I'm somewhat new and occasional to Cold Fusion, so I'm not familiar with the support process. The cfgrid tag appears to be broken, and I wonder how one might get Adobe to fix it.
A few of the Adobe staff respond to messages occasionally, but this forum is by and large users helping other users. If you have a specific bug that you've identified, you should report it in the bug tracker: https://bugbase.adobe.com/index.cfm?event=home. Otherwise, if you have a license of ColdFusion that is currently under subscription or maintenance support, you should contact Adobe support directly if you want them to respond.
