[tauruslib-devel] [PATCH] Fix bug-256: make models store a strong ref to parent

[<cpa...@ce...>]

From: cpascual <cpa...@ce...>

TaurusModel stores a weak ref to its parent. If the parent is not
referenced elsewhere, the getParentObj API does not work as expected.
Fix by making TaurusModel store a strong ref to parent instead of a weak
one.
