Re: different behavior on chrome and firefox

[kozura]

PopupPanel documentation has a lovely example:
http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/ui/PopupPanel.html

For positioning it, instead of the roundabout positionAndShow that
they use, can probably just do:

popup.setPopupPosition(textbox.getAbsoluteLeft() + 10,
textbox.getAbsoluteTop() + textBox.getOffsetHeight());
popup.show();

Re: Compound properties

[Paul Robinson]

What you're missing is the gwt.xml construction that lets you make
properties depend on other properties.

Create a new property like this:


Then get GWT to calculate your log_level property from the new prod/dev
switch:

  



  


and do something similar to set up the stack trace emulation from the
compile mode too.

Then you just need to switch the compile mode, and the other things
switch automatically from that.

Enjoy :)

Re: GWTFeedReader broken ?

My final update on this topic. Just discovered an alternative which
compiles and runs without problem.
I'll use that in my project instead of GWT-Feed-Reader.

Re: different behavior on chrome and firefox

[Vik]

Hie

Yes i m using onBlur.

Right I have same opinion that window alert is too bad.
What I want actually is just marking the component in red and showing a
message somewhere near the component. How can i use a popup below a textbox?
I mean i guess popup comes also like a window only ?
Is there any available example to follow as it will take me good time to do
it all.

Re: GWTFeedReader broken ?

[Henchan]

Spoke too soon. Actually, the 1.4 branch has exactly the same problems
as Trunk.
I am not familiar with ant, so my problem might lie in the way I am
bringing the project in to Eclipse. However, I suspect it is just
because it's a very old code base which no longer works against a
contemporary SDK.

Has anybody else recently compiled this project successfully ?

GDBE - Build a custom Google Docs Editor

[Bobby]

GDBE is an open source project providing a basic text editor for
Google Docs:
http://code.google.com/p/gdbe/

You can check out the live version here:
http://gdocs-base-editor.appspot.com/

It's built with GWT and the AppEngine, just upload to your AppEngine
account and you'll have a working editor.

We can use GDBE to build customized document editors, for example:
http://docs.latexlab.org

If you're interested, check out the source and make it your own. :)

Enjoy

Bobby

Output of two entrypoints overlapping

[Blessed Geek]

I have an entrypoint module Main.

I have another entrypoint module User

User inherits non-entrypoint module UserPersistence.

At some time, I inadvertently had module UserPersistence inherit Main.
That is, User module effectively inherits Main.

The result was, when module User is displayed, it was overlaid by the
output of Main. It took sometime to search for it and finally the
problem of module overlap was solved when I removed the inheritance of
Main in UserPersistence's gwt.xml.

Therefore, is it safe to say that you can create a mashed display of
entrypoints by having a module inherit those various entrypoint. That
inheriting an entrypoint would result in that entrypoint module's
content overlaying the current entrypoint's outuput?

Is it safe to say that this is a feature I could exploit rather than a
bug? Is there any documentation on this feature or is it a feature I
have to either discover incidentally or by logical deduction.

What are the precautions that I need to take when making use of such
method of module overlay?

I had always thought that "inherits" was akin to "import" - no runtime
effect if not used. But it now seems "inherits" is more like
inclusion.

Re: Eclipse JavaEE tools + GWT Development mode

[ekr]

Hi Keith,

I played and played with Eclipse build path order etc. to see if I
could get the GWT plugin to use the JDK parser, not the one from the
J2EE app server OC4J. No Luck. Not sure what is driving this.

I looked at the source code In the dev subproject
com.google.gwt.dev.util.xml.ReflectiveParser.java
and found that it sets the feature 
http://apache.org/xml/features/nonvalidating/load-external-dtd
to false.

>From http://xerces.apache.org/xerces-j/features.html

http://apache.org/xml/features/nonvalidating/load-external-dtd
True:   Load the external DTD.
False:  Ignore the external DTD completely.
Default:true
Note:   This feature is always on when validation is on.

Not sure what the JAXP spec says but the code here is assuming (I
think) a Apache (xerses) parser which in this case
may not be a good assumption. Perhaps the ReflectiveParser should
catch this exception explicitly
"org.xml.sax.SAXNotRecognizedException" and log it or something. Not
sure if the Oracle impl should ignore features that it doesn't
understand but we have no control over that. Anyway, hopefully this
can be fixed and until then ...

