Stange error with Chrome hosted mode

[mjfan80]

Hi to all
There was and old topic on that error, but i can't find it anymore...
i found it on google but the page doesn't exist either in the google
cache.

I'm tryng to use the hosted mode in chrome too... but i can't.

I can use it on IE and Firefox (in this day i can't with firefox,
because the plugin in is not compatible with the last firefox
updgrade).
My project in "normal" mode works also in Chrome, but in hosted mode i
get this error



onModuleLoad() threw an exception
Exception while loading module com.fdlservizi.sse.client.HelpDeskGWT.

I'm using GWT + GWT-EXT and the java code and the point of the failure
is:

VerticalPanel vp = new VerticalPanel();
vp.setHorizontalAlignment(HorizontalPanel.ALIGN_CENTER);
vp.setVerticalAlignment(HorizontalPanel.ALIGN_MIDDLE);
vp.add(logoWelcome);
Panel pannelloVuoto = new Panel();
pannelloVuoto.setHeight(150);
vp.add(pannelloVuoto);
logoSA = new Image();
logoSA.setPixelSize(300, 90);
vp.add(logoSA);
pannelloInterno.add(vp);
panelPrincipale.add(pannelloInterno);

(the line 107 is: vp.add(logoSA);)
so nothing special

Some one can help me?

Caused by: com.google.gwt.core.client.JavaScriptException: 
(TypeError): Object [object Object] has no method 'push' 

and

at com.gwtext.client.widgets.Container.addPreCreate(Container.java) 
at com.gwtext.client.widgets.Container.add(Container.java:202) 
at com.gwtext.client.widgets.Container.add(Container.java:144) 

indicates that GWT-EXT trys to call a method "push" on a javascript object that does not provide this method. This is done somewhere in com.gwtext.client.widgets.Container.addPreCreate(). 

I don't know GWT-EXT but maybe you have some old libraries of GWT-Ext or missed to initialize some GWT-EXT specific stuff?

Maybe, but the fact is that

1: GWT-EXT is an "old" library, not maintened anymore
2: with Firefox and IE, also in hosted mode, i don't have any
problem... either with chrome in web mode. I have this error only with
chrome and hosted mode
