Tikz UML relative positioning problems

Question

I try to use tikz-uml package to draw state diagrams. I am in big trouble with positioning of the states. If there is text inside the states (eg. in state0), it seems that the anchors of this state become damaged. Without text it works as expected. Another problem is the size of the parrent state. It does not fit to the sizes of the substates, if there is text in the substates. I hope somebody can help me please.
