<s:property /> is like out.println(). It is useful for printing
(outputs) some value, but not to store a value.
To store a value in to the value stack (coz this is S2), you may use
<s:set name="" value="" /> where the name attribute indicates the name
of the variable and the value indicates the value to be store. You may
use another attribute 'scope' to tell the scope of the variable. Ref
http://struts.apache.org/2.x/docs/set.html
Ex:
<s:set name="flag" value="true" />
<s:if test="#flag">
<%-- Write your code here --%>
</s:if>
Here as the 'flag' variable is stored in the value stack, to access this
variable you will need to use the variable prefixed with #, like
#variableName
In some cases <s:push /> is useful. Please go through the doc for
<s:push /> which is used to push the current element into the top of the
value stack.
hope this helps.

Hi konference
I am already helpless.
How can I test the property in <s:if tag?
-----------------------------------------------------
<s:iterator id="comp" value="%{components}">
<s:property value="%{sort}" />
<s:if test='%{#sort eq "PRODUCT"}'>
OK
</s:if>
</s:iterator>
----------------------------------
Thanks a lot.
