write/read model with renaming: dynamic inputs error

[alexeybaran]

import modelx as mx
m=mx.new_model('a')
def s_arg(t):
    pass
s=m.new_space(formula=s_arg)
@mx.defcells
def b():
    return 1
s(1).b[()] = 2
m.zip('a.zip')

In a separate console window:

import modelx as mx
mx.read_model('a.zip','e')
