Hi all!
I'm developing a simple e-commerce web project for school, and today I had some troubles using validation framework built-in with
Struts 2.
As discussed in
this thread, it seems that Struts 2 simply ignore the fact that fields that should contain numbers, are empty. In other words, an empty
string is considered to be a valid number.
I would like to solve this problem using XML only, is it possible? I know I could check fields within the
Java code, but I think it's not the best solution.
I tried to use some validators (regex, required, requiredstring) before the <field-validator type="long">, but none of them worked. I suppose the reason's that all non-number validators expect a String from the getter, but they receives a long.
Any idea?
