Yes, we experienced something similar. It only appeared under Tomcat,
Weblogic was ok. I *think* the issue is that one of the distributions
prior to display tag 1.0 contained a configuration bug. The tld did not
define sortProperty. Not sure what the spec says regarding verifying
property (attribute) definitions... Looks like Weblogic ignored the
missing field and just used normal reflection for the property.
Obviously, Tomcat is a little more strict.
Fix: We fixed the problem by getting a new/distribution - 1.0.
Problem Detail:
---------------------
Configuration at issue includes, in web.xml:
<taglib>
<taglib>
<taglib-uri>displaytag-12</taglib-uri>
<taglib-location>/WEB-INF/displaytag-12.tld</taglib-location>
</taglib>
In the tld that your web.xml references, open it up an check for the
sort property reference. It is likely missing. Here's what it should
look like:
<tag>
<name>column</name>
...
<attribute>
<name>sortProperty</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
<type>java.lang.String</type>
<description>
name of the property in the bean specified in the parent
table tag (via the "name" attribute) which will
be used to sort values in the column. This can be used
when the column body is filled or a decorator is
used and column should sort on undeorated values.
</description>
</attribute>
I mention this only because if you are using a locally built version out
of necessity, you can hack the tld to add the entry.
HTH,
Justin

Justin,
I'm not sure if you caught my post the other day, but my friend has been
getting this error on his box (running in OS X, Tomcat 5.5.4) , except
the same code works fine on mine.
javax.servlet.ServletException: /browse.jsp(53,5) Attribute sortProperty
invalid for tag column according to TLD
We're both are using displaytag-1.0. Here's the code that's calling it:
<display:table name="model.listings" class="list" requestURI=""
id="listing" export="false">
<display:column sortable="true" href="listing.html" paramId="id"
paramProperty="id"
property="shortDesc" titleKey="listing.shortDesc"/>
<display:column sortProperty="price" sortable="true" width="70"
titleKey="listing.price">
<fmt:formatNumber type="currency"
value="${listing.price}"/>
</display:column>
</display:table>
Any help would be great.
Thanks,
PJ
