Changing tree to Tree works. Thank you.

Unfortunateliy the ANTLR book has very little to say of the issue (or I just don't know where to look) and the sample grammars that I see seem to implement the 'walker' different from the way ANTLR does it now. For example in the CSharp grammar there is syntax like (the 'walker grammar names are different):