Workaround for GWT compile for OC4J
Advanced->VM arguments
-
Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl

Thanks for the pointers - gave me some motivation to dig deeper,
Eric

Re: GWTFeedReader broken ?

[Henchan]

Thanks for your advice. No doubt gwt-feed-reader is old code. I'd
happily switch to another implementation if especially if it supports
more recent updates to the Feed API. The only alternative I've found
depends on extjs, which I am not using elsewhere in my project.

Anyway as you indicated... 1.4 resolves the errors. Cheers!

Re: Creating images with sources outside of the webapp context.

[Erick Audet]

You can try to create a symbolic link (ln -s) or a windows shortcut of your
images located outside the web context. Create these links inside your web
context. Your photoPath must be relative to you web context.

Ex.:
(out of the web context): /home/myhome/images/toto.jpg
(in the web context): {context root}/images/toto.jpg (ln -s or windows
shortcut)

Compound properties

[b.thakker]

Hello

We have several modules with 168 permutations each due to 6 browsers,
7 languages, 2 log-level modes (fatal and off) and 2 stack-trace-
emulation modes (6*7*2*2 = 168). The entire app takes almost 5 hours
to compile.

This makes me ask whether its possible to have compound properties in
GWT?

For example, I need stack-trace emulation only when log_level is set
to true. This will help me reduce the number of permutations to half.

Instead of the log_level/stack-trace-emulation combinations of
FATAL/TRUE, FATAL/FALSE, OFF/TRUE, OFF/FALSE

I get FATAL/TRUE, OFF/FALSE.

Please let me know if that did not make sense or if I'm missing
something.

I will highly appreciate any insight.

Thank You.

Creating images with sources outside of the webapp context.

[Vince]

Hello,

I'm trying to create an image with a source on the server located by
an absolute path, e.g.

...
Element imgElement = DOM.createImg();
imgElement.setAttribute("src", photoPath);
Image photo = Image.wrap(imgElement);
vp.add(photo);
...

where in, vp is a VerticalPanel widget and photoPath is the absolute
location of the image from the server's local folders, e.g. c:/folder1/
folder2/filename.jpg. NOTE : The images do exist.

It doesn't seem to do the trick as I am getting that funky colorful
browser icon on it's expected place on page.

Is there a correct way of doing this? Would appreciate any leads I
could follow...

Thanks,
Vince

Re: GWTFeedReader broken ?

Hmm ... from its how to build:
"

Maybe this is why you get the errors?

Re: Extra HTML in response from

[kozura]

Dunno what the problem is, probably would just make sure the code
ignores any extra junk vs worry too much.  But as an aside I'd highly
recommend the gwt-upload package for this sort of thing, esp. images
that can be sizable.  It takes care of all this, including getting you
back a unique id, and gives the user a nice downloading progress bar,
with minimal code needed.

Re: different behavior on chrome and firefox

[kozura]

What event are you using for activating your validation?  onBlur?

As for the second question, you have the full power of Java OO
programming available.  So either extend TextBox, or make a Composite
widget containing a textbox, that encapsulates what you want, maybe
ValidatingTextBox.  Give it a mechanism for generically validating,
maybe a callback class or whatever, and based on the result add your
coloring/popups/etc.  Then instantiate it for each field, with each
particular validating callback.  BTW I'd avoid alert as it locks your
browser, requires an extra user click, and isn't very pleasant; maybe
use a Popup below the textbox instead.

Extra HTML in response from

[Mark Butcher]

Hi all,

I'm having some issues with the FileUpload stuff. As far as I can see I'm
doing everything correctly and it works in everything except Chrome (in my
testing so far). What I want to achieve is to allow user's to upload an
image to our servlet - the servlet stores the image and returns an ID which
is then used in the GWT code to refer to that image from there on. This
basically works but on chrome I get the image ID and then some html (an
empty div tag). Here some code...

