No tree element available ot row key not set.. while expand
Hi All ,
I want to expand a node from out side tree(fpr example data table)
When i programatically expanding tree node by creating ListRowKey
I am getting No tree element available ot row key not set..
But I am able to expnadAll and collapse All....
Here is sample application(sorry for Typo errors if any, i typed all the conent, I cannot copy the code from my system)..
I tried the following inputs :
2
2:3
2:3:4
It seems problem with ListRowKey,
when i give input 2:3 , when i made debug messages in UITree queueExandMethod,
getting RowKey as 2_:3(adding _)....
kindly provide any correct path for the following tree structure..
A is root node id:2
B, C are children to A with ids(3,4 respectively)
D is child of C with id 5...
Tthanks in advance....

I used same web.xml of demo examples at
