Context variable node has the following properties:
Context variable's name.
Variable's type. Context variable could be defined based on a domain, an attribute or an SDT.
Procedure that will be invoked in order to load this variable from context (session).
The purpose of this node is to centralize in a variable all the information that needs to be used and consulted through many parts of the application. For example, save information about the application user, its role and its company in order to limit the actions he could do.
This variable will be loaded on Start Event of every object generated by the pattern, so that user can consult some information about the application or set information to it that will be relevant onwards (by saving the variable in session).
WorkWithPlus Configuration has by default a context variable named 'Context', which is defined based on an SDT named WWPContext and it is loaded by LoadWWPContext procedure. This SDT can be modified by user and will not be overwritten when re applying the pattern. In fact, the idea of having the context based on an SDT is to allow user to add new attributes to it when needed in order to have all the information about the application centralized.
The default context variable is defined base on WWPContext SDT:
As we mentioned above, the context will be loaded on stard event of every object generated:
