Hi, I've got a problem with the Visualization API. Until recently the code below worked just fine. But now I get the error:
[ERROR] Unable to load module entry point class gwtVisualiztion.client.GWTvisualization (see associated exception for details) com.google.gwt.core.client.JavaScriptException: (TypeError): Object expected number: -2146823281 description: Object expected According to the FAQs this is caused by a problem with the AJAX loader script. The script tag however is part of the html code and the script can be reached with the browser. Any suggestions what might be wrong / or how to solve the problem avoiding writing Runnable Java classes?
