The problem is that when you use expression this.size > 0 it tries to call
method getSize() which does not exist. Unfortunately straight method calls like
this.size() are not supported(by EL and Stripes?).
You can bypass this problem by using validation method (@ValidationMethod) for
checking the size of the list.
