Greetings,
I have sent this post more almost 2 days ago without one response.
I hope it was simply lost with other posts but still worthy of attention.
Here is the original post:
I am unable to find a solution... even after searching... and waiting for
the espresso to kick in.
I have messages and would like to determine the number of messages in the
bean.
If there is more than one message format the output as a list or else just
display the message.
Unable to come up with something.
This is what I am currently using:
<logic:messagesPresent message="true">
<tr>
<td colspan="5" class="informationalMessage">
<html-el:messages id="message" message="true">
<bean: write name="message" filter="false"/><br>
</html-el:messages>
</td>
<td></td>
</tr>
<tr>
<td colspan="6" height="5"></td>
</tr>
</logic:messagesPresent>
Any ideas would be greatly appreciated !
- Glenn

Heh: even more of a hack, provided you're OK keeping with lists rather than
tables as in your original example:
<logic:messagesPresent message="true">
<c:set var="count" value="0"/>
<ul id="msgs">
<html:messages id="msg">
<c:set var="count" value="${count + 1}"/>
<li><c:out value="${msg}"/></li>
</html:messages>
</ul>
<c:if test="${count gt 1}"/>
<style>
#msgs { list-style: none; }
</style>
</c:if>
</logic:messagesPresent/>

I can't think of a way to find out how many messages are queued for
display, but you could do something like this (ugly, and untested):
<c:set var="first" value="true"/>
<c:set var="prev" value=""/>
<html:messages id="msg">
<c:if test="${not empty prev}">
<%-- 2nd or subsequent messsage --%>
<c:if test="${first}">
<%-- This is the 2nd message of N; start the list --%>
<c:set var="first" value="false"/>
<ul>
</c:if>
<%-- output previous message --%>
<li><c:out value="${prev}/></li>
</c:if>
<%-- Store current message --%>
<c:set var="prev" value="${msg}"/>
</html:messages>
<c:if test="${not empty prev}">
<%-- There was at least one message --%>
<c:if test="${first}">
<%-- There was only one message; show it --%>
<c:out value="${prev}"/>
</c:if>
<c:if test="${not first}">
<%-- There was more than one message;
output final message and end list. --%>
<li><c:out value="${prev}"/></li></ul>
</c:if>
</c:if>
