HashMap with options
Hi Can i use HashMap with options? something like: such that the option value is the key and the labelProperty is the value? thanks M
Re: HashMap with options
You might want to investigate using a List of LabelValueBean objects instead.

However, your needs a name attribute if you're going to use the property attribute. -- Michael D.

RE: HashMap with options
Hi Michael,
Thanks for your reply - I'll definitely give it a go!
Could you elaborate what happens when I specify the name along with the
property attribute? Does struts iterate through each item in the Map,
calling get("key") and get("value") on each item in the Map? Is there any
link/website where I can read more about this?
Many Thanks
M

The "name" attribute tells the tag what key to use in the
page/request/session/application scope. Without it, you're trying to
get a property from nothing.

The tag iterates over the Map's entrySet(). It then
calls getKey() and getValue() on each Map.Entry for the options.

I honestly don't know. I usually just read the source.
