Are any of these pages using DW templates. I've run into problems using DataAssist w/DW templates. I was getting this message when using Multiple Delete behavior:
---------------------------
Adobe Dreamweaver CS3
---------------------------
While executing canApplyServerBehavior in WADA_MultiDelete.htm, a JavaScript error occurred.
---------------------------
OK
---------------------------
When I remove the DW template I don't get it any more.
