Infinite “Fetching Data” in ADF treeTable


In Jdeveloper 11g R2 there is a wonderful option to easily create hierarchical data presentation as tree or table tree.

All you need to do is to define View Link between two View Objects.

This is what I did, and this is how my table tree looks like


However when I expend the row, I see endless “Fetching Data” message and the component is stacked and the process is never ends


The resolution is simple. You need to define “Key Attribute” on the child View Object


After this , tree components works like a charm
