GWT performance

[kristian]

Hello All, i am a newbie that want to try to build a web application
using GWT, but i heard from some of my colleague that GWT has some
issue with its performance (reliability, load slowly). So, is there
anyone can enlighten me? Thanks.

Re: New Windows Update Causing Hosted Mode Failure - GWT 1.5

[DuoCentillion]

Nevermind.  After a proper reset, it works fine again.  Half installed
Windows Updates can be fatal to GWT I guess.

Re: Accessing CouchDB from GWT using JCouchDB library

[Arthur Kalmenson]

Why don't you do the processing on the server side? Just make an RPC
to the server and let it do the heavy lifting in communicating with
CouchDB.

Re: Catching Hyperlinks before they are executed.

[Chris Bailey]

OK here is the soluction I came up with:

Event.addNativePreviewHandler(new Event.NativePreviewHandler() {
@Override
public void onPreviewNativeEvent(NativePreviewEvent 
event) {
if (event.getTypeInt() == Event.ONCLICK) {


// do something with the keycode
// 
doSomething(event.getNativeEvent().getKeyCode());


if(com.google.gwt.dom.client.Element.is(event.getNativeEvent
().getEventTarget())){
Element targetElement = 
(Element) Element.as(event.getNativeEvent
().getEventTarget());

if("a".equalsIgnoreCase(getTagName(targetElement))) {
//String hostURL = 
GWT.getHostPageBaseURL();

String href = 
DOM.getElementAttribute
((com.google.gwt.user.client.Element) targetElement, "href");

//
check href against hostURL to see if the link is realitive or absolute
then do whatever you want.
//event.cancel();
}
}
}
}
});

native String getTagName(Element element)

Re: linux & servers

[bcw]

To answer your last question first, I want to learn.

I write Java at work.  I've done SOA and Swing.  The world is moving
to Web 2 (or already has) and I want to as well.

So, I want a project that gets me into that heavily.  With Google OS
coming, I see the browser reinforced as the place to be.  It already
can host all the multimedia capability I could want, and I don't have
to assemble it on top of my own custom framework - I just have to
learn to use it.  Why reinvent the wheel another time?

I have a system library that does a simple computation.  I send it a
string, and it returns a computed string.  That provide a good basis
for figuring out how to deal with the issue of getting local
facilities (such as Octave, Macsyma, or legacy AutoCAD running in
WINE) into the browser space.

Some local programs provide server solutions, and some don't.  I'm
looking at a simple example that doesn't, to learn how to deal with
that.

I have the thought that a FireFox plug-in might allow access.  I'll
want to learn about the security issues along the way.

The other approach I've seen is RPC, which means a local server, which
leads to the 'server collision' question.  One well-meaning response
I've received suggested forcing a Tomcat install and assigning a
'random port'.  That doesn't mean there won't be a collision -
everyone is going to be doing this in the near future.  I was hoping a
more definitive approach had been worked out by now...

I don't agree.  GWT still allows me to write OO architecture, gives me
easy access to layout facilities, etc.  The browser itself gives me
substantial support for multimedia and plugins for different data
formats.

Unless I don't understand something...?


Ultimately, I'm writing a PIM (Personal Information Manager) that
leverages all the online applications, since we're living our lives on-
line.  But I also want to be able to access selected local computing
resources that a user may have invested in.  Some people want to drag-
and-drop statistical analysis streams their colleagues have published
into their own PIM - and have them passed through their locally-
assembled analysis tools for processing.

Yes, it can be done unsafely.  Can it be done safely?  How do I do
that?

This first very simple example will get me started on learning and
building.

Thanks for the information.  I would welcome any more pointers,
thoughts, search phrases I haven't thought of yet, etc.

Cheers,
bcw

Re: mocking HasWidgets interface

[Davis Ford]

Hi Thomas -- my test is a pure JUnit test -- now a GwtUnitTest.

HasWidgets is an interface -- so the piece I am missing is how/why
EasyMock.createMock(HasWidgets.class) can somehow be instantiating
GWT.create() ?  I checked and double-checked the package namespace,
and it is definitely referencing an interface.

I never call GWT.create( ) in any of the code I am testing or the test
code itself.

To work around this, I just did this:

public MockHasWidgets implements HasWidgets {

   etc...
}

and use new MockHasWidgets() in my test cases.

