Re: [qvtd-dev] [Dev] Navigation attributes with null values

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi

The exception should be InvalidValueException which is the way invalid is generally 'passed'.

Hi Ed,

 

What is the correct way to evaluate:

 

c2t.fromAttributes.leafs;

 

if fromAttributes value is null?

 

Currently OCL throws an exception: 'NavigableObject' rather than 'OclVoid' value required.

 

I think it should return invalid so the QVT engine can deal with it, i.e. the binding is not valid then don’t invoke the mapping.
