I think displayTag does not maintain any state. DisplayTag handles every
request and reorder the list you pass using configuration parameters as
d-16544-p=1&d-16544-s=0&d-16544-o=1.
If you want the list not to be reordered in every request I think you must
pass the list sorted and tell displaytag to not order the list.

title="Device" sortable="true" headerClass="thborder" class="thborder" />
<display:column property="group.label" title="Group"
sortable="true" headerClass="thborder" class="thborder"/>
</display:table>
This code generates the following html (not all shown);
<thead>
<tr>
<th class="thborder sortable sorted order1">
<a href="complianceDetails.do
?baseStat=Active+Users&d-16544-p=1&d-16544-s=0&d-16544-o=1">IP</a></th>
<th class="thborder sortable">
<a href="complianceDetails.do
?baseStat=Active+Users&d-16544-p=1&d-16544-s=1&d-16544-o=2">MAC</a></th>
<th class="thborder sortable">
<a
href="complianceDetails.do?baseStat=Active+Users&d-16544-p=1&d-16544-s=2&d-16544-o=2">User
Name</a></th>
<th class="thborder sortable">
<a href="complianceDetails.do
?baseStat=Active+Users&d-16544-p=1&d-16544-s=3&d-16544-o=2">Device</a></th>
<th class="thborder">Status</th>
<th class="thborder sortable">
<a href="complianceDetails.do
?baseStat=Active+Users&d-16544-p=1&d-16544-s=5&d-16544-o=2">Group</a></th></tr></thead>
OK, now for the question. Should I ignore the e.g.,
d-16544-p=1&d-16544-s=0&d-16544-o=1 paramaters in my
complianceDetails.do controller (Spring MVC)? Ignoring them causes the
collection to be rebuild again which in some cases is not appropriate. What
is the best way to not ignore them thereby returning to the jsp and having
the current (session scoped) collection sorted? I don't want to put in code
in every controller that basically looks for paramaters with names like
"d-". Would you implement a filter? How are other people handling the
sorting without rebuilding the collection.
Thanks,
