call javascript function in JSP (placed in Frame object) from GWT (works in IE but not in Firefox)

hi,

I have a JSP placed in a Frame object. The Frame has the id
'oldWebFrame'.

Frame frame_ = new Frame();
frame_.getElement().setId('oldWebFrame');

The JSP has a Javascript function called updatePattern().

I define a JSNI call in GWT:

public native void updatePattern() /*-{
var f = $wnd.frames["oldWebFrame"];
f.updatePattern();
}-*/;

It works ok with IE but with Firefox I get an error ("f is
undefined").
Does I need to make a different call for Firefox ?

Thanks !
pep
