How is this possible? aCollection is an array with 1 element (an AdaParameter ...) but each in the do: block contains nil (so the add: gives a DNU) !?!?!? I have no idea how this can be possible Any clue nicolas _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev

this is the normal FMMultiValueLink>>add: anElement anElement perform: opposite with: owner. (values includes: anElement) not ifTrue: [ values add: anElement ]. ^anElement it fails because anElement is nil (because each was nil in previous step) nicolas On 14/08/2015 11:31, Guillaume Larcheveque wrote: > can you show one step above in the stack because your problem is in > the #add: of FMMultivalue link > > 2015-08-14 16:26 GMT+02:00 Nicolas Anquetil > <nicolas.anquetil(a)inria.fr <mailto:nicolas.anquetil@inria.fr>>: > > How is this possible? > > > > aCollection is an array with 1 element (an AdaParameter ...) > but each in the do: block contains nil (so the add: gives a DNU) > !?!?!? > > I have no idea how this can be possible > > Any clue > > nicolas > > _______________________________________________ > Moose-dev mailing list > Moose-dev(a)iam.unibe.ch <mailto:Moose-dev@iam.unibe.ch> > https://www.iam.unibe.ch/mailman/listinfo/moose-dev > > > > > -- > *Guillaume Larcheveque* > > > > _______________________________________________ > Moose-dev mailing list > Moose-dev(a)iam.unibe.ch > https://www.iam.unibe.ch/mailman/listinfo/moose-dev _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
