Re: Is there any way I can add a Chart widget into cells in a celltable?

[-sowdri-]

Cells and widgets are 2 different ways to render info on the screen. While 
the former uses innerHtml, the later uses DOM level manipulations for 
rendering the data. 

There is a proposal to come up with cell backed widgets, I'm not sure about 
the implementation roadmap.
refer: http://code.google.com/p/google-web-toolkit/wiki/CellBackedWIdgets for 
details. 

I'm not sure why you are trying to embed widget in cell table. But if you 
really have to do it, try image charts (
http://code.google.com/apis/chart/image/ ). You can create custom cells for 
each of the chart type you use and you can embed this into the celltable. 

But you will lose the interactivity though :(

Hope this helps,
-sowdri-

Hi Thomas,

Re: Stuck in the StockWatch tutorial

[-sowdri-]

>> RootPanel.get("stockList").add(mainPanel);

// From the javadoc

public static RootPanel 

 *get*(java.lang.String id)

Gets the root panel associated with a given browser element. For this to 
work, the HTML document into which the application is loaded must have 
specified an element with the given id.

*Parameters:*id - the id of the element to be wrapped with a root panel ( 
null specifies the default instance, which wraps the  element)*
Returns:**the root panel, or null if no such element was found*
Looks like your host html is missing an element with id "stockList", so 
either add it to your host page or Use the following line, without the id 
param, 

RootPanel.get().add(mainPanel);

Thanks,

Stuck in the StockWatch tutorial

[thronedoggie]

Okay, I can keep retyping the same things over and over, or I can ask
for help.

(Actually, I'm doing both : )

I'm in the sample app tutorial -

http://code.google.com/webtoolkit/doc/latest/tutorial/gettingstarted.html

- building the StockWatch web app. I'm using Indigo build id
20110615-0604. I typed it in just like it said and everything was
fine, then finished section three ("Build the User Interface" and
then, when I tried to run the test, Church was Out.

That line is

and it all looks just like the example - EXCEPT that the .get in the

Tried some googling - couldn't find out what the italics mean.

If anyone has any ideas, I'd love to hear about it. I was having fun
with this until this happened, and I can't find any way around it.

thanks,

Is there any way I can add a Chart widget into cells in a celltable?

[Jian Lu]

Basically I have a chart widget created as documented here:
http://code.google.com/docreader/#p=gwt-google-apis&s=gwt-google-apis&t=VisualizationGettingStarted

The problem is I need to add this chart into my CellTable, and CellTable
doesn't take Widgets.

Is there anyway I can achieve that?

Thanks!

GWT Locale does work in address bar, does not work in meta

[Jesse]

Hi

I have a gwt portlet with (for now) localization in English (default)
and Dutch.

If I put ?locale=nl& in the address bar, I get nice Dutch texts.
However, if I put  in
the head of my html file, without any reference to locale in the
address bar, I get the English texts. When I look into the rendered
html source, I can see the  tag. According to the documentation
it should give Dutch texts.

Does anybody have a suggestion about where I should look to fix this?
Obviously my locale is working, but it disregards the meta property

With kind regards

Jesse van Bekkum

Re: transfer Objects between GWT and EJB

[Mark]

I dont know that you can do that directly.  The best way I know of is
to create a pojo to represent the entity on the gwt side and then
translate back and forth between them.

Re: Activities and Places - Ant compilation

[Thomas Broyer]

Well, if it compiles with the GPE, it's likely an issue with the Ant script, 
right?

It looks like the client-side classes haven't been compiled (javac) or that the 
output from javac is not in the classpath for the GWT compiler.

Re: Ideal development platform for GWT/GAE?

[Ashton Thomas]

I moved from Ubuntu to MacBook to a very recent MacBookPro. A good 
processor and a bit of memory for dev mode really helps. My new machine is 
a beast which makes me smile to run in dev and compile my GWT app. 
2.5i7quad/SSD/8gbMem. Dev mode screams on this thing. And it compiles the 
app for production like it is opening Chrome. It bankrupted me but I don't 
regret it since I am working on a pretty big project which was painfully 
slow on my previous machine. At times: Eclipse uses 1.2+ gb memory and Java 
and Firefox take almost another gb. (what's the point in having it if you 
don'e use it..)

transfer Objects between GWT and EJB

[ph09]

Hello,

I have got a question because of the architectur of my project.
At the one side there is a GWT Package with the Client Side and also a
Servlet to communicate with an EJB Project.
On the other Side there is a EJB Project with Session Beans and
Entities which schould be stored in a database and send between GWT
Client and the database. But I don't know how I can realize that. how
can I send an Object from my Session Bean to the GWT Servlet, because
the GWT Servlet don't know about the Entitities Classes.

