I'm trying to clear the user selected value on a IPickTreeItem. This is the only solution I've found to restrict the user from selecting some of the Tree root values (not all). To be more clear, it seems that calling event.cancel() do not stop the event from bubbling. Am I doing something wrong ? <pre><code>TreeNode treenode = new TreeNode("root", new TreeNode("Operation A"), new TreeNode("Operation B")); final DynamicForm dynamicForm = new DynamicForm(); Tree tree = new Tree(); tree.setRoot(treenode); final IPickTreeItem pickTreeItem = new IPickTreeItem(); pickTreeItem.setValueTree(tree); pickTreeItem.addChangeHandler(new ChangeHandler() { @Override public void onChange(ChangeEvent event) { pickTreeItem.clearValue() // Not clearing the value pickTreeItem.setValue((String)null) // Not working neither event.cancel() // Not seeming to work... } }); dynamicForm.setItems(pickTreeItem); dynamicForm.draw(); </code></pre> This is not working either : <pre><code>pickTreeItem.setInputTransformer(new FormItemInputTransformer() { @Override public Object transformInput(DynamicForm form, FormItem item, Object value, Object oldValue) { return "Desired New Value (not working)..."; } }); </code></pre> This is weird because it works using an external Button to clear the value (outside the picktreeitem handler) <pre><code>Button bt = new Button("click"); bt.addClickHandler(new ClickHandler() { @Override public void onClick(ClickEvent event) { pickTreeItem.setValue((Object) null); } }); </code></pre> <h2>Expected behavior</h2> My Tree : -aaaa ----bbbb ----cccc -dddd ----eeee ----ffff If the user selects "aaaa" the PickTreeItem value should be reverted to the defaultValue ("Choose a value"), optionally inform the user that he cannot pick "aaaa". The PickTreeItem should accept "dddd" as a valid choosen value.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
