#645 Cant wire copied godley table variables

[Hal Crichton-Standish]

While it is possible to attach a wire to the left side of a godley table variable, it is not possible to do so with a copied variable. This may be related to the disappearing variable issue.

It specifically does not seem to work under these conditions: create a godley table, enter values, copy one of the variables, create a new icon (e.g. multiply). It doesn't appear to be possible to wire this new icon to the left hand side of the copied variable.

Also when wiring the copied values of two asset classes to a plot, the values disappear (see image).

Seems OK with the new canvas
