Hi Hubert,
Thanks for your response. It worked the way you told by using dot delimiters
to point
out the nested object. On the same lines, I have one more question. How do I
validate an array of objects. This is my class strucutre.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Class X{
String a;
Y b;
}
Class Y{
String i;
String[] j;
}
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
I could reference the nested element 'i' in class Y by using "b.i", but I
couldn't validate j;
I tried the following with the indexedListProperty construct:
<field property="b.j" indexedListProperty="b.j" depends="required"> ---failed
<field property="b.j" indexedListProperty="j" depends="required"> ---failed
<field property="j" indexedListProperty="b.j" depends="required"> ---failed
but each time I got an exception:
java.lang.NullPointerException
at org.apache.commons.validator.Field.getIndexedProperty(Field.java:780)
at org.apache.commons.validator.Field.validate(Field.java:875)
at org.apache.commons.validator.Form.validate(Form.java:174)
at org.apache.commons.validator.Validator.validate(Validator.java:367)
Could you tell me where am I doing wrong.
Regards,
Ashutosh

I've never used Validator outside of Struts, but I do know I've
successfully referenced nested elements while validating, by using dot
notation. In your case, you can refer to fields "a", "b", "obj.i,
"obj.j", "obj.obj.k".
