Hi, now that all is looking fine I'm observing a strange behaviuor. The same method, to 'check/uncheck' all from a button,
public void modifyAllCheckBoxes(final boolean select) { visitChildren(CheckBox.class, new IVisitor<Component>() { @Override public Object component(Component component) { CheckBox checkBox=(CheckBox)component; checkBox.setModelObject(select); return IVisitor.CONTINUE_TRAVERSAL; } }); } seems not working when all are collapsed and if I want unselect all (the select works). 1. Collapsing all and selecting all works 2. nodes into a branch can be unselected with the button only after having expanded and collapsed it page is opened with the tree state = expanded by default best Massimo -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/wicket-tree-checkboxes-managing-tp3472967p3540207.html Sent from the Users forum mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
