Summary [Texmap] [Qt] [WK2] Unsync in TextureMapperNode between parent and child list...

Reported 2011-06-13 12:33:29 PDT
In TextureMapperNode::syncCompositingStateSelf in ParentChange "if" statement m_parent gets overwritten 1st and node gets removed from new m_parent child list and never added. In ChildrenChange m_children list gets cleared, but m_parent members of child nodes are not cleared. This cause unsync in m_children <-> m_parent linkage and random crashes mostly ~TextureMapperNode(), but also in other places when already deallocated node gets referenced because it wasn't removed from child list.
