ADF Tree Nodes Undisclose...

Question

Hi !. I have the following question about expanding or collapsing nodes...
I have my own class ("NodoMapaDeSitio") that I use as my items to render my tree; so, the method "getRowData" returns an instance of "NodoMapDeSitio". Every time I click a node, the "varStatus.rowKey" returns me something like this:
[0]
[1]
or
if I press ina subNode [1,0] [1,1]...
My question would be if it's possible to make integer vectors to build the children key's of a node in order to disclose them or undisclose them ?.
In case that, that is possible, the following method ".setDisplayRowKey" would help me to expand certain nodes... But which method would help me to callapse them ?.
Well Hope I was clear... Thankx

Hi Timo... I solved it this way... I use the varStatus to obtain the key of the node which I pressed and I checked if that key is inside the discloseRowKeySet; if it is, I remove and collapse it !. The code is as follows...
ArrayList lista = (ArrayList) this.objeto;
RowKeySet rowKeySet = arbol.getDisclosedRowKeys();
if(rowKeySet.contains(lista))
rowKeySet.remove(lista);
else
rowKeySet.add(lista);
AdfFacesContext.getCurrentInstance().addPartialTarget(this.arbol);
AdfFacesContext.getCurrentInstance().partialUpdateNotify(this.arbol);
