This error is still occurring .. I am using CF9 and Flash 10 plug-in on Internet Explorer. To see this error, you must goto a page where you use a flash form, then right-click in any HTML section and "view source". From the text file that pops up, scroll down to the <embed> code where the flash form is referenced (e.g. 1793746389.mxml.cfswf from your Temporary Internet Files). The source of my error occurs in the auto-generated code that is placed into the CF_RunContent(..) function. Its in the data that is being set for the flashVars. Here is the snippet:
<param name=\'src\' value=\'/PASS/518186175.mxml.cfswf\'/>\n
<param name=\'wMode\' value=\'Window\'/>\n
<param name=\'flashVars\' value=\'historyUrl=%2FCFIDE%2Fscriptscfformhistory%2Ecfm%3F&lconid=" + lc_id +"&%5F%5FGRID%5FWorkflowAlerts%5Fcacheid=D425B18E%2DFFE8%2D03CF%2DBE9 12240512355F2&%5F%5FGRID%5FCustomerRequests%5Fcacheid=D425B165%2DFFE8% 2D03CF%2DB9DA5537E5F77092&%5F%5FFORM%5FHomePASM%5Fcacheid=D425B1EC%2DF FE8%2D03CF%2DBD599062F00D5CEA\'/>\n
I'm getting it in ColdFusion 10 too, which means this bug - a simple typo - is approaching it's 3rd birthday with no love.
What a slow ship you've built. Is this why the user base is all jumping overboard for the open source CFML motorboats?
