Hi Stan,
Thanks a lot for your follow-up.
This Mashup server has been running for about one year. I believe most of error messages are generated by other mashups, e.g. StrikeIron widges. In order to show you so, I did the following steps to get clean log files,
1)Stop mashup server,
2)Empty SystemOut.log
3)Start mashup server,
4)Copy SystemOut.log to SystemOut_Start.log
5)Create a page and add a Google gadget widget.
6)Copy SystemOut.log to SystemOut_GoogleGadget.log
I attach both log files to you (one in next reply), which seems to have no error at all.
I did a further step to analyze this problem. I open the JavaScript debug in IE. When I add the GoogleGadget Widget, it shows the following error message,
Object doesn't support this property or method eval code, line 734 character 3
The code line is,
var eventModel = iWidgetContainer.find(this.iContext.widgetId)._getPublicEvents();
Hope this information helps.
Thanks.