We set up the form:

final FormPanel form = new FormPanel();
String putUrl = UrlConstants.createPutImageUrl();
form.setAction(putUrl);
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);

VerticalPanel panel = new VerticalPanel();
form.setWidget(panel);

FileUpload upload = new FileUpload();
upload.setName("uploadFormElement");
panel.add(upload);

// Add a 'submit' button.
StyledButton submit = new StyledButton(constants.submitButton(), null,
"idod-button");
submit.addClickHandler(new ClickHandler(){
public void onClick(ClickEvent event) {
form.submit();
}
});
panel.add(submit);
popup.setClickHandler(new ClickHandler(){
public void onClick(ClickEvent event) {
popup.hide();
}
});
// Add an event handler to the form.
form.addSubmitCompleteHandler(new SubmitCompleteHandler() {
@Override
public void onSubmitComplete(SubmitCompleteEvent event) {
String results = event.getResults();
// here, on, chrome we get results == "89"
// where 89 is the id as expected and the result is unexpected
// we're trying to use the id as a number so we end up with a number format
exception
}
});


The relevant code from the servlet is:

protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
try {
   // snip :)
resp.setContentType("text/html");
ServletOutputStream outputStream = resp.getOutputStream();
outputStream.print(Long.toString(id));
} catch (Exception e) {
responseError(resp, e.getLocalizedMessage());
}
}

I've tried closing the outputStream and calling resp.flushBuffer() to try to
make sure that nothing extra is written to the stream but it makes no
difference, and, in fact, I'm pretty sure that the servlet is returning the
correct information and that it is getting messed up in the browser somehow
(epecially as it appears to be browser specific). I've very inelegantly
worked around the issue by splitting the number of the front with a regex -
this works but I'd like to know why it is necessary and if there is
something nicer I can do to make things work.

Any ideas very much welcome.

cheers,

-mark

different behavior on chrome and firefox

[Vik]

Hie

Please have a look at:
http://1.latest.sakshumweb20.appspot.com/ui/page/DonorRegister.jsp

Click on
the first name field. and then tab out without entering anything.
In firefox the field background becomes red but it does not happen in
chrome.

Any reasons why the difference in behavior? and how to fix it?

One more thing right now i am showing the error message as a window alert.
Is there a generic way to mark the component in red and show a error near to
it?
Programmatically doing it will be a lot of effort for all the ui components.

Re: Stockwatcher - JSON PHP variant

[Marcello Nuccio]

Hi Bill,
I am using a similar setup and it works for me. I have described my
procedure in a previous post (I hope to get a working link...):
http://groups.google.com/group/google-web-toolkit/tree/browse_frm/thread/a60c42b29bbce71f/5b083ddda237e2e0?rnum=1#doc_d5da39ec906f4353

The only difference is I am on Linux (Ubuntu 9.10), but I do not think
it should make any difference.

I am using PHP Data Objects (PDO) with MySQL driver to access DB.

I post my PHP script here as an example. This simply return a custom
json file with data from a SQL query. I retrieve it via Restlet-GWT
client.

   true
));

echo '{"columns":', json_encode($columns), ',"rows":[';
foreach($dbh->query('SELECT * FROM Plants') as $row) {
  $plant = array();
  foreach ($columns as $column) {
$plant[] = $row[$column];
  }
  echo json_encode($plant), ',';
}
echo ']}';
  } catch (PDOException $e) {
header("HTTP/1.1 500 DB connection error");
exit;
  }
  $dbh = null;
  ?>

Checkstyle/PMD/FindBugs for GWT 2.0.3 projects

[Eric]

Has anyone configured any of the extant auditing tools for a GWT 2.0.3
project? For example, most tools declare the use of non-private non-
static instance variables to be errors, but @UiField instance
variables may not be private. Most tools mark declarations of concrete
collections as bad, but one should not use Map or List in GWT-
serializable code.

I would appreciate hearing from any of you who have configured
Checkstyle, PMD, Findbugs, or even static ApectJ @DeclareWarning
aspects for auditing GWT projects.

Respectfully,
Eric Jablow

Two way linking?

[flyingb...@gmail.com]

I am wondering if there is any way to do this.

I have a object that contains multiple values that the gui will show
multiple textboxes.

I would like to create a link between the textbox and values.

So if i edit the object value, the textbox will change and if I change
the textbox the object will change.

Is there a good way to do this?


also other textbox might be linked to same value so if I change the
value of the object both textbox change and if I change the textbox
value of either object the object value will change along with the
other textbox.

Re: How to download a JSON object from my GWT server?

