Corechart doesn't work

[GoogleCodeExporter]

Found in Release:
I'm trying to display PieChart from the CoreChart package.
with library 1.1.1

Platform information (OS, Browser, GWT version).  Does the issue exist on
other platforms?
windows 7 64bit inside a Apacahe Tomcat server a JRE 32.
GWT 2.0.4

Any browser.

Give a Detailed description of the problem.  If possible, please include
some code that reproduces the problem and a verbatim copy of any error
messages you can find.

When I try to display a pie using the corechart package I get the message 
"Object Expected". It happens if I use the GWT-Visualization 1.1.1, or if I use 
the 1.1.0 with the string "piechart".

I'm able to run this HelloVisualization Example of visualization 1.1.1. But I 
when I try compile exactly the same example I'm getting the Object Expected 
message.

Workaround if you have one: I don't have any workaround

Any one has any workaround?

You cannot use the string 'piechart' with the newer functionality.  Use 
'corechart' instead.

I am having the same issue. I am using the corechart with smartgwt. Below is 
the alone code I am using with smartgwt & gwt-visualization.jar 1.1.1 
integration. I copied most of the code from gwt visualization 1.1.1 examples. 
This seems like an issue with visualization api and there seems to be no work 
around?

smartgwt users, there has been an update to the smartgwt project that might 
help you: see http://code.google.com/p/smartgwt/issues/detail?id=405

The problem seems to be solved using latest nightly build from smartgwt.
