Subject [jira] [Commented] (WW-4703) NullPointerException in ActionSupport when use ModelDriven
Date Fri, 28 Oct 2016 07:12:58 GMT

    [ https://issues.apache.org/jira/browse/WW-4703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15614572#comment-15614572

Lukasz Lenart commented on WW-4703:
-----------------------------------

Like this

{code:java}
public class MyAction extends ActionSupport implements ModelDriven, SessionAware, ServletRequestAware
{
{
    private Map<String, Object> session;
    private HttpServletRequest request;
    private MyForm myForm;

    private Container container;

    @Inject
    public void setContainer(Container container) {
        this.container = container;
    }

    ....
{code}

Struts has it's own DI.
