MIMWAL has some useful looking functions. I am curious about the functions: ParameterValueAdded and ParameterValueRemoved
The documentattion for ParameterValueAdded states: "Returns the added values of a multi-valued request parameter of an arbitrary request".
The example given in the wiki is: ParameterValueAdded([//Request/RequestParameter], "ExplicitMember")
What is an arbitrary request??
What I hope to do is to use this function within an action workflow triggered by an MPR monitoring adds to a multi-value attribute, FormSelectedADgroups in my case. So my action WF has the WAL Update Resources activity, and I want to call this function to act on my data.
What should the value expression be in my case?
