Did your form beans work in previous Struts version and now you have to change 
all? Or you get this error always with all Struts versions?

I checked, and double value comes from ongl,  and yes it wont be a null, so
does not get validated.  I get the struts error though.  I have had to
change all my form beans to be Doubles.
https://struts.apache.org/core-developers/required-validator.html could do
with an update warning no not to use primitives.

 Has there been any changes, or has it always been like this?

 Did you mean it works in some versions as you expect?

 I think the primitive type double, cannot be null at all in java and
 automatically will be initialized to 0 by java i.e. you don't need a
 null validator in such situations. The non-primitive type Double, can.
 This may explain why when you change your type to Double it starts working.
