Hello!
I am quite baffled by the NullPointerException i get when i add
suggestions to a MultiWordSuggestOracle in order to create a
suggestion box later.
MultiWordSuggestOracle oracle = new MultiWordSuggestOracle();
List<String> suggestions = new ArrayList<String>();
for(int i = 0; i < getWidgetData().length; i++)
suggestions.add(getWidgetData()[i]);
oracle.addAll(suggestions); -> NULL POINTER EXCEPTION
Searching around, i found out that the exception is being propagated
from the following method (method that belongs to the class
com.google.gwt.user.client.ui.MultiWordSuggestOracle)
private String [Search] normalizeSuggestion(String
formattedSuggestion) {
// Formatted suggestions should already have normalized
whitespace. So we
// can skip that step.
// Lower case suggestion.
formattedSuggestion = formattedSuggestion.toLowerCase(); -> NULL
POINTER EXCEPTION
// Apply whitespace.
if (whitespaceChars != null) {
for (int i = 0; i < whitespaceChars.length; i++) {
char ignore = whitespaceChars[i];
formattedSuggestion = formattedSuggestion.replace(ignore,
WHITESPACE_CHAR);
}
}
return formattedSuggestion;
}
I have to admit i am having trouble coming up with an explanation or
solution, so any help will be most welcome and appreciated!
Thanks in advance!
Rafael
