Subject Re: HashMap with String as key
Date Thu, 14 Mar 2019 19:10:45 GMT
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?
