You've got mixed resources from two different versions loading. Run a GWT compile and clear your browser cache. If that doesn't fix it, restart your IDE as well.

thanks for the advice it exactly worked with the project using smartgwt 3.0p, but.... something new is this warning showed before and after the module has been loaded:

This suggests a pre-existing and real issue in your app in which a DataSource with that ID is being created twice or in some other way getting a colliding ID. It's just being better reported now.

Hi again!!

i have some other news about the last error i posted... it�s not only appearing at the beginning. it seems that all the datasources i have are wrong :(. that�s why i attached the 2 datasource versions i use.

and i don�t understand how can i create a datasource twice?

the way i declare, an example...

final DynamicForm loginForm = new DynamicForm();
loginForm.setWidth100();
loginForm.setHeight(50);
loginForm.setDataSource(LoginCrossDS.getInstance());
loginForm.setAutoFocus(true);

am i doing something wrong?

pd. let me tell you that you do a magnificent work!

Two calls to new DataSource() followed by setID() with the same ID would do it, or two calls to DataSource.load() with the same ID. If you think it might be a framework bug, trying creating a minimal, runnable test case that produces the warning message.

**samila** · 27 Jun 2012, 12:22

thanks for your response isomorphic =) !

It is interesting that if you take LiveGrid code from SmartGWT showcase you will get this global reference waring as well.

It is happening at the point ListGrid.setDataSource(ds) and that method finds that datasource, which is created few linese before with some ID, is not loaded and perform creation of datasource again and at that point it prints out global reference warning message.

I was using latest SmartGWT 3.1d, GWT 2.4, FF and as already said, same code which is on LiveGrid showcase.

Is LiveGrid showcase wrong or 3.1d has some problem inside?

Thank you.

Hi,

I am getting this in dev mode (latest nightlies) too (afaics for all DS).
[ERROR] [com.myCompany.myApp] - 17:47:32.678:WARN:Log:ClassFactory.addGlobalID: ID:'contractDS' for object '[DataSource ID:contractDS]' collides with ID of existing object '[DataSource ID:contractDS]'. The global reference to this object will be replaced
The code used to obain them reads:

Code:

public static ContractDataSource getInstance() {  
	if (instance == null) {  
		instance = new ContractDataSource("contractDS");  
	}  
	return instance;  
}

Is this something to worry about or can it be ignored?

Thanks
fatzopilot

P.S.:
I included
<script>window.isc_useSimpleNames = false</script>
like indicated here: http://forums.smartclient.com/showthread.php?t=19963

The message "This conflict would be avoided by disabling ISC Simple Names mode. See documentation for further information." is now gone, but I still get IDCollision erros. In the Dev console, I also see things like "Class ID: 'IAutoFitButton' collides with ID of existing Class object '[Class IAutoFitButton]'. Existing object will be replaced." which suggests there is a bug in the framework (IAutoFitButton is not implemented by my code)

**Isomorphic** · 16 Jul 2012, 11:08

There is a difficult to fix issue in the framework causing the message about IAutoFitButton, this is not due to your code. So you were able to fix the message about duplicate DataSource IDs?

**fatzopilot** · 16 Jul 2012, 11:41

> So you were able to fix the message about duplicate DataSource IDs?
No, the duplicate DataSource ID warning is still there. I did not try any further so far as it does not seem to cause any problems (I hope).
