Polymorphism through s:textfield

[Kumar Iyer <iy...@gmail.com>]

Hi all,

This is a conceptual doubt:

Let there be an action class member "t" of type "T".
For a <s:textfield name="t.a"/> in the JSP, a new instance of T will be
created and the member variable of T,namely a, will be populated with the
value entered in the textfield.

I have a scenario wherein depending on the user's selection (java-script
action), I must create one of the run-time instances of T, say X, Y or Z.
Subsequent values the user enters will sit in one of these instances.

Is there anyway I can specify the actual instance of T in the <s:textfield/>
tag?
My intention is to have a single action class member definition "T t". I can
live with 3 different <s:textfield/> tags in my JSP.

Regards,
Kumar.
