I think there may be a bug then...
When I try to use a String array in my Java class, I get the following error:
Exception trying to set value with xpath validchecks; Cannot modify property:
elrsproto.FormBean.validchecks; Cannot convert value of class java.lang.String to type
class [Ljava.lang.String;; Cannot convert class java.lang.String to class
[Ljava.lang.String;
That's why I tried to use just a straight String. And it works, except that it only
gets the value of the first check.
Whether I use the nodeset or not, I get the same behaviour.
I did verify that I don't need to use the nodeset if I specify all of the controls
ahead of time in the form definition. Thanks.
For now my work-around is to use a javascript array object for the form and then copy
it into my Java class. That works. Odd.