Thats my Project Structur:

Entities + Session Bean:
http://pastebin.com/anAbCqgd

GWT Servlet:

GWT 2.4 crashes in dev mode on IE 9.0.8112.

[nemo]

Anyone know of a workaround? This problem was first described almost a
year ago in:

http://googlewebtoolkit.blogspot.com/2010/12/support-for-gwt-dev-mode-in-ie-9.html

It was supposedly fixed in GWT 2.3, but it still crashes in 2.4 on IE
9.

History change event fired in Chrome for no reason :(

[Ed]

Hi,
History works weird in Chrome and I can't debug it as I get lost in
hosted mode code but I can reproduce the error in web mode in Chrome
and not in FF. It works fine in FF.

Situation:
I have a display that shows a form in show and edit mode with
respectively history marker h1 and h2.
When going to view  mode, I set a history marker manually through
History.newItem(marker, false) (note that argument false specifies to
not fire a History value change event). The history marker h1
correctly shows up in the url (and no History change event is fired).
When going to edit mode, I do the same, set the history marker
manually and it shows up as h2 in the url.
I then press the save or cancel button such that I go back to the show
mode. In code I do the same as above: set the History marker h1
manually.
Now something strange happens in Chrome (not FF): it shows h1 in the
url just a moment and then it fires (for some reason I don't
understand and can't debug) a History value change event (coming from
the HistoryImplSafari implementation class) with as history marker h2 :
(. It's like the back button is clicked, such that the application
shows the edit view again and the marker h2 shows up in the url (just
after showing h1 for a moment).
Apparently the history value change event is fired asynchronized (in
FF the event isn't fired).

Anybody any idea why this event is fired?
For me this is beginning to look like a bug.

I debuged every action, and all of a sudden this history change event
shows up for no reason... just like a back button is pressed.
I hope somebody can give me some hints what this might be.

I am about to implement a hack for the moment: a timer that will
ignore this value change event...
Note: FF works great and correctly shows the h1 and h2 markers as
expected (also when using the browser back and forward buttons).

- Ed

Re: Ideal development platform for GWT/GAE?

[Tomi B.]

Hey Mark,

>From anecdotal evidence Ubuntu has been the fastest with our code base. 
We've got developers on Windows 7, OSX, and some on Ubuntu. There has been 
a striking difference in compile times on the Ubuntu machines on comparable 
hardware (much faster). Personally, I'm on Win 7 64-bit. On the same 
hardware, moving from 32-bit to 64-bit dropped compile times to almost half.

GWT Canvas ImageData requires multiple reads to get value

[Maiku]

I am wondering if anyone else has encountered this and if so is it a
bug or simply a misunderstanding on my part of how Canvas's ImageData
works.

I am trying to implement a simple hit detection on my canvas where
each graphic in a list is drawn in a solid colour representing its
index in the list. As I go through the list, I check the Alpha value
at the current mouse coordinates to see if they hit the graphic just
drawn and if so I return that graphic as the one that was selected.

The problem I am getting is that after getting the ImageData from the
Canvas and calling imageData.getAlphaAt(0, 0) I always get 0. After a
bunch of testing I found that if I call it multiple times in a row (at
the same location) I will eventually get the correct value. My code is
like the following:

 hitContext.clearRect(0, 0, CANVAS_WIDTH, CANVAS_HEIGHT);

  List graphics = listener.getSymbolList();
  for (int i = graphics.size() - 1; i >= 0; i--)
  {
 graphics.get(i).draw(hitContext, i);

 ImageData imageData = hitContext.getImageData(x, y, 1, 1);

 // The coordinates for getAlphaAt are those of the imageData
not the original canvas.
 int alpha = imageData.getAlphaAt(0, 0);// first time this
method is run, this always returns 0. afterwards, returns expected
result
 alpha = imageData.getAlpha(0, 0);   // also returns 0
 alpha = imageData.getAlpha(0,0);   //  returns
correct value


 if (0 < imageData.getAlphaAt(0, 0))
 {
 
 }
 }


So is this a bug in GWT or is this call assumed to be asynchronous
(although not stated as such) and if so how should I be handling it?

