Button "Strategy" enabled when viewing the decision tree

[Manuel Luque]

When the user visualizes the decision tree of an influence diagram, the button S ("Strategy") appears enabled. If the user clicks on int then there is a NullPointerException.

In my opinion, there are two options for solving this:

1. Disable the button S when visualizing the decision tree.
2. Show the strategy of the influence diagram associated to the visualized decision tree.

Isn't it possible to show the strategy while the tree is open?

[Manuel Luque]

I suppose it is possible.
