You can edit any server behavior created with the Server Behavior Builder, including server behaviors you download from the Macromedia Exchange website, and other third-party developers.
If you apply a server behavior to a page and then edit the behavior in Dreamweaver, instances of the old behavior will no longer appear in the Server Behaviors panel. The Server Behaviors panel searches the page for code that matches the code of known server behaviors. If the code of a server behavior known to the panel changes, the panel will no longer recognize earlier versions of the behavior on that page.
The Edit Server Behaviors dialog box appears, displaying all the behaviors for the current server technology.
The Server Behavior Builder dialog box appears.
For instructions, see Creating a dialog box for a custom server behavior.
For instructions, see Positioning code blocks.
Dreamweaver regenerates the server behavior without a dialog box. The new server behavior appears in the Plus (+) pop-up menu of the Server Behaviors panel.
Dreamweaver asks you whether you want to create a new dialog box, overwriting the old one. Make your changes and click OK.
Dreamweaver saves all changes in the server behaviors EDML file.
