WIP: erp5_simulation: fix Rule_view crashes if a Category Membership Divergence Tester tested property is not set
There is two commits, I don't know what is the best one.
it uses "listbox_tested_property_list" and not "listbox_tested_property", so it uses
getTestedPropertyList()that may return
[None]... and fails to render
Nonebecause it's not a string.
So, commit one : filter the
or, commit two : use
getTestedProperty()(as inner property -> "tested_property")
Does Category Membership Divergence Tester may have several tested_properties ?
In my opinion, getTestedPropertyList() should return  instead of [None]. It is no sense to test property None, and this could leads to erros. So the proper place to fix looks like mixin/equivalence_tester.py .
