I’ve a grid like this and if I edit the description column it throws error “java.lang.IndexOutOfBoundsException: Index: 0, Size: 0”.
It happens when there is only one matching value in the combobox filter. The combobox looks like this
The dataprovider used is
CallbackDataProvider<String, String> descDataProvider
= DataProvider.fromFilteringCallbacks(query -> {
String filter = query.getFilter().orElse("");
datastore.query(Product.TARGET)
.restrict(query.getLimit(), query.getOffset())
.stream(Product.DESCRIPTION)
.filter(s -> StringUtils.startsWithIgnoreCase(s,filter))
.forEach(s -> System.out.print(s+"\t"));
Stream<String> propertyBoxStream = datastore.query(Product.TARGET)
.restrict(query.getLimit(), query.getOffset())
.stream(Product.DESCRIPTION)
.filter(s -> StringUtils.startsWithIgnoreCase(s,filter));
// s -> s.startsWith(filter)
return propertyBoxStream;
}, query -> {
String filter = query.getFilter().orElse("");
long propertyBoxStream = datastore.query(Product.TARGET)
// .filter(Product.DESCRIPTION.startsWithIgnoreCase(filter))
// .filter(Product.DESCRIPTION.startsWithIgnoreCase(filter))
.stream(Product.DESCRIPTION)
.filter(s -> StringUtils.startsWithIgnoreCase(s,filter))
.count();
write("filter " + filter+"\t count :"+propertyBoxStream);
return (int) propertyBoxStream;
});
and the stacktrace is

I do not know what is the problem and why it fails when there is only one matching value. If you know any solution, please put in the comments below.
