Subject RE: [S2] Pre-populating Checkboxes
Date Tue, 01 Jul 2008 16:33:04 GMT
This is exactly what I needed.  I was avoiding checkboxlist because I
wanted the options to be displayed vertically, but it looks to be the
only option unless I add more code to determine if a checkbox was
selected.

Thank you, everyone, for your help!!!

Hi,

I have done it like this.

// code in my action

    private String[] skill;

    public String[] getSkill() {
        return skill;
    }

    public void setSkill(String[] skill) {
        this.skill = skill;
    }

    public void prepare() throws Exception {
        skills = new ArrayList();
        skills.add("Java");
        skills.add("C#");
        skills.add("Spring");
        skills.add("Struts 2");

        skill = new String [2];

        skill[0] = "Java";
        skill[1] = "Spring";
    }
//jsp

<s:checkboxlist name="skill" list="skills"/>

Java and Spring check boxes will be selected.

Thanks,

Nuwan
