Thanks for that prod to debug - it helped me find the problem. I used the technique described here to aid debugging.
http://code.google.com/apis/gadgets/docs/tools.html#Assumptions <http://code.google.com/apis/gadgets/docs/tools.html#Assumptions> I hadn't noticed that the GadgetHelper class was used *not only* to construct the query *but also* to validate the response (which is where it got stuck). So when I added back, the construction of the help object, function sendQuery() { // var prefs = new _IG_Prefs(); // User preferences gadgetHelper = new google.visualization.GadgetHelper(); // var query = gadgetHelper.createQueryFromPrefs(prefs); ... The handler, now works! function handleQueryResponse(response) { /** * Use the visualization GadgetHelper class to handle errors */ if (!gadgetHelper.validateResponse(response)) { return; // Default error handling was done, just leave. } ... -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
