Since 'activated' is a String, try swapping your single double quotes,
e.g.
s:if test='%{warning.activated==Y}'

Hi Struts 2 users:
I was wondering if you can use a s:if test based on a pojo's
attribute value:
POJO:
public class Warning{
String text;
String activated; // Y or N
}
JSP:
s:if test=*%{warning==null}*
-- *Warning* null!
/s:if
s:else
-- *Warning* not null!
-- Activated: s:property value=*warning.activated*/
s:if test=*warning.activated == 'Y' *
-- *Warning* *activated*.
/s:if
s:else
-- *Warning* *deactivated*.
/s:else
/s:else
The first test (check null value) works OK, but the second always goes
through the else part.
I have tried test=*%{warning.activated == 'Y' } and
*test=*%{#warning.activated
== 'Y' } *too but it doesnt work either.
I dont know what is wrong, s:property value=*warning.activated*/
shows
the value correctly...
I know I can use an auxiliar boolean variable depending on the value Y/N
but
I would like to know why it doesnt work this way.
THANKS IN ADVANCE

The key is understanding *why* it makes a difference.
The reason is that a single character demarcated by single quotes is not
a String, it is a character. The character 'Y' is not equal to the
String Y.
