I have a button (com.sencha.gxt.widget.core.client.button.TextButton), added to the toolbar (com.sencha.gxt.widget.core.client.toolbar.ToolBar). When you click on one of them, there is a transition to another point of the tree. However, when you return to the previous point is that the left button is selected. When you click on the next button is similar to the transition to another point of the tree. When returning the two buttons are already selected ('to Products', 'to Statements').
