I hope someone can explain the following behaviour to me. Using the S2 taglibs and OGNL is starting to confuse me somewhat. I have a test JSP that I am accessing via the default ActionSupport class:
<[EMAIL PROTECTED] uri="http://java.sun.com/jstl/core"; prefix="c"%> <[EMAIL PROTECTED] prefix="s" uri="/struts-tags" %> <ol> <li><c:out value="${param.input == '1'}"/></li> <li><c:out value='${param.input == "1"}'/></li> <li><s:property value="#parameters.input[0] eq '1'" /></li> <li><s:property value='#parameters.input[0] eq "1"' /></li> <br /> <li><c:out value="${param.input == 'a'}"/></li> <li><c:out value='${param.input == "a"}'/></li> <li><s:property value="#parameters.input[0] eq 'a'" /></li> <li><s:property value='#parameters.input[0] eq "a"' /></li> </ol> If I call my page via "test.action?input=1". I get: 1. true 2. true 3. false 4. true 5. false 6. false 7. false 8. false Why is result 3 false? If I then call my page via "test.action?input=a". I get: 1. false 2. false 3. 4. false 5. true 6. true 7. 8. true Why are the result of 3 and 7 results now blank? I have no idea what is going on here, is this a bug? It seems to only happen when I'm evaluating against a single character. I'm guessing it is some kind of char to String comparison problem. It would feel very odd if I had to start using single quotes around my taglib attributes (I usually need double quotes for XML/XHTML attributes).
