Apologies, tested further and it appears that also the reason for this
behaviour is caused by the jdbc --> see http://bugs.mysql.com/8564

Summary: when null value bean field is to be displayed, a previous column

Description:
The webmail application (http://p4u.ch) is sometimes serving empty subject
lines from the DB (an error unrelated to displaytag probably due to the MySQL
AESENCRYPT function).
When displayed with display-tag, unfortunately, not the zero-length-String ("")
is shown as described in
http://displaytag.sourceforge.net/tagreference-displaytag-12.html#column, about
the "nulls" attribute, but a value of a previous line.
To reproduce, register for free, create a few new mails with different subject
lines and save them as drafts.
Then, create a new mail with subject line "default secure smtp for contacts
(RFE 1186) und Outlook-smtp-" and save again. It will swallow the text (the
above-described supposed MySQL error) and the go to drafts. Instead of seeing
just an empty subject (or ". . ." we put under some conditions in this case),
you will see one of your earlier subject lines repeated?
the (struts) jsp part regarding this field reads like this:
<display:column title='Subject to edit
<img src="images/edit.png" style="border: 0;vertical-align:bottom;" alt="edit
draft message - load for sending"
title="edit draft message - load for sending"/> '
sortable="true" headerClass="sortable" >
<acronym title='<bean:write name="draftMsgList"
property="subject" filter="true"/>' > </acronym>
<html:link page="/editDraft.do" paramName="draftMsgList"
paramId="msgId" paramProperty="msgId"
title="draft message - load for sending" ><bean:write name="draftMsgList"
property="subject" filter="true"/></html:link>
</display:column>
