primefaces - Acces Treenode using Rowkey -

i have rowkey(say 0_0,0_1,etc) of treenodes, there simple way node rowkey or need iterate on entire treenode.

the below code doesnt work

private treenode getnode(treenode node, string key) {     for(treenode child : node.getchildren()){         if(key.equals(child.getrowkey()))              return child;         return getnode(child,key);     }     return null; } 

to make short possible it's impossible node rowkey because type of informations pass jsf page been it's string 1 mean it's impossible retrieve data informations, said in question solution have loop in tree search it.
