Run GWT mobile showcase sample code error.

[cooldean]

Be sure your post includes:

1. I am trying to run smart GWT mobile with showcase forms/SwitchItems element. The browser displays it success at beginning. However, when I try to switch them, I get an error below. I am wondering if you can give me a hand or not. Thanks.

Browser: Google Chrome Version 24.0.1312.57.
GWT mobile version: smartgwt-mobile-1.0d_2013-02-07

Error :

[cooldean]

it works in Firefox 18.

It is quite strange. I try to execute it on Firefox 18, and it works. However, I still don't know why same sample codes can not be executed in Google Chrome.

I am wondering if someone can answer me.

[Isomorphic]

Thanks for catching this - it was a regression only affecting desktop browsers. It's fixed for tomorrow's nightly build.

I got the same problem with smartgwt-mobile build 2013-05-23, gwt 2.5.1, chrome 28.0.1500.20

[Isomorphic]

Please provide steps to reproduce this problem - the steps above don't reproduce the problem anymore.

[SimonLei]

The code looks like this:

public class MainContent extends NavStack<NavigationButton> {
public MainContent() {
super("main", IconResources.INSTANCE.files());

ScrollablePanel overview = new ScrollablePanel("main", IconResources.INSTANCE.home());

DynamicForm form = new DynamicForm();
SwitchItem onlyMine = new SwitchItem("mine", "only mine");
form.setItems(onlyMine);

overview.addMember( form);
push(overview);
}
}

When I click the switch item, the exception is thrown.
BTW: After I compiled it, the page works fine.

[SimonLei]

I debugged the exception, found it was thrown by the method
@com.smartgwt.mobile.internal.gwt.dom.client.WindowAnimationTiming::requestAnimationFrame(Lcom/smartgwt/mobile/internal/gwt/dom/client/WindowAnimationTiming$FrameRequestCallback;)

So I think it should be the problem of the animation. I check the
SwithItem's implements, there are two: SwitchItemImplDefault and SwitchItemImplRAF. I found when the user agent is safari,
it will use SwitchItemImplRAF. So I changed my chrome's User Agent to "Firefox 14 Android Mobile", then it works fine.

[Isomorphic]

We need code we can actually run to reproduce the problem.

[SimonLei]

I posted code in this thread before, there is a simple way to reproduce it, just replace the About.java in the showcase project:

package com.smartgwt.mobile.showcase.client.overview;

import com.smartgwt.mobile.client.widgets.NavigationButton;
import com.smartgwt.mobile.client.widgets.ScrollablePanel;
import com.smartgwt.mobile.client.widgets.form.DynamicForm;
import com.smartgwt.mobile.client.widgets.form.fields.SwitchItem;
import com.smartgwt.mobile.client.widgets.icons.IconResources;
import com.smartgwt.mobile.client.widgets.layout.NavStack;

public class About extends NavStack<NavigationButton> {

    public About() {
        super("About", IconResources.INSTANCE.info());
        ScrollablePanel overview = new ScrollablePanel("main", IconResources.INSTANCE.home());

        DynamicForm form = new DynamicForm();
        SwitchItem onlyMine = new SwitchItem("mine", "only mine");
        form.setItems(onlyMine);

        overview.addMember( form);
        push(overview);
    }
}

When I click the switch item, the exception is thrown.
BTW: After I compiled it, the page works fine.

This has been tracked to what appears to be a bug in GWT Dev Mode and fixed for tomorrow's build.

This compilation error results from changes in GWT 2.6, and is fixed for tomorrow's build.
