Display tag-Pagination result not working properly.

[Vic Hood]

Hi Folks
Im trying to implement pagination in my program and using the display tag library for it .I have a form in my page along with a drop down box, I expect to retain the selection in my dropdown box as i select other pages from my paginated result set. However when i click on the next page or 2 nd page of my result set , it displays that there are no records to display(probably the list holding the result set is being set to empty ) and the value of the selection in the dropdown is also reset to the default value.Any clue as to why this is happening?
This is the snippet where I try to implement it .

<display:table name="${domList}" pagesize="4" id ="dl" export="true" >     // is domList being set to null here when I click on the next page?
       <display:column property="code" sortable="true"/>     
       <display:column property="description" sortable="true" />    
       <display:column  property="statusActive" sortable="true" title="IsActive?"/>   
       <display:column  property="statusEdit" title="IsEdit?" sortable="true"/>  
      
       	<display:column title="Edit" media="html">  
       <c:set var="id" value="${dl.objid}" />  
        <a href="POC.jsp?${id}" onclick="selectobjID(${id})">Edit </a>   
    	</display:column>  
 	 <display:setProperty name="export.pdf.filename" value="POC.pdf"/>
	<display:setProperty name="export.excel.filename" value="POC.xls"/>
	<display:setProperty name="export.csv.filename" value="POC.txt"/>
	<display:setProperty name="export.pdf" value="true" /> 
	<display:setProperty name="export.excel" value="true" /> 
	<display:setProperty name="export.xml" value="false" /> 
	<display:setProperty name="export.csv" value="true" /> 

          </display:table>
