Fix: $PAGE->context must be reset when calling validate_context Improve: Provide wrapper for calling an external function The wrapper correctly checks the function parameters and return type against the description of the external function, and stores the PAGE and COURSE global state variables, restoring them before the function returns. Fix: buggy unit tests. These tests are expecting debugging from a bug that was fixed, and calling web service functions with no user or session.
