string concatenation within an EL conditional
Hello,
This may fall under nested EL expressions, which to my understanding are
intentionally disallowed, but I was wondering if there was EL syntax that
would support what I am trying to do, namely, set a URL based on a
conditional, or if I should stick with <s:if>.
Currently I have
<s:if test="mn == #m.name">
<a href="#landing">${m.dispName}</a>
</s:if>
<s:else>
<a href="/internal!m?cName=${cName}&mName=${m.name}">${m.dispName}</a>
</s:else>
but would like to do it in a single line, something like
<a href="${mn == m.name ? '#landing' : '/internal!m?cName=' + cName +
'&mName=' + m.name}">${m.dispName}</a>
Is this possible?
Thanks,
~~Scott

I don't know if it works and/or it what you're looking for, but it
worths at least a try:
<s:a action="internal" namespace="/">
<s:if test="mn != #m.name">
<s:param name="cName" value="${cName}"/>
</s:if>
${m.dispName}
</s:a>
Please let me know if it works.

Yuck; unreadable. Stick it in a custom tag where it belongs. That much
computation doesn't belong in the mainline JSP.
Does the one-liner version not work?
