Ok, now we have a clear situation. The "name" attribute is evaluated
as an OGNL expression so in this case everything enclosed will be
parsed and treated as expression, from inner to outer.
Using "%" forces an additional evaluation but enclosing it in a single
quote (') means you expect a String so this expression
'%{#attr.mapKey}' should only return '12345-123', then
"accountAllocation[]" is evaluated as a map with a key (in this case
with a String key).
So using single quotes should do the trick in your case.
Kind regards

Re: HashMap with String as key
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 I changed my separator to "a" rather than "-". So the two changes I have made are i) change separator to "a" ii) use single quotes around the key when specifying the name for text field. JSP: Resulting HTML: Appreciate the input from everyone.

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 with an example code. I assume you have defined a numeric key in your Map and Struts tries to convert "2432-123" into a number and trims after the non-numeric character, that's why you see only "2432".

Re: HashMap with String as key
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 hyphen (2241923545 as key) then the hashmap is populated, but I wouldn't be able to get the two values separated out if there is no separated. I could multiply one number with million and add another number to come up with a single number, but it will eventually create a problem as these keys grow. If there a setting for struts that need to be changed to allow non numeric keys?

Re: HashMap with String as key
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.

Re: HashMap with String as key
Lukasz, There is no new keys in the hash map. The hash map is not updated at all. Before the form is displayed to the user, the hash map is populated based on the data in the database. These values are correctly displayed to the user in the text fields. But when the form is submitted by the user the data doesn't get populated in the hash map. Only the data I have populated in the hash map is present (as the model class is stored in session using scope interceptor) doesn't matter what values I type in the text fields. Yasser, That is right the key is a string, not long. Also as I was testing this (having keys with and with out hyphen) I realized that any values that I have added to hash map before showing the form are still in the map. The new values from the form (keys without hyphen) got added to the hash map. I was under the impression that struts would set a new hash map with just the keys present in the form.

(regarding your previous emails background) Please also consider that the key 2432-123 is not further Long. It's String.
