I don't believe it is possible to control the visibility of a parameter based on the value of another one. To do this it would probably be necessary to change client-side javascripts of the birt viewer, which might be tricky.

May be you could envisage to design a single cascading group with 3 levels, set as "multiple datasets":

- First level: 3 items to select "By area", "By region users" or "All regions". We can make use of a scripted dataset to fill a such static list in a cascading group
- Second level: Regions (or nothing if "All regions" is selected in first level)
- Third level: Areas or Region users, depending on the value of level 1. The dataset of this level should have a script "beforeOpen" to change the query accordingly.

Well, i know this is quite different from what you want but this should natively work.
