GoogleCodeExporter commented 9 years ago 
Found in Release: 1.1.2

Platform: GWT 2.1

Within the GWT Code i try to load a custom datasource using the Query function:

Query query = Query.create("sample");
query.send(new Callback() {....

that error comming up:

com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.google is 
undefined

if i use the custom datasource (from the custom datasource example) within an 
html page like that: 
var query = new google.visualization.Query('sample');
query.send(handleQueryResponse);

it works without any issue.

The error $wnd.google is undefined usually means the API isn't loaded yet:
