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

[JBoss jBPM] - Copy a ProcessDefinition from one Database to another
by eddie_84
In our project we use several different databases to store ProcessDefinitions, and we are now looking for a way to load a ProcessDefinition from database A and store it in database B. We first tried to simply pass it like this:
| // get the target jbpm context
| JbpmContext j = getTargetJbpmContext();
|
| // load process definitions
| processDefinitions = getJbpmContext().getGraphSession().findLatestProcessDefinitions();
|
| processMap = new HashMap();
|
| // deploy process definitions
| for(Iterator iter = processDefinitions.iterator(); iter.hasNext();){
| ProcessDefinition pd = (ProcessDefinition)iter.next();
| j.deployProcessDefinition(pd);
| }
|
This does not work because hibernate throws this:
org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions
We also tried to serialize and deserialize the object and load the deserialized object in the db, but due to hibernates internal way to store objects on a database this also does not really work, because it inserts a child before a parent what results in a db error because of the RI. This would be avoidable by running the RI-Check only at commit, but that would affect in several dependencies so we couldn't change that.
We also tried to clone the object using the SerializationHelper class, but due to hibernates lazy loading this didn't clone the hole object because not everything was loaded.
We also couldn't use the xml-description of the processDefinition and parse it again, because if we have to keep them we have a lot of redundant data.
so is there a way to copy a processDefinition from one database to another?
thanks in advance
