Question

This is my code in jsp:

<s:iterator value="sources" status="sourceStatus">
  <s:property value="sourcesCheck"/>
  <s:property value="#sourceStatus.index"/>
  <s:if test="%{sourcesCheck.contains(#sourceStatus.index)}">
    true
  </s:if>
  <s:else>
    false
  </s:else>
</s:iterator>

sourcesCheck is an array I pass from my action populated with values 0,1,2,3,4,5. The results on my jsp show 0,1,2,3,4,5 for sourcesCheck, however, the test is always false. Why? I have tried with both int and String values for sourcesCheck. How does contains work? If index is not a String or int, what is it?

Use this code:

        <s:iterator value="sources" status="sourceStatus">
            <s:property value="sourcesCheck"/>
            <s:property value="#sourceStatus.index"/>
            <s:if test="%{#sourceStatus.index in sourcesCheck}">
                true
            </s:if>
            <s:else>
                false
            </s:else>
        </s:iterator>
