ROBlink highlight: (ann presentation view raw elementFromModel: ann value) ]. ]]]]. tabulator transmit from: #index; to: #visualization port: #selection. tabulator transmit from: #visualization port: #selection; to: #index port: #selection. ]. browser openOn: (1 to: 42) _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
