[z3-five] Can't call absolute_url on a z3 view in z2.10

[Derek Richardson]

In z3, I can call absolute_url on a z3 view in a zpt, like so:

view/@@absolute_url

Adjusting for z2 vs z3 nomenclature, I should be able to do this in z2.10:

string:${view/absolute_url}

However, I get a traversal error:
