selectmanylistbox

How can I create a JSF composite component that binds a Collection to both an h:selectOneMenu and h:selectManyListbox?

I'm trying to create a composite component that will allow the user to toggle between a h:singleSelectMenu and h:selectManyListbox. I have it working sort of. It works as long as the value field points to a Collection...it does NOT work if the value field is null. singleMultiSelect.xhtml <?xml version="1.0" encoding="US-ASCII"?> <!DOCTYPE html> <ui:composition xmlns:f="http://xmlns.jcp.org/jsf/core" xmlns:h="http://xmlns.jcp.org/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:cc="http://java.sun.com/jsf/composite" xmlns:c="http://java.sun.com/jstl/core" xmlns:ace="http://www

How to get all the selected values from selectManyListbox / selectManyMenu / selectManyCheckbox?

How do I collect all selected values from UISelectMany components such as h:selectManyListbox, h:selectManyMenu, h:selectManyCheckbox, p:selectManyListbox, p:selectManyMenu, p:selectManyCheckbox, etc in backing bean? If someone can help with an example, that would really help.
