Ok. I tried with that version.

Ok. I tried that code and while I have to say that, it works fine for me.

Just write $!{myMap... and it won't bother you anyway. :-)

Hm. Maybe I'm getting something wrong. Where do you get this exception? On
screen / in the template? In a log file? I can't reproduce it but I'd love
to. Do you load any velocity.properties? From your code I'd say not.

Sure. java.util.List::set(int index, Object element)
>2. ${myMap.put("tttt123", "test")}
Works fine for me.
>or
>3. $myTable.put("test", "hallo")
Works fine for me, too.
>Any ideas why it works in case 1 and not in case 2 and 3?
I'd like to see the exception. Can you send it to me (either through the list
or directly).
Best regards
