your content variable anchorpane, line
((pane) content.getchildren()).getchildren(); is wrong, since content.getchildren() returns child list (observablelist<node>) , cannot cast pane.
the vbox fx:id="sidemenuvbox" child of anchorpane. can as
vbox vb = (vbox) content.getchildren().get(0); then can button children of vbox by
vb.getchildren(); however, controls in fxml file have fx:id attribute defined. can directly inject , access them these ids. more info, research on fx:id used for.
