TreeTable visibleRowCount

Hi All,

may be someone knows how to set an automatic adoption of visibleRowCount of the element TreeTable according to the number of rows.

In WDA it is enough to set rowCount = -1. And a number of rows will be automatically expanded according to content.

trying to make as

oXMLSchemaTable = new sap.ui.table.TreeTable({  columns: [ new sap.ui.table.Column({label: "Node", template: "name"}),             new sap.ui.table.Column({label: "Description", template: "description"}) ],  selectionMode: sap.ui.table.SelectionMode.None,  allowColumnReordering: false,  visibleRowCount: 2,   expandFirstLevel: false,  toggleOpenState: function(oEvent) {     oXMLSchemaTable.setVisibleRowCount( oXMLSchemaTable.getRows().length )   }
});

but getRows().Length is always equal to 2.

Any ideas?

Thanks in advance.

Best Regards
