In the previous part I created a ListPicker class that extends IValuePickerData and Serializable. The hasCapability() and getSourceLabels() methods that the IValuePickerData interface requires have been implemented and just return false. In addition to the default constructor public ListPicker(), I’ve created two more: public ListPicker(List<String>) and public ListPicker(Set<String>). Because I’ve just used the generic classes

(The Value Picker itself doesn’t differentiate whether or not multiple items can be selected. That’s handled

It’s no surprise that, despite coming from a background of minimal Java in the days before XPages, I now use Java as my main language in XPages back-end coding. There are a few areas where I’ve had to put my thinking cap on to work out how to use Java correctly when mapping between components
