol mean for me as a developer? If all it provides is a way for me to execute Java (or some other high level language) on the client then for one thing it’s not really giving me anything fundamentally new. Especially if the UI Widget set was still based on Swing or AWT or the like. What it really does is limits where my app can be used because no one (or very few people) will have the ability to connect to it. The inherent ability to push from the server is pretty trivial in comparison to not having an app that can be used by the majority of people without requiring them to install new software and potentially modify firewall or other hardware settings. I mean, I’d rather just fake push by polling the server and have it usable to everyone. Ajax makes that trivial. And GWT makes Ajax trivial.

SuggestBox manual override?
I have a suggestbox with a custom oracle. In some instances i would like to be able to automatically cause the suggestions to pop up just by the user setting focus to the suggestbox for instance. I figure that i should be able to use a FocusHandler to do that part but how do convince the thing to request data? I tried getting the oracle and calling the requestSuggestions method but what do i pass to it? The callback function is the problem. I need a call back that will actually populate the suggestion list. Am I going about this the wrong way?

Re: Creating a wizard - Series of steps with GWT
GIN is a DI framework that works with GWT
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/f6f13ebc2c59a64e#
The fact that the client code is compiled into JS before execution
makes GWT UI's a unique beast. GWT has a lot of Java's functionality
but you cant include libraries that haven't been compiled to JS.

Re: URL and GET method
Like Sri is saying here, i think that you're probably missing the
boat. Find an article to see an example of History in use. And in the
words of Ray Ryan, get history right early!
It feels obtuse at first but it eventually comes together.

Re: Seriously getting beyond my capabilities with GWT....
imho, the purposes of forums like this isnt to find someone who will help you off line but to share questions that others may have so that they can be answered in on central repository. Further the questions and responses could possibly guide future development and documentation. To that end i think that questions in this specific forum should be GWT specific not development in general. That my opinion anyway.

Re: Where is the server log ?
This isnt a direct answer to your question but i think that this is
the root of what is going wrong. Class instances that you send to the
client have to play by the rules of GWT. The class cant have imports
that are not available on the javascript runtime code.
import javax.persistence.Entity;
import javax.persistence.Table;
those classes are almost certainly not in the limited environment.

GWT Stackpanel, load panel content dynamically via RPC?
So with TabPanel there is an addBeforeSelectionHandler() method which allows me to show the tab header and delay loading the content until the tab is selected, how can i do this same thing with StackPanel? I don't see where i could hook that in. What i'm considering is creating a set of nested stack panels that generate themselves dynamically. When you click a panel header, it makes an RPC call to see if there is a need to show a sub-stackpanel, or content. I guess i could do something similar with a tree (using the addOpenHandler() method) but stack panel i think would work better for how i'd like to interact with it. I guess worst case scenario could perhaps create a custom component which detects if it is being shown, and then have it populate itself via an rpc call... But it sure would be nice to have an event fire when the panels in the stack change. I haven't found much info on onBrowserEvent, i wonder if that would help? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Hosted mode doesn't work at all on my Vista notebook under Eclipse
I've been developing pretty heavily in GWT on my desktop for the past month, tomorrow i'm going on a trip and trying to get my notebook ready to do builds. For the life of me i can not get GWT to work with it. I tried to get it working with MyEclipse 6.01 (Eclipse 3.3.1) and it didnt work so i upgraded to MyEclipse 7.5 (Eclipse 3.4.2) i added the latest GWT version and eclipse plugin and it still does the same thing. I can create projects, compile them but i can not launch hosted mode. The Jetty browser and hosted server launch but i get an error in the browser and nothing but a simple message in Jetty "Starting Jetty on port 8080" (with two success messages beneath it) What is going on? I don't think that jetty is accepting requests. This is on Windows Vista 32 with IE8. Things were flawless on my desktop so i'm at a loss. I can create a project and compile it but if i launch hosted mode i just get an error in the browser. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Problem creating a RPC Service
I dont think that you're looking at your problem right. For starters GWT and AppEngine are to totally separate and unrelated things. If you don't intend to host on AppEngine you probably dont need to develop with it. Using RPC's to add lines of text to a file sounds like a really bad idea. Like everyone else is saying, use a DB. AppEngine should make persisting the info to a DB about as simple as it gets. (if you want to use it) When you're ready to pull down the user entered code to compile it you can use an admin GWT page (or a simple servlet) that you would create to read the text from the DB, and send it down to you so that it can be compiled. If you wrote the retrieving component as a servlet then you could set the page content type to plain/text and write the text directly to the response which would give you a file save dialog when you try to retrieve it. Just my quick though to solving the problem, ymmv.

