-------------------------------------------------+--------------------------
Reporter: JesusTorrado | Owner: joyner
Type: defect | Status: new
Priority: minor | Milestone: sage-5.6

-------------------------------------------------+--------------------------
Currently, relabelled Cartan types lack some methods such as
cartan_matrix():
{{{
sage: A3r = A3.relabel({1:2,2:3,3:1})
sage: A3 = CartanType("A3")
sage: A3.cartan_matrix()
[ 2 -1 0]
[-1 2 -1]
[ 0 -1 2]
sage: A3r = A3.relabel({1:2,2:3,3:1})
sage: A3r.cartan_matrix()
---------------------------------------------------------------------------
AttributeError Traceback (most recent call
last)
/space/ga98mup/sage-5.4-linux-64bit-
ubuntu_12.04.1_lts-x86_64-Linux/<ipython console> in <module>()
AttributeError: 'CartanType' object has no attribute 'cartan_matrix'
}}}
This should be solved by adequate calls to
CartanType._abstract._add_abstract_superclass().

Current issues:
- Doctests fail for type_relabel.py (related to dynamic classes?)
