I have created a tree grid with three level…First two level are working fine but third level is behaving differently.

When Tree grid got loaded, level “2” rows are by default remain expended. here is sample data and I am using jason in a php file.

{“page”:null,”total”:0,”records”:”69″,”rows”:[
{“id”:0,”cell”:{“Record_id”:”1674″,”Requestor”:”jreynen”,”Record”:”L2_TEST_BATCH”,”Status”:”FAILED”,”level”:”0″,”parent”:”NULL”,”isLeaf”:”false”,”expanded”:”false”}}
,{“id”:1,”cell”:{“Record_id”:”15593″,”Requestor”:”jreynen”,”Record”:”L2_SWITCHING”,”Status”:”FAILED”,”level”:”1″,”parent”:”0″,”isLeaf”:”false”,”expanded”:”false”}}
,{“id”:2,”cell”:{“Record_id”:”159400″,”Requestor”:”jreynen”,”Record”:”L2_switchingSupport_TC”,”Status”:”FAILED”,”level”:”2″,”parent”:1,”isLeaf”:”true”,”expanded”:”false”}}
,{“id”:3,”cell”:{“Record_id”:”159412″,”Requestor”:”jreynen”,”Record”:”L2_switchingSupport_TC1″,”Status”:”FAILED”,”level”:”2″,”parent”:1,”isLeaf”:”true”,”expanded”:”false”}}
