I've Googled a bit on this topic and thought I'd toss it out to the list to see if anybody has a solution to my problem.
I have a .jsp that needs to have four multi-select lists populated by four HashMaps that sit in the request object.
I can populate things just fine but when it comes time to validate the form submission things start to break.
I'm assuming I have to make the attributes in the bean a String[] or similar array but I'd like to be able to check for length == 0 and other subtle checks with the validate() method before I pass things onto the Action.
Anybody have a bit of sample code or a link to something easy and straightforward (!) that I can look at?
Thanks in advance,
Jon
