Re: SuperDevMode & external server

Yes but it doesn't seem to have any effect. But if it was required there should be something like

Ignoring non-whitelisted Dev Mode URL: http://some.domain.com/

in the browser's JS console which I have not seen.

Re: Why Cookies will not be stored if setting Timeout = 30 days in GWT?

You're using integer arithmetic for a sum that overflows beyond the maximum positive value for an integer. So 1000*60*60*24*30 is negative.

You could try 1000L*60*60*24*30

If i run the above code then I can see output: "got currentlang" However, if I set timeout=30 days final int COOKIE_TIMEOUT = 1000 * 60 * 60 * 24 * 30;//30 days, then nothing got printed out, so "currentLang" has not even been stored if we set 30 days?

Why is that? does Gwt prevent that to happen?

Re: unable to use external javascript in GWT

public folder should be on the same level as gwt.xml file. superdev mode doesn't allow usage of <script> in gwt.xml, you have to include it in your application html file (it will be copied from public folder to target). You still can inject your scripts in onModuleLoad() of your library, but it's quite tricky.

Thanks Jim and Thomas, $wnd worked for me. But i am facing problem when i changed the location of the go.js , I moved it to the folder where gwt.xml file is present using <script src="go.js"/> but i am getting the following message.

14:40:05.077 [ERROR] [opsdashboardlocal] The Cross-Site-Iframe linker does not support <script> tags in the gwt.xml files, but the gwt.xml file (or the gwt.xml files which it includes) contains the following script tags:
go.js
In order for your application to run correctly, you will need to include these tags in your host page directly. In order to avoid this error, you will need to remove the script tags from the gwt.xml file, or add this property to the gwt.xml file: <set-configuration-property name='xsiframe.failIfScriptTag' value='FALSE'/>

And I am also confused about public folder. Should i create a public folder under my project or under src dir?

Hi ,
I want to use goJS with GWT. I downloaded GOJS javascript and put it in the sampleproject folder under war where sampleproject.nocache.js and sampleproject.devmode.js is present. In sampleproject.html i added
<script type="text/javascript" language="javascript" src="sampleproject/go.js"></script>

You shouldn't put the file there. The sampleproject/ folder will be cleared by the GWT Compiler.
Either put your script in your "public path" so it gets copied there by the GWT Compiler [1], or put it outside the sampleproject/ folder.

[1] see http://www.gwtproject.org/doc/latest/DevGuideOrganizingProjects.html

In one of the view i used
public static native void initGo() /*-{
var $$ = go.GraphObject.make;
}-*/;
when i call this function , exception is thrown:

com.google.gwt.event.shared.UmbrellaException: Exception caught: (ReferenceError) @com.amazon.ops.client.OpsMenuView::initGo()([]): go is not defined.

Can anyone please help me with this?

As Jim already said, you need to use $wnd to escape the sandbox GWT is running in and into the context of the web page, where your script is loaded.

New version 1.4.3 of jqm4gwt is available, check it out.

New version 1.4.3 of jqm4gwt is available. It's extended wrapper over jQuery Mobile.
In some sense it's alternative for mgwt, and could be used for Tablet/Mobile development in pure Java.

Styling DataGrid headers

I've configured my DataGrid with a custom CSS file like so:

public interface UsersDataGridResources extends DataGrid.Resources

{

@Source({DataGrid.Style.DEFAULT_CSS,"usersDataGrid.css"})

DataGrid.Style dataGrid();

}

private static final int DEFAULT_PAGE_SIZE = 50;

private static final UsersDataGridResources usersDataGridResources

= GWT.create(UsersDataGridResources.class);

static { usersDataGridResources.dataGrid().ensureInjected(); }

private DataGrid<User> usersGrid_

= new DataGrid<User>(DEFAULT_PAGE_SIZE,usersDataGridResources);

I've specified a normal font in usersDataGrid.css:

.dataGridHeader {

font-weight: normal !important;

text-decoration: none !important;

}

This isn't being reflected in what I see when the grid is rendered. I'm specifying the column headers as simple strings, not Cells. Is there a different property I need to configure?

Thanks,

Patrick
