Iterator behaving abnormally with jsp, while correctly with java

Question

So I have a class that generates a ListIterator for me, which I should process with jsp. However, the iterator behaves illogically.
In both java & jsp method i.hasPrevious() returns true, in java i.previous() returns previous element, and jsp terminates with NoSuchElementException.
I just doublechecked, the content of the iterator is in both cases exactly the same.
I am using Weblogic 6.1.
Any help,
anywhere,
jussi
// We have a ListIterator
ListIterator i = lService.listIterator(0);
while( i.hasNext() && b) {
   System.out.println( ((Map)i.next()).get("name") );
   // Some other things hereprocessing here...
} // And here we are, at the end of the iteration...
// Then we output
System.out.println( ((Map)i.previous()).get("name") );
System.out.println( ((Map)i.previous()).get("name") );
System.out.println( "More? = " + i.hasPrevious() );
System.out.println( ((Map)i.previous()).get("name") );And the output is:
K�ytt�tapaus1bPyynt�
Osakkaat
Osakas
Osakas
Osakkaat
More? = true
K�ytt�tapaus1bPyynt�
That's cool...
But the same with jsp:
<%
ListIterator i = lService.listIterator(0);
while( i.hasNext() && b)
  %><%= ((Map)i.next()).get("name") %><%
%> <%= ((Map)i.previous()).get("name") %><%
%> <%= ((Map)i.previous()).get("name") %><%
%> More? = <%= i.hasPrevious() %> <%
%>And the output is:
K�ytt�tapaus1bPyynt� Osakkaat Osakas Osakas Osakkaat More? = true
Great!
Then I add one magic line:
<%
%> <%= ((Map)i.previous()).get("name") %><%
%> <%= ((Map)i.previous()).get("name") %><%
%> More? = <%= i.hasPrevious() %> <%
%> <%= ((Map)i.previous()).get("name") %><%
%>Servlet failed with Exception java.util.NoSuchElementException
and with
%> <%= i.previous() %><%
it is, of course the same...
This one is giving me headache...

Now I should say "Damn me!", cause I solved the puzzle. I just had problems understanding the jsp-notation...
Am a bit newbie with jsp. And a bit with java.