Re: How can I trap for a 404 in my GWTTestCase?

[laredotornado]

Thanks, the trouble I'd have is that the FormPanel exists within my
Composite component

 final ProductDetailsView productDetailsView = new
ProductDetailsView();

which is client code.  That is, I can't put JUnit directives in
there.  Does that make sense?  The form panel within there already has
a submit complete handler associated with it, so I'm not sure if I can
override that from my test case.  Ultimately, I just want to see if
the form submission resulted in a non-200 response.

Thanks, - Dave

Just like you're "waiting" for getNode to get back, but here using events: 
add a FormPanel.SubmitCompleteHandler to your FormPanel and only call 
finishTest from there. The handler will be called when the server responds 
to the form submission, so either it works and you can have asserts and 
then finishTest() (in the normal case), or it somehow breaks (there's 
little to no reason, but who knows) and your test will fail in timeout

Re: How can I trap for a 404 in my GWTTestCase?

Hi,

I know, I'm not waiting for result of submitting the form.  How would
I change or add to

saveButton.click();

that submits the form, that would wait for the
FormPanel.SubmitCompleteEvent?  Thanks, - Dave

Re: Troubles getting DataGrid to show

Hi,

See
http://stackoverflow.com/questions/7874168/solved-gwt-datagrid-automatic-height
.

You need in DOM tree, in some point, a fixed region that is the parent of
the DataGrid, or attach to html body element the RootLayoutPanel. I had a
problem recently, check T.Broyer suggestion at this
thread
.

Troubles getting DataGrid to show

Hi,

I have a TabLayoutPanel and in the second tab, I would like to display a

tried (among other things) this :

Unfortunately, only the header is showing, no data.
When I replace DataGrid with CellTable in both the uibinder xml and my

Re: How to implement admin features/sections in app

[Drew Spencer]

Hey everyone, and thanks again for the help.

You have all given me lots of advice on security, which is something I 
don't have much experience on, so it's greatly appreciated. I am securing 
my server-side calls at the moment, and decided that as there will be only 
one or two admin users, it was best to add those UI elements in dynamically 
as otherwise everyone would have extra overhead that they didn't need.

As for the code splitting, I think that's a bit too advanced for me atm, 
but as my application grows it could become a possibility.

Thanks to you all again.

Take a look at your server log if there are some warnings or even

Issue with Custom exception in Production mode

[Nagin Kothari]

I have defined custom exception  extending from Exception class. On server
I throws this custom exception with some message.
My RPC call also has this exception  as part of service call signature. In
development mode when I show this message  in "onFailaure()" method of RPC
call on client,
I see proper message. But in production (after compilation)  , on client I
see 500 error instead of message.

Any idea could be the reason and how to resolve this?

Thanks ,

Re: How can I trap for a 404 in my GWTTestCase?

[Thomas Broyer]

You can't. Or rather, you only have access to the response page's body, so 
if you can identify a 404 from that, you're done.

BTW, your test actually isn't even seeing the 404, because you finishTest() 
just after you saveButton.click(), so the form is submitted (actually 
probably just after the code yields to the browser, so *after* the 
finishTest()) but you don't wait for the FormPanel.SubmitCompleteEvent; so 
it's expected that your test pass.

Re: How to handle Browser History using UiBinder ?

[saida dhanavath]

Hi,

If you follow MVP or not is not a big matter here, I suggest you to use
GWT's Activities and Places framework built only for history management
needs.

As Thomas said, UIBinder is nothing to do with history management.

If you which widget container needs to be bookmarked, You can write Place
and Activity for that widget container and put all of the onModuleLoad of
your module and that's it ActivityManager manages the tokens and getting
back the previous status of the UI.

http://code.google.com/webtoolkit/doc/latest/DevGuideMvpActivitiesAndPlaces.html
http://www.slideshare.net/turbomanage/secrets-of-the-gwt

above link helps you in writing Activities and Places, remember your
application need not to follow MVP always, but its best practice to manage
the application well.

Regards,
Saida.

Re: MySql Connection Problem

[Ahmet Dakoglu]

I had the same problem and find out that if you use GAE in your project
this error occurs so it is not related with your url format.
