Hi Hemant,
Any update on the fix for this issue? I am currently on Coldfusion 10 Update 12 (Windows) and am still seeing this error for flash forms. Here's the details from the Firebug console:
404 Not Found - http://mydomain.com/CFIDE/scriptscfformhistory.cfm
This error is generated for tabbed flash forms when clicking to access the different tabs.
Would appreciate an update and advice on fixing the error.
