Cause:
=====
There is a problem with the declartion of one or more variables. The 'Scope' of one or more rules will define a variable as "Integer". This must be changed to 'int'.  Search the Studio project for "Integer" to find the incorrect definition. This has been fixed in version 5.0.x.

Another problem can be that a variable is declared as Date instead of DateTime. Date is a function category rather than a type.

Resolution:
=========
Make the above change or changes.  Note that "Integer" may be used in the body of a Rule.
