Question

Apologies If I am asking a very dumb question.
I am trying one very simple thing.

<s:set name="tranType" value="%{'S'}" />
<s:if test="%{#tranType == 'S'}">
     blah
</s:if>

This doesn’t work and I am getting following error. Please let me know If I should attach complete stack trace. If I use more than one character in for the value then it runs fine.

java.lang.ClassCastException: java.lang.Character cannot be cast to java.lang.String

Fixed this by doing following.

<s:set name="tranType" value='%{"S"}' />
<s:if test='%{#tranType == "S"}'>
     blah
</s:if>

Converted ‘ to ” and vice-versa.
