Problems comparing strings within an iterator

I have problems comparing strings within an iterator JSP:

<s:iterator value="piecesTxt">
   <s:if test="top.equals('_')">
      <s:textfield name="solIntrod" theme="simple" size="2" maxlength="1"/>
   </s:if>
   <s:else>
      <s:property/>
   </s:else>
 </s:iterator>

piecesTxt is a List that contains: - Pieces of text. - Gaps, storing in List the String "_"

JSP displays "_" as text:

El ot _ o d _ a f _ imos a na _ egar en un _ ate.

I've tried also with:

<s:if test="top == '_'">
Including in s:iterator var="pt"
<s:if test="pt == '_'"> 
<s:if test="pt.top == '_'">
<s:if test="pt.charAt(0) == '_'">

Other iterator-text works but this does not. Any ideas? Thanks in advance.

OGNL interprets a single character within single quotes as a char, not a String.

Use double-quotes:

<s:if test='top.equals("_")'>

See Why won't the 'if' tag evaluate a one char string for details.
