Thanks for the tip, Dustin, but it's not working.
Though, I omitted the "information" part because that was only meant
to temporarily save a reference to the object that the Map returns -
an object of type InfoObject which has get- and set methods for the
property state. So I tried:
<s:if test="#session.myMap[#thisValue].state == 0">
but that still returns false though I know it should return true.
I'm wondering if it's a matter of type conversion. The get method of
HashMap returns an Object and I have not told Struts in any way that
this value should be converted to my InfoObject. Perhaps I should do
that, in an xml file or something? (I'm a real newbie at Struts 2 as
you can tell.)
