Subject [jira] [Commented] (WW-1534) The value of checkbox getted in server-side is "false" when no any checkbox been selected.
Date Fri, 02 Jun 2017 06:24:05 GMT

    [ https://issues.apache.org/jira/browse/WW-1534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16034208#comment-16034208

Aleksandr Mashchenko commented on WW-1534:
------------------------------------------

The `uncheckedValue` in [CheckboxInterceptor|https://github.com/apache/struts/blob/master/core/src/main/java/org/apache/struts2/interceptor/CheckboxInterceptor.java#L58]
can be used to set the default value. But I don't think it can be set to {{null}} right now.

[~mars_pb] Another hack is to add just hidden fields :) -> [Single checkbox generated with
iterator not working while it is not checked|https://stackoverflow.com/q/16460923/1700321]

> 	public void setRoleId(String[] roleId) {
> 		this.roleId = roleId;
> 	}
> .....
> {code}
> the retrieved value of  "roleId" is {{false}}  when user doesn't select any checkbox
elements.  In my opinion, this case should returns null directly.
