Re: [qvtd-dev] [Dev] Assignments in QVTimperative guard patterns

Hi Ed,

 

I don’t seem to find any reference to initialisers in the metamodels or visitors. Any pointers will be appreciated.

Hi

This sounds vaguely like what I fixed with

[412341] Fix guard variable initializers

But a guard pattern has no assignments.

on the left it has predicates
on the right it has initialisers

Hi Ed,

 

I have pushed some changes in the TracingVisitorDecorator to git. Basically some emf reflection to get info about the EObjects being bound.

 

Good thing, it helped me find a bug.. or something strange. Looking at the QVTimperative.ecore (and also the QVTcore.ecore) I don’t see the GuardPattern containing any Assignments. However the QVTi editor does not complaint about them (for example the ones in associationToForeignKeyLM).  

 

The bug, I think is due to the Assigments are not being visited and hence the variables are null when evaluating the predicates.

 

This is preliminary,  and will continue with further testing.
