Dreamweaver Help / Server behaviors, databases, and bindings in Dreamweaver CC
This document addresses queries around server behaviors, the Bindings panel, and databases in Dreamweaver CC released on June 18 2013.
In Dreamweaver CC, server behaviors are available as an extension, Deprecated_ServerBehaviorsPanel_Support.zxp. After you install the extension, the server behaviors feature is enabled and extensions dependent on it work as they did previously.
In the CC release, based on your OS, you can find the extension at the locations below.
- Vista/Windows 7: C:/Program Files (x86)/Adobe/Adobe Dreamweaver CC/Configuration/DisabledFeatures
- Mac OS X: /Applications/Adobe Dreamweaver CC/Configuration/DisabledFeatures
Note:
MXP type extensions are not supported in Extension Manager CC. The MXP format has been replaced with the ZXP extension format.
An MXP extension can be converted to a ZXP extension using the “Convert MXP Extension To ZXP” tool. This tool can be found in the Tools menu in Extension Manager for CS6.