Re: fileupload: ensuring the same file being uploaded
This book as a chapter which holds your hand through file upload in
GWT with Apache Commons: http://coolandusefulgwt.com/
The book is a tad out of date but still helpful.
Here's an online example using apache but you'll still need the stuff
to create the form on the client side to initiate the upload from
gwt. I'm sure that there is an example online, but i'll leave that
googling to you.

Re: Save form data
I think that you may be mixing things up a bit. RPC doesn't use true
html forms. So what would look to a user to be a form in a typical
GWT application would just be a group of input html elements and a
button. The button doesnt submit a form, it has a click handler. The
handler makes an RPC call to passing the user entered data to the
server.
GWT does have a FormPanel widget thought which allows you to make true
HTML forms. Those can submit to any webserver configured to handle
the http request. I think that these kinds of forms are included to
support legacy back ends and to do things that GWT RPC cant like, oh
say file upload.
ymmv, i'm still pretty green with GWT but i'm coming up to speed.

Re: Admin Area protected by simple scripted password in GWT
Some good info in that link, Isaac, thanks. "Do NOT attempt to use the Cookie header to transfer the sessionID from GWT to the server; it is fraught with security issues that will become clear in the rest of this article. You MUST transfer the sessionID in the payload of the request. For an example of why this can fail, see CrossSiteRequestForgery. " Hm. Well, ok then... i guess i should heed that warning. The article doesn't seem to directly address Nickelnext concern about having the admin content already in the browser though. I mean, once you compile the UI into javascript and the browser downloads it, everything that the view does is there in the browser. It seems pretty far out there that someone could use that obfuscated javascript mischievously but that's what hacking is all about, so i hear!

Re: Admin Area protected by simple scripted password in GWT
Ah, I understand your concern. Hm. Maybe someone with more GWT experience can chime in on this but i'm thinking this. It's not like you have a simple hidden DIV in the browser that you're deciding to show dynamically. You have a javascript function that generates that div, which i'd imagine would be a lot tricker to hack (though probably not impossible if the hacker were properly motivated) Even still, what would the hacker have access to at that point? He'd see the admin tab... but what could he do with it? You should implement your security so that the admin RPC methods also require some kind of authentication. This way, a determined hacker may be able to see the tab but he still couldn't do anything with it. Not knowing your exact application, this may have other complications but that is the way that i'd probably be thinking of doing it. I'd love to hear some alternative solutions as i'm pretty much in the same boat as you are. I'm porting my first major application to GWT and i've been going with the assumption that server based security for the admin RPC's combined with obfuscated javascript will give me a similar level of security to what i would get by traditional means. (though arguably better since there will be no history trail to the admin pages left in the browser since gwt allows you to not cause any browser history footprint that you don't deliberately generate) On Jul 29, 12:27 pm, Nickelnext wrote: > Hello > > You suggest that when the callback gets the Onsuccess and the user is > valid, i can simply add a new tab or panele or whatever making the > Admin Area visible? > > Your solution would be perfect, and i thought of it yet but my > question is: isn't it easily hack-able?

Re: Multiple pages question
I think that the issue that you're running into here is one of mindset. Web developers think in terms of pages but a Swing/MFC/thick client developers dont. GWT is kind of a bridge between the two. >From what i've seen, the GWT way of doing things is to clear out the visible components and render your new components to give the user a different view. (like you said) Now is your question "how can i create these two views in separate java files" (which is an architecture question) or "how can i separate widget (element) composition from Java" which is almost a philosophical question because GWT (at least as far as i've seen) is not designed to operate that way. (which i believe is a design feature, not an oversight) One other fly in the ointment that you may not have stumbled into yet which will blow your mind at first is using the back button. There is lots of documentation out there on using GWT History and it's really a different way of thinking coming from a web developer perspective. ...if you are asking the architecture question, so far i havent seen much yet on best practices for organizing your classes and widgets but you should start by searching for 'GWT Custom widgets' and specifically checking out the Composite class. That should get your started in how you can organize and compose your various views. Disclaimer... I've only been using GWT for about a month now but i've been doing Swing/Visual C++/VB gui's for a long time and to me GWT fits as naturally as anything i've ever seen from a web framework perspective. But it is very different from Swing, Spring MVC, JSF and the like.