Re: GWTTestCase not running?

None of the test methods get called, I'm sysout'ing everywhere and stepping
it through a debugger, it isn't being run at all.  And I notice the output
never says it gets run, only compiled.

Can you give me an example of one of your GWTTestCase's ?

Ah...  For all I know, GWT has some facility to support this.  It was
worth asking to find out.  As well, there might be some other approach
or work-around to support this, and I'd want to know about the
interactions between that approach and GWT.  It wasn't obvious from

I haven't read everything yet, but I haven't seen anything to suggest
this.  Instead, I've read the suggestion to use RPC, thus leading to
the 'server collision' questions.

Can you point me at a resource that talks about calling shared local
system libraries (libCompute.so) from FireFox JavaScript?

If this is what you are referring to, I can read about that.  I
haven't seen anything addressing that a local script could call a
local system library so much, but I am just starting to think about
how to do this.

If you can point to a resource that speaks to having local javascript
access local system-level shared libraries, that would save me some
time.  Google hasn't come up with anything yet, but perhaps I don't
know the correct terms to use.

Try el.cast().getValue() instead; getNodeValue() is a
"generic" DOM method that cannot be aware of the ".value" property
specific to InputElement's.

Is it possible to programmatically open a submenu?

[Michael Sullivan]

So I posted earlier about events to detect when a submenu opens or
closes - I as able to override onLoad and onDetach to do that.

I'm using GWT dnd to drag stuff onto a menu Item. I'd like to have
submenus open automatically when I mouse over them, but the existing
event seems to get consumed by my drag/drop handlers.

Is there any way I can just call an 'open' type method on my menu item
to open its submenu? I've looked through the source code and the only
way to trigger this seems to be through onBrowserEvent, and I'm not
entirely sure how to fudge that.

Am I the only one who'd like a little more accessibility to classes
like MenuBar?  It seems package private and private were used far too
much in its methods.

Re: DOM.getElementById() vs $doc.getElementById()

[Thad]

Using Document.get().getElementById() returns an element, but it has
no value:

Element el = Document.get().getElementById("username");
if (el != null)
GWT.log("element: "+el.getNodeValue(), null);

prints only "element: " in the console.

Something like the following? ;-)

Re: date incompatibility between GWT java.util.Date class and the javascript Date

[costa]

Nobody there? Should I fill in a bug report? As it is right now I
don't think using java.util.Date to pass dates to a remote service is
reliable in the web mode and there can be very subtle bugs that are
hard to track.

EasyMock is only usable in pure Java, i.e. (to make it short) not in a
GWTTestCase. If your code ultimately depends on GWT.create() (which
EasyMock does not!), you can use GWTMockUtilities to make GWT.create()
work (and simply return null).

In a word, your GWT.create() issue is unrelated to the EasyMock line
you quoted.

Re: WYSIWYG version of Google Plugin for Eclipse coming soon?

[Andrew B]

Hi Keith,

We don't have any immediate plans to release WYSIWYG tools for GWT or
in the Google Plugin for Eclipse. We have ideas about helpful tools,
but right now those are just that - ideas. I've heard good things
about GWT Designer, though I've never used it extensively myself.

troubles with setAccessKey in Firefox

[Marcão]

Hi

I'm trying to set an access key to a button widget like this:

Button b = new Button("Insert");
b.setAccessKey('I');

b.addClicklistener(new ClickListener(){
public void onClick(Widget sender){
 Window.alert("bla");
}

});

So, when i press Alt+I (In Firefox 3.5.2) , nothing happens.

Anyone can help.
Thanks.

Re: Catching Hyperlinks before they are executed

[ThomasWrobel]

I'm not sure thats possible at all. You might have to make gwt link
objects that look like normal hrefs and replace all of the ones in the
page with these.
I had to do this myself for my project. (but for a different reason, I
needed bookmark links to work in frames...IE had some bugs that meant
I needed to use gwt links instead).

[gwt-incubator] GWTCanvas and IE...

[Xlorep DarkHelm]

Ok I'm hitting a roadblock here, and I'm hoping that it is just
something obvious that I'm unable to see.

My situation is this -- I'm working on a simple web app, using GWT and
the GWTCanvas widget from gwt-incubator.

