This is a bit slower (due to internal locking), but less code.

Subject: [Seaside] Generating a random string
I'm trying to generate a random string, and i've created a method to do
so based on a few things I found on internet. However, when I try to
generate the string, I receive the error : "Improper store into
indexable object".
The error comes when I try to insert a new random character into my
string.
here is my code.
*randomString:* aSize
| alphabet word |
alphabet := '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ'.
word := String new: aSize.
1 to: aSize do: [ :position |
word at: position put: [ alphabet at: ( Random between:
1 and: (alphabet
size) ) ] ].
^word
Any help?
