G'day, Ummmmmm, this returns the value associated with the key... I need to do the opposite whereby I have the value and I need it's key.
Thanks.

G'day all, Is it possible to retrieve the key from a LinkedMap for a known value using the expression language syntax under JSTL 1.0? For example, I have a LinkedMap object which is being used to generate a drop down with the <input:select .../> tag from the Input taglib. Apart from needing the value selected by the user from the drop down I need to pull the corresponding key for display purposes on the next page along in the food chain. As I've already got the key/value pairs in a LinkedMap within the session context I was hoping to merely say "well here is the value from the drop down now give me the key which was used as the display text for that drop down". Does this sort of make sense?