With the canvas, I am trying to draw little black squares, which
represent values at a specific position in an array.

To me, it is pretty straight-forward, I have a method:

-

public void draw(int row, int col, int color) {
canvas.setFillStyle(Settings.colors[color]);
canvas.fillRect(col * Settings.PIXEL_SIZE, row *
Settings.PIXEL_SIZE, Settings.PIXEL_SIZE, Settings.PIXEL_SIZE);
}

-

in my class that wraps the canvas. On every major browser other than
IE (and I can only test with IE8... which might make a difference, I
dunno...), this works exactly as I'd expect.

In IE... it never draws anything. Like... at all. I see that my code
is running (I have some text which gets updated outside the canvas),
but IE isn't drawing, well... anything. This somewhat leaves my little
app as pretty useless for people who visit using IE.

Like I said... I'm hoping that it is something I'm just plain missing
here. The address to my app is:

http://showsort.appspot.com

I'm not really trying anything elaborate with the canvas in this...
just drawing some squares on it.

Any help would be most appreciated.

I can provide other code if it helps...

GWT serialisation too slow

[David Given]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I've got an app intended to run on a fairly low-end server, so I've been
optimising it as hard as possible.

Right now I've got it to the stage where the biggest bottleneck is the
GWT server-side serialisation, as it's squirting a large database sync
over to the client. My app is taking about 300ms to run the business
logic, 2000ms to construct the delta... and a staggering 20 *seconds* to
serialise it before sending it to the client. (Numbers approximate as I
can't insert any instrumentation into the GWT backend.)

The packet's not very big; 20kB compressed on the wire, as far as I can
tell, and about 500-600 objects.

Does anyone have any suggestions as to how I can speed this up? Right
now the time it takes is unacceptable. Can any alternative serialisation
system be plugged in, for example?

The short answer is no.

The longer answer is probably not. Most web browsers provide some
feature where Javascript can call out to host services; for very good
security reasons this is disabled most of the time. Most of Firefox, for
example, is written in Javascript using these services. How precisely to
get at these functions varies from browser to browser.

The even longer answer is maybe, provided you're willing to use some
third-party technology to provide the interface between Javascript and
the system functions. For example, a Java applet, Flash plugin, Firefox
extension, ActiveX control... of course, doing it this way rather
negates any advantage to using GWT.

[...]
> Is there a "server registry" to deal with such contention?

The short answer is no. (Don't hit me.)

The longer answer is sometimes. Debian and Ubuntu Linux, for example,
provide infrastructure so you can just install a server --- any server
- --- and drop a CGI script into /usr/lib/cgi-bin and it'll just work. Red
Hat is probably different. Windows doesn't have anything like this. OSX?
No idea.

Sorry I couldn't be more helpful. What precisely are you trying to do?
What host functionality do you need?

DOM.getElementById() vs $doc.getElementById()

[Thad]

Why does DOM.getElementById() return null while $doc.getElementById()
in a JNSI method return a value?

I'm trying to add a logon form to my welcom-file HTML (as mentioned in
http://code.google.com/p/google-web-toolkit-incubator/wiki/LoginSecurityFAQ).
The username looks like
, and is
A.  The invoking button is written in GWT so that it may call my
logon RPC.  My application is loaded in B.

In the button's ClickHandler, if I request
String name = DOM.getElementById("username").getNodeValue(), the
element is null, not found.  However if I request tring name =
getUsername(); where getUsername() is
private native String getUsername()  /*-{
 return $doc.getElementById('username').value;
}-*/;
the value of the username field is returned.

Why is the document different from one to the other?  Can I get the
username without JNSI?

Basically, it uses one or two native javascripts functions, the rest

Re: Problem on loading several times the same image

Sure :


public static void placerImage(final String urlImage, final

final Image img = new Image(urlImage.toString());
cPanel.add(img, 0, 0);
// Resizing after load
img.addLoadHandler(new LoadHandler() {
@Override
public void onLoad(final LoadEvent event) {
// Remove image
cPanel.remove(img);

// Smaller image
final float rapport = 2;
final int x = (int) (img.getWidth() / rapport);
final int y = (int) (img.getHeight() / rapport);

if (x > 0 && y > 0) {
img.setPixelSize(x, y);
}

// Center image on the panel
int left;
int top;
int tmp = 
ConstController.getConstants().casePxSize() -
img.getWidth();
if (tmp > 1) {
left = tmp / 2;
} else {
left = 0;
}
tmp = 
ConstController.getConstants().casePxSize() - img.getHeight
();
if (tmp > 1) {
top = tmp / 2;
} else {
top = 0;
}

// add image resized
cPanel.add(img, left, top);
}
});
}


ClickablePanel is an AbsolutePanel with a mouseDownHandler.

