For some reason, our admins are seeing a memory leak on the
TransactionVO object that is in the class/jsp below. It is used in
other classes but not in a way that I would think would cause a memory
leak. It is just kept as a collection of objects retrieved from the db,
then passed through the session to displaytag for viewing, same as a
number of other objects in our application that are not causing leaks.
It is removed from the session after saving. Even if the person clicks
off the screen before saving, I just don't see how that would matter,
the session invalidates after 15 minutes and would be collected.
We are using WebSphere 5.1 on AIX, displaytag v1.1.
The only place I see this object used in a way that it is NOT used
anywhere else is in the code below, which is using a display tag class.
Has anyone else seen this problem?? Am I doing something wrong in the
class/jsp below?
------------------InsertCheckBoxDecorator-------------------------------
import org.displaytag.decorator.TableDecorator;
import com.utils.model.TransactionVO;
/**
* Decorator responsible for inserting a checkbox for every row.
*/
public class InsertCheckBoxDecorator extends TableDecorator {
/*
* Retrieves the checkbox for the row.
*
*/
public String getCustomCheckBox() {
StringBuffer buffer = new StringBuffer();
TransactionVO transaction =
(TransactionVO)getCurrentRowObject();
buffer.append("<input type=\"checkbox\" name=\""+
transaction.getTransactionId()+"\" >" );
return buffer.toString();
}
}
------------------------jsp displaytag
table------------------------------
<%List resultList = (List)
session.getAttribute("searchResults"); %> <!-- list of
TransactionVOObjects -->
<display:table id="transaction" class="displaytag75"
decorator="com.utils.decorator.InsertCheckBoxDecorator"
name="<%=resultList%>" pagesize="<%=resultList.size()%>"
requestURI="/utils/doResults.do" >
<display:column property="customCheckBox" title=" " />
<display:column property="clientName" title="Client"
sortable="true" />
</display:table>
Thanks!!

Hi,
is it possible to render "display:column"s vertically? If not would it
be a good idea to extend the library in that way?
Felix
