I think the new vaadin dialog window in v14.2 has some issue. I just added one textfield into a formlayout and added it to the Dialog window. But it shows a vertical scroller like below
The code is
Dialog dialog = new Dialog(); FormLayout layout = new FormLayout(new TextField("Queue Name", mqQueue.getName(), "")); dialog.add(new H2("Queue Properties")); dialog.add(layout); dialog.open();
if you know any fix, please update in the comments.
