Adam, the problem is not so much with displaying the values in the nested objects,
it's having
struts update the nested values from a form control to the actual nested object. That
is, if I have
a textbox which represents the value for address(texas)[0].street1, when the user
submits a value
for that field I want struts to automagically do:
((Address)formBean.getAddress("texas").get(0)).setStreet1("value from field on form");
Is this how the nested taglib works? I know nested has been around for a while but I
am so of the
camp "don't use unless you have to" that I never have used it. And up until now the
standard html
taglib has worked great with nested properties.
Craig.
