Yes, I tried:
<s:property value = "#session.myMap[#thisValue].state"/>
but it doesn't write anything at all.
I still wonder how Struts can possibly know that the objects I've put
in my HashMap are of my InfoObject type. (I'm not so good at
reflection) When I created that HashMap, first I just did "HashMap
myMap = new HashMap()", but I tried changing that into
"Hashmap<String, InfoObject> myMap = new HashMap<String, InfoObject>()"
That didn't help though so maybe you're right, Dustin, that it's not
about type conversion, but what is the error then?
It shouldn't be so hard. - Just printing the value of a property of
the object I've received from my HashMap. What is the right way to do
that?
I'd be really grateful if I could get some more help with this!
