Try using the "var" keyword in your first four <cfset> statements.
<cfset var root_node = Arguments.node> <cfset var levels = ... -----Original Message----- From: Cedric Villat [mailto:[EMAIL PROTECTED] Sent: Thursday, September 18, 2003 12:59 PM To: CF-Talk Subject: Recursion and Scope problem? Ok, I'm doing a bit of recursion, and my variables seem to be overwriting themselves, which makes no sense to me. Here is my code: <cffunction name="getDTreeWidth" returntype="numeric"> <cfargument name="node" type="string" required="yes"> <cfargument name="level" type="numeric" required="yes"> <cfset root_node = Arguments.node> <cfset levels = Arguments.level> <cfset children = Request.children> <cfset width = 0> <cfif levels EQ 0> <!--- No more levels to show ---> <cfset width = 1> <cfelseif NOT StructKeyExists(children, root_node) OR ArrayLen(children[root_node]) LTE 0> <!--- No Children ---> <cfset width = 1> <cfelse> <cfloop from="1" to="#numChildren(root_node)#" index="a"> <cfset width = width + getDTreeWidth(children[root_node][a], levels - 1)> </cfloop> </cfif> <cfreturn width> </cffunction> In this example, the root_node is "Homer Simpson". He has 3 children Bart, Lisa, and Maggie. When the function is first run, Arguments.node is "Homer Simpson". It goes through the code until it gets to the recursive call getDTreeWidth() which then calls itself for each child. After calling getDTreeWidth() for Bart, it seems to work. When the function returns a number and is added to the width, the next time through Homer Simpson's loop, the root_node is now "Bart Simpson"! How could the recursive call to Bart Simpson overwrite Homer Simpson's original arguments? Is this a bug or am I missing something here? Any help would be appreciated. It may not make sense, so let me know if you need some more clarification.
