Hi Jason, I'm having exactly the same issue when trying to apply a Spry Radio Validation. Last night I bought a brand new laptop, Windows 7 Basic, 64 bits, 8GB RAM, Dreamweaver CS6 (12.0 Build 5808) and the only extensions I have installed are these and in this order:
1 Ajax Automcomplete 1.2.0 (DMXZone)
2 CSS Image Gallery 1.1.4 (DMXZone)
3 Sliding Panels 1.0.7 (DMXZone)
4 Universal Data Exporter 1.1.4 (DMXZone)
5 Universal Form Validator PHP 1.5.6 (DMXZone)
6 eCart 5.0.6 (Webassist)
7 Design Extender 1.1.1 (Webassist)
8 Data Bridge 1.0.8 (Webassist)
This is the error message I'm getting:
"While executing onClick in SpryValidationRadio.htm, the following JavaScript error(s) occurred: At line 132 of file "C:/Program Files (x86)/ Adobe/Adobe Dreamweaver CS6 / Configuration / Shared/Spry/DesignTime/EditingUtils.js": WA_getDocumentDOM is not defined"
Can shade some light on this? Remember, it's a new brand computer, nothing was installed prior to these extensions. Thanks much.
