How can I map multiple values from select tag in Struts 2?

Question

I have a multi-selection combo in my Struts2 web application. I use the ui-multisection component. When I select and submit values \"1\" and \"2\"

Answer 1

what should I do for get all value selected ?

You should make a select tag to accept multiple options. This is done via multiple="true" in struts select tag. Then you interceptor stack is incomplete because multiselect interceptor is missing. You should add <interceptor-ref name="multiselect"/> to your interceptor stack after fileupload interceptor reference.

Answer 2

Try changing

private List<String> listIdSelected = new ArrayList<String>();

to

private List<Integer> listIdSelected = new ArrayList<Integer>();

since your Getters and Setters are like that.
