ColdFusion Mappings and Relative Paths
No comments · Posted by Elliott in Adobe, ColdFusion, Programming
Recently one of our applications started failing inconsistently with strange errors about certain files not existing. We’d see error emails about things like the /myapplication/views/pages/survey.cfm not existing which didn’t make any sense since /myapplication is a mapping created inside the Application.cfc <cfset this.mappings[“/myapplication”] = expandPath(“../”)> See the bug there? ExpandPath() is relative to the requested […]

ColdFusion arguments.callee
12 Comments · Posted by Elliott in Adobe, ColdFusion, Programming
Last night Ben Nadel sent me an email asking if there was any way to get the currently executing function so you could get the metadata from it. <cffunction name=”test” myAttribute=”1″> <— How can we get the myAttribute value? —> </cffunction> The first obvious attempt at this is to use getMetaData(test).myAttribute, and that works fine […]

Getting the Expected Results for GetCurrentTemplatePath() in a Custom Tag.
9 Comments · Posted by Elliott in Adobe, ColdFusion, Java, Programming
While working on the template system used for the conference websites I ran across a problem where I needed the path to the template that called a custom tag. The first thing I tried was getCurrentTemplatePath() thinking that it might return that since the documentation makes no mention of custom tags. Instead, however, the function […]

ActionSctipt 3.0 Array Access Woes
No comments · Posted by Elliott in ActionScript 3.0, Adobe, Flex, OS X
With the recent launch of Apollo Beta I thought I’d look into Flex again for some fun and decided I’d write plist api so that Apollo applications could read and modify OS X plists in a sane maner. PList XML is particularly problematic because of how its structured: <dict> <key>Foods</key> <array> <dict> <key>Chocolate</key> <true/> </dict> […]