Re: FileUpload

[Thad]

My application uploads a file at a time, but I make it work sort of
like a multiple upload.

My upload widget is inside a composite.  Once a file uploads, the
FileUpload is hidden, replaced by a checkbox with the name of the file
uploaded, and a new FileUpload widget is added to the UI.  The use can
upload more files, one at a time.  If a file name is unchecked, the
user is saying, "ignore this".

On the server side, I track the name of the files and the location of
the temporary files.  When the user finishes with the form, I send the
checked file names to the server with other data as a JSON string.
The list of checked files is compared with the temporary files, and
those listed are check into my system.  Other files are deleted.

mocking HasWidgets interface

...but if you execute this, it promptly throws:

java.lang.UnsupportedOperationException: ERROR: GWT.create() is only
usable in client code!  It cannot be called, for example, from server

This usually happens when you execute any code in standard JUnit tests

Re: FileUpload

[Jason Essington]

libraries like commons-upload allow you to iterate each form element  
whether file or input or whatnot, so just iterate until you've got all  
the files.

Showcase Sample

[Eric Atkinson]

It would be nice if you created a middle-complexity sample app, and
related section in the developer's guide, that's a cross between the
too-simple mail-sample and the too-complex showcase-sample.  Why?
Because the main thing I suspect that developers want to know --
somewhat quickly -- is how to create a "navigable" user interface that
actually does something but isn't overly complex. For example, the
mail app shows a menu tree that doesn't actually do anything while the
showcase app has a menu tree that does plenty but is so complex in its
implementation (generators, constants, etc) that it would take a month
of code review just to figure out exactly how the showcase sample
works before a "new" gwt developer could use it as the basis for doing
something themselves.  I imagine you wish to instill good coding
practices in your external developers which I why I suspect the
showcase sample is so complex, but going from the too-simple mail
sample to the too-complex showcase sample it too much of a jump
conceptually speaking, especially without a complete explanation in
the developer guide similar to the "getting started" tutorial (which
is also too simple and non-navigable).  Don't get me wrong, your
developer's guide, and related sample apps, are excellent and far
above what any typical open source project provides in terms of
documentation and samples, but a better explanation of the showcase
sample, in particular, is needed I think (even though the code
comments are also very good). Consequently, I've come to conclusion
that this additional documentation of the showcase sample, as a
"getting started" guide, is something I could do for you (the google
gwt team) in return for your very fine work to-date; however, if you
happen to have such a "getting started" guide for the showcase sample
app somewhat in the works already, then I would appreciate your giving
me access to it, such as sharing it me in my google docs interface at
username: atki4564 (or just mailing me what you got so far). Many
thanks for your time and consideration.

How to get user current location in google maps

[bala]

Hi There,

  Im a beginer with google maps, and im trying to use google maps with
gwt. i have few question which im trying to
  understand here

1. in the examples i observed maps being displayed based on longitude
and latitude but im wondering is there a way
that i can the user location automatically like when every i use
google maps in my mobile i automatically get my
current location. is there any such feature available?

2. is there a way that i can get the location details using when user
clicks on a location in the map and can i store
them in my database so i can use those later when user comes back

3. what is the scalability of using google maps like if i have 1
user online in my website at any given 15 min
interval. would google accept all those requests? or are there any
limitations for such usage


Any help on the above would be appreciated.

Thank you,
bala.

There is no entry in it for today.
The old install is also 3.4.0 SDK

Well, none of these questions are really GWT-related. Any further
discussion of this topic should be done off-list.

One's an operating system, the other's an architecture; you might want
to address that dichotomy in your problem statement.

You can call shared libraries from Firefox JavaScript. I don't know
about Chrome.

Firefox will load an html file from a local source (via the file://
protocol); which file can reference and execute local scripts.

