Usage of html:checkbox for Multiple Entities

[sreenath reddy]

Hi

I have a scenario in which there are multiple checkboxes in the same page belonging to one logical entity(Say Hobbies with multiple options given to choose in the form of Checkbox Group).

Now in my ActionForm(Bean)i am using one get and set method with String[] as dataType.

So when the user selects multiple hobbies and clicks Submit, values gets filled properly . But during the modification scenario (like i set the hobbies to the form bean), the appropriate hobbies are not getting selected automatically though i used html:checkbox tag.

Is it that checkbox tag is not handling for Array of Values ??

the default html:checkbox struts tag likes to work with a single string property.
for many checkboxes, such as dynamic list of things, use html:multibox

here is a handy example i had,
my jsp:

    for (Iterator it = mgr.getItemNames().iterator(); it.hasNext()  :wink:  {
// what ever your iterator and list of name / values are
        Profile p = mgr.getProfile((String)it.next());
    %>
    <tr bgcolor="#cccccc">
        <td valign="top"><html:multibox property="items" value="<%=p.getSessionIdentifier()%>"/>
    </tr>
    <%
    }
    %>

then the form:

public class ProfileManagerForm extends ActionForm implements java.io.Serializable {
 
    String[] items;
 
    public void reset(ActionMapping mapping, HttpServletRequest request) {
        items = null;
    }
 
    public void setItems(String[] v)    { items = v;    }
    public String[] getItems()          { return items; }
}
