#foreach help needed ...
Hi everyone,
I wonder if the following thing is possible, and if it is, how to make Velocity do it...(i simplify the real situation & use different classes, but the problem is the same):
I have one class, say class Person with following fields: String name, ArrayList addresses
Then I have another class, Address, with fields String street, String city - you can guess, the ArrayList addresses in Person is filled with instances of the class Address.
And I have a wrapper ArrayList People.
Now I want to print all the information I have
so I do
#foreach($person in $people)
$person.name
#foreach($address in $person.addresses)
$address.street
$address.city
#end
#end
However, I do not get the address data ... anyone any idea why? I do not have any problems with accessing simple stuf like String inside an ArrayList. I also do not have any problems with getting the whole Address object (which is, of course, gibberish when printed as it is). What I cannot achieve is to acces the fields of the Address object from the ArrayList ....
Thanks!!!
Jan

You're right!
it was a really STUPID mistake - my getters & setters were "protected"
... thanks a lot and sorry for bothering you! Everything works fine now!

Do you have getters for the address-properties? Like
Address.getStreet()?
And are they public? Could you please send the Java-Files too, if the
problem persists?
I don't see any problem besides the property-thing (at the moment).
