MappedLUN constructor fails

[schegi]

I wanted to create a mapped lun. I got a LUN object (lun) and an NodeACL object (acl). First i tried this:

'MappedLUN(acl, lun.lun, lun)' and it fails with

Traceback (most recent call last):
File "", line 2, in
File "/usr/lib/python2.7/site-packages/rtslib/target.py", line 1028, in init
+ "a NodeACL object")
rtslib.utils.RTSLibError: The parent_nodeacl parameter must be a NodeACL object

with a 'type(acl)' i could verify that it is of type:
<class 'rtslib_fb.target.NodeACL'>

But do it the other way with:
acl.mapped_lun(lun.lun, lun) it worked.

I can't reproduce. Can you give me more detailed steps to try? Also, what is the rtslib version? Thanks.
