[jbpm-dev] Simplifying Oryx Designer using resolution of global variable and parameter mapping at runtime

[Mauricio Salatino]

Just a quick comment about mapping data,
I think that we need a specialized component to do that, because is a cross
cutting concern.
No matter if we are mapping task inputs and task outputs or a form field,
we need a graphical mapping component to take care of that.

We need a graphical way to do something like

Input: Person -----> Person.name ---- <mapped to> ----> name

and the other way around

Output Person.name <----<mapped to>--- name
