seam 2.1.0sp1
richfaces snap 3.3.0 > 12/19
jboss 4.2.2

backin bean

import org.richfaces.component.UIScrollableDataTable;
import org.richfaces.model.selection.SimpleSelection;
........

@Stateful
@Name("phyEditAction")
@Scope(ScopeType.CONVERSATION)
public class PhyEditAction implements PhyEditLocal{
 private SimpleSelection selection = new SimpleSelection();
 private UIScrollableDataTable stable;

...........
public SimpleSelection getSelection() {
 return selection;
 }

 public void setSelection(SimpleSelection selection) {
 this.selection = selection;
 }
 public String takeSelection() {
 this.phy = null;
 Iterator<Object> iterator = getSelection().getKeys();
 while (iterator.hasNext()){
 Object key = iterator.next();
 stable.setRowKey(key);
 if (stable.isRowAvailable() && this.phy ==null) {
 this.phy = ((Phy) stable.getRowData());
 }
 }
 selectPhy(null);
 return null;
 }

 public UIScrollableDataTable getStable() {
 return stable;
 }

 public void setStable(UIScrollableDataTable stable) {
 this.stable = stable;
 }

there is also an interface for this bean.

i have read everything i could find in the doc.. got the example code out of the trunk.. im new to creating jsf components dynamically... i must be missing something. i even tried using a UIComponent as the backing because some something i read in the doc then casting it to the scrollable table.. didnt work.

any help would be greatly appreciated.

i found something in the seam doc that is relevant.
http://docs.jboss.com/seam/2.0.1.GA/reference/en/html/conversations.html#d0e5182

so i restructured it correctly by moving the jsf bindings into an event bean

@Name("phyScroll")
@Scope(ScopeType.EVENT)
public class PhyScroll implements PhyScrollLocal{

 private SimpleSelection selection = new SimpleSelection();
 private UIScrollableDataTable stable;

 @In(required=false)
 private PhyEditLocal phyEditAction;



 public String takeSelection() {
 this.phyEditAction.setPhy(null);
..... getter and setters

the unfortunate thing is i get the same error.

has anyone actually made this work? any help greatly appreciated

Hello,

Looks like classloaders misconfiguration. Try to use UIComponent as bean property type.

[nathandennis]

thanks for the reply...

i cant say if it worked or not because i ran into the SimpleSelector exception referenced in the other new scrollabledatatable thread.
but at least my error changed.

Nathan,

What if you remove selection binding and try UIComponent?

[nathandennis]

im sorry i dont completely follow. do you mean change the datatype on the backing bean or remove the jsf selection binding completely?

it will render without the selection binding,,, but im not sure how to retrieve the selections without it. all the examples use the selection binding. I'm lost when it comes to using UIComponent.

if this is the solution can you give a simple example of how to do this or direct us to a place where we can find one?

i was going to have to find an example for scrollable datatable's binding attribute using UIComponent anyway.

thanks for the reply and any help.

Nathan,

I meant to say that you can remove selection="#{...}" from your page code if it causes issues, change property type to UIComponent and check if binding now works fine. That is just to check if that works.

Please post environment information as described in http://www.jboss.com/index.html?module=bb&op=viewtopic&t=147992

[nathandennis]

its issue has become a border line cross post... let's work out of
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=147992

since the other guy that had the issue will be watching that one as well. i will link this post on the other thread to keep track of the above code...

thanks for the response.
