Problem with <s:if> and string

[SomeoneHere]

Hi

I have code

<s:form action="SwitchActive" method="POST">
   <s:hidden name="isActive" value="%{isActive}" />
   <s:if test="%{#isActive=='Y'}">
      <s:submit value="ACTIVE" name="switchActiveButton" />
   </s:if>
   <s:else>
      <s:submit value="INACTIVE" name="switchActiveButton" />
   </s:else>
</s:form>

isActive is equal to 'Y' (checked in generated page), but button has value "INACTIVE". How should I compare variable with string? Google says that my way is correct, but it still doesn't work...

ok, found workaround (or just working way?)

<s:set name="isActiveVar" value="%{isActive}" />
<s:form action="SwitchActive" method="POST">
   <s:hidden name="isActive" value="%{isActive}" />
   <s:if test="%{#isActiveVar==\"Y\"}">
      <s:submit value="ACTIVE" name="switchActiveButton" />
   </s:if>
   <s:else>
      <s:submit value="INACTIVE" name="switchActiveButton" />
   </s:else>
</s:form>