Re: Admin Area protected by simple scripted password in GWT
I take it that regular users for your application dont have to authenticate, but you want the admin to login and then show him or her a different view (a view with an admin tab)? The question is kind of broad, i mean allowing a user to login is pretty much nuts and bolts stuff. You put together a widget with text and password fields, give them a button to click (or respond to the enter key) and then make an RPC call to the server where you'd authenticate them (using a db, text file or hard coded value or whatever you want). Once the RPC call returns successfully you can rebuild the tabs or just add the admin tab. Should be pretty straight forward. Do you have a more specific problem?

Re: onSubmitComplete is not working with GWT Showcase
Shot in the dark here but the first thing i would check is are you setting the method type on your form panel? Sounds like you need to set it to "POST". (FromPanel.METHOD_POST constant is defined for doing this) Trevis On Jul 28, 10:15 pm, Simon wrote: > Hi all, > > I have a problem regarding FormPanel.

Re: Save form data
I dont have an example handy but i have to imagine that there are plenty out there. Sounds like you already have GWT creating the forms, so i assume that you are setting the encoding type and post method already. I guess you have also created a FormHandler and added that to your FormPanel. Form there, GWT is (can be) out of the equation. The responding server can be anything. All you should have to do is call setName() on your form elements and your server should be none the wiser that you are using GWT on the front. (I have not implemented this yet myself as i am deeply in love with RPC, but i have been reading about using traditional forms with GWT because i need to implement image uploading which i plan to do with Apache Commons fileUpload) Trevis On Jul 29, 6:47 am, Jeremiah Moses wrote: > Hi > I want to save some form data into my database my forms are generated using > GWT and i already have code that interacts with my database, now my question > is how do i interact with this code ... is RPC the only way to do it in GWT > or is there any other way to integrate my gwt UI to this my existing > code can save to the database and retrive information so all i need to do is > send the info to it using the form generated in GWT any examples with > regards to this are welcome > > thanks > > Jeremiah Moses --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Can I invoke RPC Methods from Java
I'm still pretty new to GWT but i'd probably start by watching the messages in firebug (the firefox plugin) to see exactly what's going back and forth.

Re: Stack overflow at line :0 (Hosted mode memory error)
Yeah, it doesn't seem to cause any problems but it sure is annoying. I guess using the trunk build would be less traumatic than switching to linux. Someday hopefully we'll all be on linux but we're not quit there yet.

Re: Can I invoke RPC Methods from Java
I'm also pretty new to GWT and your scenario never occurred to me. Generally i think that it's probably not the greatest idea to try and call the GWT RPC's from a different front end and i've not come across anything that would give you a wsdl (or something like a wsdl) that you could use from non GWT java app. But, i cant think of any reason why you couldnt make it work. The RPC calls are just HTTP Post requests which receive a JSON response. Introducing JSON into a non web app seems like a red flag to me but if you really wanted to do it, you should be able to convert those into java objects. I *think* that a better solution might be to just rewrite a SOAP based webservice layer that uses the same code that the GWT services calls. That's not a great solution either since it introduces duplication but perhaps a better way to go would be to port the logic to a SOAP based webservice layer and then call the SOAP service from the GTW RPC server so that the logic only exists in one place. Just a thought, ymmv. On Jul 29, 9:38 am, Steve wrote: > Hello All, > > I'm new to GWT so please forgive me if there is some obvious answer to > my problem.

Stack overflow at line :0 (Hosted mode memory error)
I've been developing in GWT for about 3 weeks now. At first i just wanted to get my feet wet and maybe port a minor dynamic piece of my site to GWT but i'm so blown away by the technology that i'm considering a full UI port. So far the one issues that i can not seem to resolve is this "Stack overflow at line :0" popup message that happens when i launch the code in hosted mode. I know that i'm not the only one who has the problem and i've seen blog posts where people talk about having resolved it by modifying the memory settings that it uses but nothing seems to work for me. I'm using Eclipse and have seen this message with GWT 1.6 and 1.7. The hosted browser takes a long time to render my content and then i get that popup. It works fine if i compile it and hit it with a real browser. It seems strange to me that the popup says "Microsoft Internet Explorer" but i guess that's what's being launched internally. How do i make this go away? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
