I am implementing treetable for odata v2, Ihave three levels of node 1,2,3 and all the hierarchichal data is sent from get_entityset. After binding the entityset in view, i can see hierarchy but all the data is copied from last node(3) to all the levels and the expansion is endless. Somewhere i saw we should use operationMode : 'Client' , but still its not working.
why the data is copied from last node and properly formed hierarchy? Second question is why its endless expansion though only single batch call is sent to backend (i checked network tab).
