Re: Is that a way to check or uncheck a checkbox using data binding?

Hi,
Sorry for this late answer.
This is the more generic helper that I use on different windows :
private static class CheckboxMapping implements Button.ButtonDataBindMapping {
        private final Set> set; 
        private final Checkbox cb;        
        private final Key key;
        
        public CheckboxMapping(Checkbox cb, Key key, Set> set) {
            this.cb = cb;
            this.key = key;
            this.set = set;
        }

        @Override
        public Object toButtonData(Object value) {
            if (value != null && ((List>) value).contains(key))
                cb.setSelected(true);
            else 
                cb.setSelected(false);
            return cb.getButtonData();
        }

        @Override
        public Object valueOf(Object buttonData) {
            if (cb.isSelected())
                set.add(this.key);
            return new ArrayList>(set);
        }
        
    }

I have to learn what a "JIRA issue" is, I am new to open source (I come from 
.Net). So I think nothing about this.

Bye...
