    Default Unanswered: NestedList TreeStore setData throws "can not call method indexOf of null" error

    Unanswered: NestedList TreeStore setData throws "can not call method indexOf of null" error


    I have a NestedList which I am populating dynamically. On first setData call of TreeStore, it works fine but subsequent calls to setData result into this error "can not call method indexOf of null".
