Issue 16044: OCL 2.3 Pathname syntax does not allow access to hidden names (ocl2-rtf)
Source: Nomos Software (Dr. Edward Willink, ed(at)willink.me.uk)
Nature: Uncategorized Issue
Severity: 
Summary: If meta-models provide both 'B::x' and 'A::B::x', it is not possible to access 'B::x' from a context with 'A::B' since 9.4.1[4] searches from the current scope and so resolve 'B' in 'B::x' to 'A::B'.


Suggest adoption of the C++ '::' global prefix so that '::B::x' can be used when 'A::B' occludes.

Hi


If meta-models provide both 'B::x' and 'A::B::x', it is not possible to access 'B::x' from a context with 'A::B' since 9.4.1[4] searches from the current scope and so resolve 'B' in 'B::x' to 'A::B'.