I can't speak to the Mac OS implementation, but most (if not all) Linux
distros incorporate a package management system; which software allows
the package implementer to declare dependencies on other packages. The
declaration is then processed by the package manager. You can use this
to incorporate your package's dependency on an HTTP daemon.

Re: Repeating http requests

[Adligo]

Hi All,

   This is my quick hack that fixes that issue;
http://yourserver/yourPath?yourCgiParams=yourValues&request=1
http://yourserver/yourPath?yourCgiParams=yourValues&request=2
http://yourserver/yourPath?yourCgiParams=yourValues&request=3
exc

Also note this can be applied to html and property files (or any
files)
http://yourserver/funky.html&request=1
http://yourserver/drummer.properties&request=2

I have been using a static int counter to accomplish this trick.
I think GWT should add some caching options to its http api, because
this is quite hoaky.

Cheers,
Scott

Re: onMouseOut not always caught

[Alexander Cherednichenko]

I had same problems - mouseOut events were missing in IE.
I believe, these are not GWT problems, browser does not simply produce
appropriate event.


I then had to implement EventPreviewer, and listen to all mouseMove
events (well, it was performance-satisfactory). On each get of
mouseMove event i was checking if target element is the one I'm
listening to, and if not, treated this as mouseOut. Several tips:
  * Start eventPreviewer only when you get mouseOver event from your
icon. This would save some ticks.
  * If you're waiting for mouseOut of complex element, beware not to
forget to check the element as DOM.isOrHasChild(el, mouseOutEl)
  * be sure to disable event preview once you got synthetic mouseOut.
This would help save ticks as well.

gwt-connectors - arrowed lines on diagrams

[Robert Waszkowski]

Hello,
As far as many people were asking about ending connector lines with
arrows I made a new version of the library that can do that.
Gwt-connectors v. 1.7 now supports GWT 1.7 and gwt-dnd 2.6.5.
Except arrows you can split connector for as many sections as you
want.

Any sugestions about connectors behavior and further development will
be appreciated :)

Robert

Re: Eclypse plugin not working in Eclipse 3.4

[Miguel Méndez]

In the .metadata directory there is usually a file whose name is literally
".log".  If that does not exist then there is some other problem with your
install.  Without a log file I can't really determine what is going on with
your install.
So you are using eclipse 3.4.0, but what flavor of eclipse :)   Is it the
Java developer's version, the RPC version, the classic version?  You
normally determine this when selecting which download to use.

It might be a good idea to download a new version of Eclipse 3.5 for Java
Developers and try to do a fresh install of the plugin for Eclipse 3.5 into
it.  You can get Eclipse 3.5 installs from http://www.eclipse.org/downloads/

linux & servers

[bcw]

Hello,

I'm designing an app that will use a browser (FireFox or Chrome when
it's available) to provide the UI, and GWT for the development, but it
won't be connecting to a remote server - it will serve personal data
off the user's own system.

I'm targeting Linux (which I run) and maybe the Mac.

Those browsers run javascript without help, but I also want to be able
to access some shared system library functions on my linux box for
computations.

Is there a way to do that from a browser without an intervening
server?


If not (or if I find other reasons I need a server) there is a second
layer...

What if the user has already installed an application that has pulled
in a server?

I notice there are documentation systems that use one, and they might
have installed Tomcat, Apache, whatever... how do I tell?  how do I
integrate the components I use to provide my required services with
their server - including when they aren't server-aware and don't even
know they've installed one?

Is there a "server registry" to deal with such contention?

thanks in advance,
bcw

@RemoteServiceRelativePath

[Aximilli302]

Me again, I have another quick question for the general comunity.

What goes into the @RemoteServiceRelativePath tag? Is it the name of
the class it is in? for example,

package com.google.tabs.client;

import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
@RemoteServiceRelativePath("MyService")

public interface MyService extends RemoteService{

public String myMethod(String s, String username);
}



I put that in, and the server call fails. I get a warning:

Sep 1, 2009 9:24:28 AM
com.google.appengine.tools.development.LocalResourceFileServlet doGet
WARNING: No file found for: /tabs/MyService

Re: Eclypse plugin not working in Eclipse 3.4

[Miguel Méndez]

It does appear that the plugin did not install correctly.  Are you sure that
you used the right version of the plugin for your version of eclipse?
If you are sure, could you add an issue to the GWT issue
trackerand
include your eclipse .log file (the .log file should be in your
WORKSPACE_DIR/.metadata.log)?  Please respond back with the issue number and
we'll look at it.