[lineman78]

I would suggest using jersey services with a custom services context
resolver.  Put the following file in the same package as your jersey
services and replace **SerializableObject** with all of your root
elements.  Then check out the getting started guide on
jersey.dev.java.net

@Provider
public abstract class ServicesContextResolver implements
ContextResolver
{
private JAXBContext jsonContext;
private static final Class[] types =
{**SerializableObject**.class};

public ServicesContextResolver()
{
try
{
jsonContext = new
JSONJAXBContext(JSONConfiguration.natural().build(), types);
}
catch (JAXBException e)
{
e.printStackTrace();
}
}

@Override
public JAXBContext getContext(Class objectType)
{
return jsonContext();
}
}

Question about GWT module file

[Ehsan]

Hi, I've a big GWT module which comprised of many java classes (& of
course it's impossible to break it down into several modules).
My GWT application consists of some forms, but the users usually work
only with a few of them, anyway they should be abale to open any form
as they need.
Now my problem its that gwt generates a big js file that will load
each time, but most of its content may never use!
Is there any way to break the big js module file into several smaller
files(for example, one file for each class) & gwt load them
automatically as needed ?

Re: Google's new "Making AJAX Crawable Spec" - Question/Problem re: Sitemaps

Hi Katharina,

Thanks for the update. When you say "please me sure to make a change
to your
Sitemap", do you mean minor changes such as adding / removing a URL
will suffice or should the last modified date for every URL in the
sitemap be updated?

Thanks,

Re: How to put same widget under multiple tabs in TabLayoutPanel?

[euzuro]

I think the way to do what you want to do is to use a separate
TabBar[1] and DeckPanel[2]

I haven't done it myself, but I know that the TabLayoutPanel (and
TabPanel) are both composed
of these two objects. The TabBar is the actual set of tabs, and the
DeckPanel is the set of
widgets that get switched. Basically, I think what you'll have to do
is just rewire them together,
shouldn't be too tough.

No. GWT just takes your class's full name and appends
_CustomFieldSerializer to it.

Everything in the java.* package is special-cased and prepended
"com.google.gwt.user.client.rpc.core." (in addition to the
_CustomFieldSerializer suffix).

Re: button click event not firing

[kozura]

The events don't get hooked up if you use something like setInnerHTML
to add them, you have to use the GWT add methods.  So you should be
using something like body.add(hPanel).

Re: A question!

[Joel Webber]

[+gwt group]

Konark,

I actually don't see an attached screenshot (perhaps you forgot the
attachment -- I do that all the time). I would normally recommend just
looking at the Showcase source (it's part of the GWT distribution, and you
can find it online here:
http://code.google.com/p/google-web-toolkit/source/browse/#svn/trunk/samples/showcase).
If you have questions about specifics, please feel free to ask them here on
the group, and I may be able to help as well.

Cheers,
joel.

custom serialization

[mmoossen]

dear all!

i am using a legacy class with gwt.
first i got it working on the client using super-source :)
but then serialization was not working so i had to write a
CustomFieldSerializer which is actually also working :)

i have now only one question: is there any way to have the serializer
class in a different package than the class to serialize? may be with
an annotation or an additional interface in the class?
(it has to be something like that, if i see where the serializers for
Integer and co. are located... but i could not figure it out...)

thanks
Michael

JS problem on Firefox

[Šobis]

Hi,

I have a problem with JS in one of my GWT projects.

I have a JS in my HTML file. In this JS I have a register function,
which I call later in project.

Problem is, that sometimes in FF when I call register function I get
function is undefined message. I NEVER get this message in Chrome,
only in FF.

Any idea what could be reason for that? Main problem is, that this
doesn't happen every time, sometimes it is ok. It looks like JS, which
is executev in HTML file breaks. Why can this happen? Can I reexecute
this JS?

Tnx for any help.

Matej

Re: Irony: GWT Showcase demo does not work with Chrome

[Michael]

I see the same with latest 5.0.371.0 on OSX.

But after opening the Developer Tools, the showcase is working - it
even remembered all the clicks I made before!

Re: Working with serial ports

[rudolf michael]

you can make a java applet, or swf component to have access on client side
ports then i guess applets/swf can easily communicate with javascript which
you will write using GWT.

Working with serial ports

[theBULLL]

Hello,

I am trying to accomplish the following...

I want one client, running on a PC,  to send messages to a server,
running on Google's server, and then have the server relay the
messages to another PC.  Ultimately, I would like to ship the messages
out the serial port of the second PC.  If I understand correctly, this
cannot happen with JavaScript because of obvious security problems.  I
was wondering if anybody had any suggestions on how I can either work
with GWT or write another java app to run on the second PC to retrieve
the messages from the browser running the JavaScript.

I realize they may be confusing an hard to read so please let me know
if further information is required.

