Description (last modified by )
Facade sets are used in many places but there are two small errors that prevent from using it everywhere...
The first error concerns multiple categories initialisation. Here is a minimal example
class A(Parent): def __init__(self): Parent.__init__(self, category=((FiniteEnumeratedSets(),Monoids()), facade=True)
for which we get
sage: A() Traceback (most recent call last): ... AttributeError: 'tuple' object has no attribute 'is_subcategory'
The second problem concerns the behavior of .facade_for() which is better explained with a minimal example
class B(Parent): def __init__(self): Parent.__init__(self, category=Sets(), facade=True)
for which we get
sage: b = B() sage: b.facade_for() Traceback (most recent call last): ... AttributeError: 'B_with_category' object has no attribute '_facade_for'
The ticket provides the (trivial) corrections for both problems and add two doctests.

Replying to slabbe:
Note: you may use ReST syntax for citing trac ticket :

That's now done.

I modified the behavior of facade_for() in the way it was discussed on combinat-devel (see comment:3 of Travis).
