[jira] [Commented] (ISIS-431) A boolean atribute should never be mandatory

["Dan Haywood (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ISIS-431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13679442#comment-13679442 ] 

Dan Haywood commented on ISIS-431:
----------------------------------

The workaround is to declare the type as Boolean, annotate @Optional, and use (val != null && val.booleanValue()) to determine if true:

void foo(@Optional Boolean flag) {
    setFoo(flag !=null && flag.booleanValue());
}

> A boolean attribute only has two states and when the @Optional annotation is omitted and the boolean is set to false, eg the checkbox is empty, it's impossible to save the object.
