[s2] If Test Conditions

I am having a devil of a time getting a simple if test condition to work
properly.  

Here is the jist of what I am trying to do:

<display:table id="idContract" name="contracts" class="results">
	<display:column 	titleKey="label.select">
		<s:if test="${idContract.status}=='NEW'">
			<s:checkbox name="selectedContracts"
fieldValue="${idContract.id}"/>
		</s:if>
		<s:else>
			&nbsp;${idContract.status}&nbsp;
		</s:else>
	</display:column>
	<display:column 	property="number"
titleKey="label.contractNumber" />
	<display:column 	property="status"
titleKey="label.contractStatus" />
	<display:column 	property="numAuthFacilities"
titleKey="label.authFacilities" />
</display:table>

I have tried the following and do not seem to be able to get any of them
to work:
"${idContract.status}=='NEW'"
'${idContract.status}=="NEW"'
"%{idContract.status}=='NEW'"
"${idContract.status=='NEW'}"
"%{idContract.status=='NEW'}"
"idContract.status=='NEW'"
"#idContract.status=='NEW'"

And a host of others that I cannot recall.

Does anyone happen to know the correct syntax?  I am getting tired of
guessing and cannot seem to make rhyme or reason out of the syntax rules
:-)

Thanks in advance!

I will give that a try.  I am sure it will work.  Thank you so much for
your clear and detailed response.  I now not only know what to do, but
more importantly why it needs to be done that way. Thank you!

The problem is that displaytag places the current row in the pageContext
but none of your expressions are addressing it.

I tend to just use JSTL within displaytag tables as its much easier to
access the current row.
I also tend to add getters to my bean to simplify the expressions
instead of hardcoding it in the JSP. eg. isNew()

Anyway, this is a struts2 way to access it:

<display:table id="idContract" name="contracts" class="results">
   <s:set name="rowIdContact" value="#attr.idContract"/>
      <display:column titleKey="label.select">
	<s:if test="#rowIdContact.equals('NEW')">
         	<s:checkbox name="selectedContracts"

etc. 
The main point of that is that the idContact row is accessed via #attr

But this is my preferred way:

<display:table id="idContract" name="contracts" class="results">
   <display:column titleKey="label.select">
      <c:if test="idContract.new">
       	<s:checkbox name="selectedContracts"

where isNew() is property of the row class.

These close the OGNL expression too early.

As long as your action exposes 'idContract'
JavaBean-ily and the contract does the same for
'status' then

test="%{idContract.status == 'NEW'}"

should work (and you may not need the %{} bits; I
don't recall for this tag attribute).
