Double Page Load on call javascript method

Question

I have implemented a tree component(which I have the folders). When I clic on the tree I have to expand or close it, so I have implemented a javascript method on clic:
<af:tree value="#{bindings.OpcionesPadreView1.treeModel}" var="node"
rowSelection="single" id="t1"
partialTriggers=":::cbNuevCpta :::dlCfr"
selectionListener="#{pageFlowScope.GestionDocumentos.buscarDocumentos_SelectionListener}">
<af:clientListener method="expandTree" type="click"/>
<f:facet name="nodeStamp">
<af:outputText value="#{node.Gesdopcach}" id="otOpc"/>
</f:facet>
</af:tree>
<af:table value="#{bindings.ArchivosView.collectionModel}" var="row"
rows="#{bindings.ArchivosView.rangeSize}"
rowBandingInterval="0" id="tArch" shortDesc="Documentos"
partialTriggers=":::dlCfr :::cbOk ::t1"
disableColumnReordering="true"
binding="#{pageFlowScope.GestionDocumentos.tarch}">
</af:table
I also need a selectionListener on Java, because When I clic on the tree( that are folders), I have to bring the documents according to the folder selected into the table, so I have implemented this:
public void buscarDocumentos_SelectionListener(SelectionEvent selectionEvent) {
String codigoOpcion = null;
RichTree tree = (RichTree)selectionEvent.getSource();
RowKeySet rowKeySet = selectionEvent.getAddedSet();
Iterator rksIterator = rowKeySet.iterator();
while (rksIterator.hasNext()) {
List key = (List)rksIterator.next();
CollectionModel collectionModel = (CollectionModel)tree.getValue();
JUCtrlHierBinding treeBinding = (JUCtrlHierBinding)collectionModel.getWrappedData();
JUCtrlHierNodeBinding nodeBinding = treeBinding.findNodeByKeyPath(key);
Object[] atributeValues = nodeBinding.getRow().getAttributeValues();
codigoOpcion = (String)atributeValues[0];
Map params = new HashMap();
params.put("PV_CODREF",codigoOpcion);
params.put("PV_CODROL", LoginBean.getUser().getRolActual());
Map permisos = new HashMap();
permisos.put("PV_CODOPC",codigoOpcion);
permisos.put("PV_CODROL",LoginBean.getUser().getRolActual());
executeOperationBinding(EXECUTE_FILES, params);
executeOperationBinding(EXECUTE_PERMISOS, permisos);
The problem I have is that when I clic on the folder in the tree, the table is fetching the documents twice(like a doble page load). This doesn't happen when my clientListener is of type "selection", but with "selection" I have problems to close the tree.

Here is an example, let me know if it needs explanation.
Private Sub RSWVBAPage_afterPlay()
Dim doc As HTMLDocument
Set doc = RSWApp.om.GetTopDocument
doc.parentWindow.execScript "MyJavascriptFunction();", "javascript"
Set doc = Nothing
End Sub
