A small test revealed something interesting:
Removing all output from the jsp page, and printing to the console in the
toString() method of my object shows that the toString() method is called
when the property is inserted in the definition:
<tiles:putAttribute name="argument">
<s:property value="map['key']"/>
</tiles:putAttribute>
So it seems to me that the properties that are placed on the attribute for
the someminorjsppage.jsp are strings, which means i will not get the object
to work on.
It means that i would have to send the key to my someminorjsppage.jsp page,
and use this key to dig into the map of the action.
Can anybody verify for me that this would be true?
