[Reactor for CF] Get All errors for linked tables

[Ryan Blatz]

Hey just thought I’d share some code that has made my life a bit easier when dealing with linked tables and cascading saves.  This code will return a translated error array of all errors that the object has including child objects (and their children and there children’s children…)   I put this in the model\data\record\[tablename]Record.cfc files (you could possibly put this in the abstractRecord.cfc instead of all your Record.cfc files if you wanted to modify they reactor core but I haven’t tested that and it makes upgrading reactor a messy affair).   Any comments or suggestions are welcome.               <cffunction name="getAllErrors" returntype="array" access="public" output="false" >                         <!---                         steps:                         1.
