texte = Upgrading from 3.0, you need to be aware of one particular change to the WebDNA engine (introduced with version 4). This has to do with the 'switch' in precedence between text or math variables, and incoming form variables. Prior to WebDNA version 4, incoming form variables would 'override' any text or math variables of the same name. Starting with version 4, the default behavior of the engine was changed so that incoming form variables would not take precedence over text and math variables. This was a necessary 'security' improvement. However, it did require some WebDNA programmers to make changes to their existing templates. If much of your WebDNA code relies on the 'old' engine behavior, there is a way to get a newer WebDNA version to run in pre 4.0 mode. Simply set the WebDNA 'InsecureTextVars' pref to '1', and newer WebDNA versions will revert to the original method of resolving form varibales, ahead of text variables. I do not recommend doing this, however. Instead, I would just make the necessary code changes. For example: If you are used to setting default values for text variables, anticipating that incomming fcrm variables will 'replace' the default values, you can make the following change: [Text]Var1=some_default_value[/Text] becomes [Text secure=F]Var1=some+default_value[/Text] In this case, [Var1] will resolve to the default value, unless a formvariable, also named 'Var1' has been passed to the template. -----Original Message----- From: WebDNA Talk [mailto:WebDNA-Talk@talk.smithmicro.com]On Behalf Of Alisha Outridge Sent: Sunday, March 21, 2004 1:31 PM To: WebDNA Talk Subject: WebDNA 6.0 backwards compatible?
