nope, not that strange.
if you viewed the source of your page, you should be able to see your
logic tags, still sitting there, unprocessed as text.
The container will only complain about undefined tags if there is a .tld
defined with
a prefix at the top of the page (ie the struts-logic tags). Otherwise it
treats everything
else as plain text.
