html:options ordering
I have a hashtable with key/value that get displayed by an html:options
tag.
Works ok, but they are ordered in reverse order of the id. That isn't
any performance problem, but it looks a little strange to the user.
For instance, what if you wanted the options in alphabetical order? In
my case, I need them ordered by the key for each options.
Any Suggestions?
TIA
-Dennis

if you're using jdk1.4, try java.util.LinkedHashMap which preserves
insertion-order.

Hash Tables don't guarantee order when you pull them out enmasse.
probably best bet is to store it in a list and sort accordingly
(Collections.sort).

Thanks for the comments. Seems to make more sense not to have
any ordering functionality in the html:options tag anyway.
