Hi,
we looked in the Struts source code a second time. Line 283 and 284 says:
else if (collection instanceof Map)
iterator = ((Map) collection).entrySet().iterator();
This gets you an iterator of the *mappings* in the Map. So each element is a
java.util.Map.Entry - right ?
The doAfterBody method just put a Map.Entry in the pageContext for each
mapping in the HashMap.
So you would acutally have to do two <struts:getProperty> to get to the
value of each mapping in the entry set - one to retrieve the Map.Entry and
one to retrieve the value of the entry.
Is this the right way to do this ?
Regards,
Jannik
