I tried to report a bug in vaadin bug tracker and I am fed up.
I will post the bug here. If you guys are intrested look else just ****
Vaadin doesn’t has the professionalism of an open source product.
Component : Combobox, Container : IndexedContainer
Null selection allowed
Steps :
- populate combobox
- select an item in combobox
- call ComboBox.clear() or Combobox.select( ComboBox.getNullSelectionItemId() ) from any other Components(say another combobox) event
Throws nullpointer Exception
While calling clear combobox, combobox was disabled
Stacktrace :
com.vaadin.event.ListenerMethod$MethodException: Invocation of method valueChange in com.company.webApp.ui.viewImpl.SearchViewImpl$5 failed.
