Matt,
Thanks for the response. Are you saying that the getter and setter methods
will be called with an index value?
So the setter signature in my example would be: void setVerified(int index,
String value) and the setter would be void getVerified(int index) ?
Also, how do I know the list size to deal with and therefore know how to
size the string array?
Thanks, I appreciate your help.

I'd try making your form bean have a String[] for the getter/setter of
the checkbox's value and then name all the checkboxes with the same
name.

Subject: [displaytag-user] Issues with a checkbox decorator (help)
I am attempting to use a Decorator to put a checkbox in one
column of a table. I am running into a couple of issues, but
I don't know if my approach is correct.
My decorator code looks like this:
public class CheckboxDecorator extends Decorator {
public CheckboxDecorator() { super(); }
public String getNullValue() { return null; }
public String getCheckbox() {
MyBean bean = (MyBean) getObject();
StringBuffer s = new StringBuffer();
s.append("<input type=checkbox name=\"verified\" value=\"on:");
s.append(getListIndex());
s.append("\"");
boolean checked = bean.getVerified();
if (checked) {
s.append(" checked=\"true\"");
}
s.append("/>");
return s.toString();
}
}
Basically, I'm just returning an html formatted string that
contains a checkbox.
My (simplified) jsp:
<%@ taglib uri="/WEB-INF/display.tld" prefix="display" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<html:form action="/List" name="ListForm"
type="path.to.ListForm"> <display:table
width="80%"
name="elements"
scope="session"
border="1"
cellpadding="5"
pagesize="8"
export="true"
requestURI="list.do"
decorator="path.to.CheckboxDecorator">
<display:column align="center" property="checkbox" title="Verify"/>
<display:column align="center" property="ID"/>
...
</display:table>
<html:submit/>
</html:form>
And the relevant portion of the form bean:
public void setVerified(String aVerified) {
StringTokenizer s = new StringTokenizer(aVerified, ":");
String onoff = s.nextToken();
int index = Integer.parseInt(s.nextToken());
MyBean bean = (MyBean) mElements.get(index);
if (onoff.equals("on")) {
bean.setPublished(true);
}
else {
bean.setPublished(false);
}
}
The checkbox column is displaying properly. The main problem
I'm having is that when I hit the submit button, I expect the
setVerified method on the form bean to be called for each box
that is checked. This does not happen. The method is only
called for the first occurrence of a checked box. Why????
Another issue is with the Decorator.getListIndex method. I
thought this method would return the current object's index
in the complete list, but it returns the index on the current
page. Just as the getViewIndex method does. Is this a bug or
a configuration issue?
Am I completely on the wrong track in trying to get a
checkbox in a column? Has anyone successfully implemented
this? I would really appreciate some help. I've been staring
at this for quite a while now.
Thanks,
Kelly Clauson
