Replacement of methode expandContext on Row binding?

[sdkwizard]

In a recent project we used the sap.ui.table.TreeTable under DS 1.6 SP1. To expand specific nodes before the table is rendered, we used the methode "expandContext" on the JSONTreeBinding, calling tableObject.getBindingInfo("rows").binding.expandContext(context);
A few weeks ago, DS was updated on SP4. The function above seems to have disapperead completely.

Is there any replacement for this function? Any other way to achieve the described goal of expanding nodes before the table is rendered??
