Now I see what you mean. What 'push' does is to put a value on top of
the stack. The name attribute is a string, not an expression, and
doesn't use the stack for anything. That is why it wouldn't work.
There is a simple workaround tho,
you can set a variable for it like:
<s:set var="prefix" value="%{''person'}" />
.....
<s:textfield name="%{#prefix + '.x.y.z'}" />
....
or even
<s:textfield name="%{#prefix}.x.y.z'}" />
I dont remember if the second option works.
