Sorry if I caused any confusion. This thread was meant to discuss String keys.
I do have forms where I am using numeric keys and they work fine.
I think I found a solution to my problem. Struts seems to expect single quotes
for the keys when the key is string. Updated code is shown below. Also

Nothing like that, but I suggest to start over because you first
reported that you want to have a numeric key and now you say you
don't. So maybe start a new topic
The text field is also correctly populated based on the values in the hashmap
(populated from database before showing the form). So the filed is correctly
linked to the hashmap.
I have even tried using an alphabet as a separator but that doesn't work
either. But if I remove the h
The html form generated is correctly showing the key but the hashmap doesn't
have a value for 22419-23545 when the form is submitted.

Use the name and property attributes in your iterate tag, where "name" is
the name of your DTO and "property" is the name of the Map within the DTO.

Even if the results coming out of the database are sorted, throwing
them into a non-sorted Collection, like a basic HashMap, will un-sort
them. If you use a List, you just preserve the database sort order.
If you use a TreeMap, you can get the same sort order, but the TreeMap
object will go
my thought was just to let the DB do the work on the sorting. Is that bad?
