Hello!
I’m trying to set items to combobox depending on other combobox value, but I’m getting errors and it doesn’t work. If I make a new combobox every time to set items, it works, but then I also have to create a new valuechangelistener under the combobox which I’m getting the value from and that’s not the proper way.
For example:
if (combobox1.getValue().equals("1")) {
combobox2.setItems(getItemsFromFile("1.txt"));
} else if (combobox1.getValue().equals("2")) {
combobox2.setItems(getItemsFromFile("2.txt"));
}
(TypeError) : Cannot read property ‘reset’ of undefined
(TypeError) : Cannot read property ‘confirm’ of undefined
(TypeError) : Cannot read property ‘set’ of undefined
(TypeError) : Cannot read property ‘updateSize’ of undefined
While this one works:
if (combobox1.getValue().equals("1")) {
combobox2 = new Combobox<>();
combobox2.setItems(getItemsFromFile("1.txt"));
combobox2.addValueChangeListener(e-> {
});
} else if (combobox1.getValue().equals("2")) {
combobox2 = new ComboBox<>();
combobox2.setItems(getItemsFromFile("2.txt"));
combobox2.addValueChangeListener(e-> {
});
}
How it should be done? Using Vaadin 12.