Having the log file might help us understand what is going on.

they do not appear.

There is no Google in that list.

All I can see in installed software tab, that Google Plugin for
Eclipse 3.4 is installed.

Is there no toolbar an icon for New Web Application Project?  Is there no
New Web Application Project item in the File > New menu?

Could you try Window > Reset Perspective to see if the items above appear?

Usually this happens when there is a problem with the project's SDK.  What
SDK is the project using?  You can check the status of that SDK by
navigating to Preferences > Google > Web Toolkit.  See if the referenced SDK
appears in the list of SDKs and that there are no red X's associated with
it's icon.  If there are, select the SDK and its problem will be shown in
the message area at the top of the dialog.

Eclypse plugin not working in Eclipse 3.4

[aftershock]

I am on Windows 7 and I use 1.7 version.
I use Eclypse 3.4 and I install Eclypse plugin using software updates.
It installed ok but I can see it is not installed properly..

I cannot create a new web application because there is no such menu.
The project I created previously says import
com.google.gwt.core.client.EntryPoint; cannot be found... for example.
I cannot see the red gwt icon on which I could click.
SO all it seems as if nothing were installed.

So far I have tried these:
-tried to update gwt in Eclypse, no change.
-uninstalled gwt and installed ,no change.
-installed Eclypse 3.4 in another directory and installed gwt, no
change.
-I tried Eclypse 3.5 with new plugin, I could not install that, it
had
dependendency problem. It is another problem.
Note: this setup worked for me a month ago. I do not know what has
changed.
It is true I installed different kind of plugins for Eclypse but this
should not be relevant as I tried gwt with new Eclipse where the
other
plugin- I assumed - could not interfere as they did not exist.

Do you have a solution?

onMouseOut not always caught

[ToddP]

I have an app where, when I mouse over an icon I display a popup panel
containing additional information (similar to gmail's popping up info
when you hover above the "from" address in you inbox).  The problem I
have is that when using the onMouseOut, occasionally, the event gets
"lost" and the popup remains open.  Mousing over another icon results
in two popups then being open.

My questions are:

1)  is using onmouseover and onmouseout the best way to accomplish
this effect
2)  if so, how do I avoid leaving popups open due to missed onMouseOut
events

TIA

Re: Running Apache Hupa sample of GWT MVP

[Norman Maurer]

can you try to connect to it via telnet, just to see if there is a
firewall in front:

telnet imap.gmail.com 993
telnet smtp.gmail.com 465

Thx,
Norman

What I'm doing is:
 1. I'm not using any command line tool (including junitCreator)
 2. I have a "test" source folder in addition to my "src"
 3. I simply put my test classes in the same package as the classes
under test, just within "test" rather than "src"
 4. I do not have *Test.gwt.xml module; my GWTTestCase classes return
the name of the module being tested
 5. as for the JUnit dependency, I've just added the JUnit library
(project's Build Path -> Add library... -> JUnit)

You only need a *Test.gwt.xml module if you have to add some
configurations ( and the like) to your module under
test, or if you need some servlet (unit tests still use the deprecated
GWTShell, so they don't use your "war" folder and its web.xml, this
means you have to declare your servlets the "old way" using 
elements in your module's gwt.xml). Your *Test.gwt.xml in this case
would only  the module being tested and add the appropriate
 or other needed "configuration tweaks".

Thanks for the tip Matt. Though I feel the old (deprecated) way of
doing things was much clearer and easier to understand and code. I'm
not really sure why they changed it.

Re: onKeyDownPreview to onPreviewNativeEvent

[Mat Gessel]

What, you want to read properties from the Event? Absurd!

// (disclaimer: hand written in Gmail)
HanderRegistration reg = Event.addNativePreviewHandler(new
NativePreviewHandler()
{
  public void onPreviewNativeEvent(NativePreviewEvent event)
  {
Event event0 = Event.as(event.getNativeEvent());
if (event0.getTypeInt() == Event.ONKEYDOWN)
{
  int keyCode = event0.getKeyCode();
  if (condition) // optional
  {
event.cancel();
  }
}
  }
});
