Strange behavior with deepcopy

Specific Domains Optimization (Mathematical)

Ok. Thanks @odow!
There is any workaround? If I remove internamModel, for example?

Copy isn’t working for me either in JuMP 0.18.5, there is an issue with matrix constraints:

using JuMP
using CPLEX

m = Model(solver = CplexSolver())
@variable(m, 0 <= x <= 2 )
@variable(m, 0 <= y <= 30 )

@objective(m, Max, 5x + 3*y )
@constraint(m, 1x + 5y <= 3.0 )
@constraint(m, cons[i = 1:2, j=1:2], i*x + j*y <= 3.0 )
copy(m)

MethodError: no method matching copy(::Array{JuMP.ConstraintRef,2}, ::JuMP.Model)e[0m
