title: How to prevent closing of AutoCompleteCombobox popupmenu on SPACE key press in JavaFX
body: <p>I have created a AutoCompleteCombobox in JavaFX with the help of code mentioned on <a href="https://github.com/jesuino/javafx-combox-autocomplete/blob/master/src/main/java/org/fxapps/ComboBoxAutoComplete.java" rel="nofollow noreferrer">https://github.com/jesuino/javafx-combox-autocomplete/blob/master/src/main/java/org/fxapps/ComboBoxAutoComplete.java</a></p>
  
  <p>But issue is that combobox popup closes when user presses SPACE key. I want to continue filtering with space character and prevent popup from closing.</p>
  
  <p>I have handled all three events (key press, key release, key typed) on combobox but no solutions.
  I think it is being caused by key press event on combobox item list view.</p>
  
  <p>Bug is mentioned on <a href="https://bugs.openjdk.java.net/browse/JDK-8087549" rel="nofollow noreferrer">https://bugs.openjdk.java.net/browse/JDK-8087549</a><a href="https://bugs.openjdk.java.net/browse/JDK-8087549" rel="nofollow noreferrer">enter link description here</a></p>
  
  <p>I just want to know how can I override the event handler which handles SPACE key press.</p>
