Transient conversation data

bdillon Dec 3, 2007 11:19 AM

Hi,

I am using Seam with RichFaces. I am currently running into an issue where Seam tries to serialise the richfaces SelectionRange object (held on the SimpleSelection object).

Is there anyway in Seam to mark something as transient data so that it does not get serialised on the conversation ? I have tries using;

private transient SimpleSelection selection;

But still get the following exception;

java.io.NotSerializableException: org.richfaces.model.selection.SelectionRange
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081)
at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:302)
at java.util.ArrayList.writeObject(ArrayList.java:569)

Any help on this would be appreciated,

Thanks,

Brian

Post the full exception and your seam component.

What I have compoent wise is a BackingBean which contains a member variable used for maintaining common table functionality.

E.g. The backing bean;

@Name("vieworganisation")
@Scope(ScopeType.CONVERSATION)
public class ViewOrganisationBB {

//The ViewOrganisation contains a Table
private DataTableBB table;//The table displaying the data

......

The DataTable

public class DataTableBB {

List dataList;/** List of the Data to Display **/
private transient SimpleSelection selection = new SimpleSelection();

public SimpleSelection getSelection() {
return selection;
}

public void setSelection(SimpleSelection selection) {
this.selection = selection;
}

....

If i remove the declaration of the SimpleSelection above the problem goes away but obviously at that point the RichFaces table wont't work !

Thanks for your help on this,

Brian