Thanks,
theBULLL

Serial Port Access

[Johnyo]

We would like to develop an application that can be used to remotely
control a small vehicle using GWT. In order to do this, we need a way
for our program running on a google server (using GWT) to access a
serial / usb port on a client computer to send radio commands to the
vehicle.

Is this possible? Is it possible to access a serial/usb port on a
client computer from a GWT project running on a google server, and
then send/receive that information? And if so, can you point me in the
direction of a solution?

Thank you for any response.

Resizing DockLayoutPanel child.

[dueckes]

Hi all,

I have a DockLayoutPanel with two children, one occupying the West
Direction and the other Center.

When a user clicks a button my intention is to resize the child in the
West direction and have that stretch or shrink the size of the child
at the Center direction accordingly.

Playing with the API I have been able to achieve two things:
1) Resize the _entire_ DockLayoutPanel via a callback passed to the
animate method.  I don't seem to be able to manipulate child
dimensions here.
2) Using a similar approach, resize the child in the West Direction
_without_ effecting the dimensions of the child at the Center
Direction - i.e. the DockLayoutPanel containers for the children are
uneffected.

I have considered subclassing DockLayoutPanel and exposing a method to
manipulate child widget LayoutData directly - but this approach
doesn't play well with UiBinder.

Can anyone recommend any way of achieving this?  Note I'm also
experiencing a similar problem with SplitLayoutPanel.

Regards,

Matthew

GWTFeedReader broken ?

[Henchan]

I downloaded GWTFeedReader from http://gwt-feed-reader.googlecode.com/svn/trunk
into Eclipse (via SVN) for the first time. The GWT 2.0.3 SDK is
installed and other projects are compiling fine.
Eclipse highlights  a small number of errors in the GWTFeedReader
source.
The first: "StyleInjector cannot be resolved". There was no class
called StyleInjector in the svn repository. Though I could find the
source through the web interface
http://code.google.com/p/gwt-feed-reader/source/browse/trunk/src/com/google/gwt/sample/feedreader/client/StyleInjector.java?r=36

Installing just this class did not resolve the problems, however.
Suspecting that the svn package's integrity is compromised, I am
reluctant pursue these errors piecemeal.
Or maybe I am just doing something wrong ?

How to download a JSON object from my GWT server?

[Sherry]

Hi,
I would like to have my application return a JSON object for
download.

I'm trying to simulate the behavior that happens when I access the
page: "http://search.twitter.com/trends/current.json?exclude=hashtags";
in which the Chrome browser automatically downloads a file
current.json . I've tried to print the JSON string into the output or
through a JSP but it doesn't work (I need to return this JSON file
into an XMLHttpRequest object).

I've copied the current.json file I downloaded from the twitter link
above into my WAR folder, but when I access it through Chrome it just
opens its contents in the browser, and I would like to be able to
download it, as in the twitter link.
Can anyone direct me how to force this download to happen?
Thank you
Sherry.

GWT calendar

[Naveen]

Hi

I need to implement calendar functionality to an already existing non
GWT project. I would like to know if it is possible to integrate the
GWT calendar to my non GWT project. I am aware that we need to convert
the java code into java script, so my question is can i run this as an
separate GWT project and then implement that java script in my
project.. Plz let me know if this will work also any other info will
be of great help..

Re: Ant Build.xml

[nava nee krish]

Hi,

make sure that the error you got because of classpath issues. If so then add
classpath entries in your build.xml.
In eclipse the classes are available regardless of build.xml classpath
entry. But outside eclipse you need explicitly specify the classpath
location.
If you could attach the error trace, then we can help.

Nav

Re: Compiled JS more readable?

[Henrique Viecili]

Are you talking about GWT 2.0 or previous versions? Last time I tried
to use the -style property in GWT 2.0 I got an error message in
compilation time telling me this:

Unknown argument: -style
Google Web Toolkit 2.0.0
DevMode [-noserver] [-port port-number | "auto"] [-whitelist whitelist-

level] [-gen dir] [-codeServerPort port-number | "auto"] [-server
servletContainerLauncher] [-startupUrl url] [-war dir] [-extra dir] [-
workDir dir] module[s]

And I've done a little search in the forums and it seems this property
was removed from GWT 2.0... unfortunately.

Re: GWT and JAAS

For sure, but to do this you'll need a JAASRealm (or something like that)
and to secure the hosted page or the whole site.
If you want to perform authentication and security  at a service level
(GWT-RPC) spring integration will ease the process at least at my POV ;)
