Editor scripts OpenOverriddenMethodDef

Purpose

Navigate to the definition of a method that overrides the currently open method in a descendent class

Description

• This is a nice script that will be very helpful to AX developers often exploring the class heirarchy when debugging, etc. You will need to navigate to the AOT less, which, generally, speeds up things
• In case there is more than one overridden method found, a listview with the possible choices is shown, where the developer can select the needed class.
• 2 versions of the code are provided, one of which uses cross references information, and the other - Dictionary class. The xRef version is generally faster.

Dynamics AX versions

Has been tested on Dynamics AX 3.0 SP3, Dynamics AX 4.0 SP1 and Dynamics AX 2009

Code

Simply create a new method in class EditorScripts and paste the following code into it.
