Interator values not showed
Hi,
i'm trying the append tag and the list values of the appended lists are not
showed.
This is the main part of the jsp code:
<s:append var="metalBands">
<s:param value="%{groups}"/>
<s:param value="%{groups1}"/>
</s:append>
Total Bands:<br>
<s:iterator id="band" value="%{#metalBands}">
Band: <s:property value="#band.name"/><br>
</s:iterator>
This is my Action class:
package struts2.action;
import java.util.ArrayList;
import com.opensymphony.xwork2.ActionSupport;
public class IteratorAction extends ActionSupport {
ArrayList<Band> groups=new ArrayList<Band>();
ArrayList<Band> groups1=new ArrayList<Band>();
public String greeting(){
return "Hi, Every body";
}
@Override
public String execute() throws Exception {
this.groups.add(new Band("trash","Slayer"));
this.groups.add(new Band("trash","kreator"));
this.groups.add(new Band("death","Deicide"));
this.groups.add(new Band("death","Obituary"));
this.groups1.add(new Band("heavy","Judas Priest"));
this.groups1.add(new Band("heavy","Primal Fear"));
return SUCCESS;
}
public ArrayList<Band> getGroups() {
return groups;
}
public void setGroups(ArrayList<Band> groups) {
this.groups = groups;
}
public ArrayList<Band> getGroups1() {
return groups1;
}
public void setGroups1(ArrayList<Band> groups1) {
this.groups1 = groups1;
}
}
This is my bean class:
package struts2.action;
public class Band {
private String style;
private String name;
public Band(String st,String n){
this.style=st;
this.name=n;
}
public String getStyle() {
return style;
}
public void setStyle(String style) {
this.style = style;
}
This is the ouput application:
Total Bands:
Band:
Band:
Band:
Band:
Band:
Band:
As you can see there is no values showed .
Please, can you help me with this?.
Thanks in advanced!!.

nested struts2 validation
Posted by Stephen Ince <st...@gmail.com>.
Hi,
I would like to do nested struts2 validation. I have two questions.
1) How do I specify the validation for the following field. Can some point me to some documenation for the expression validation.
<input type="text" name="searchResults[${i}].resource.name" ..
validation.xml
<validator type="expression">
<param name="expression">
searchResults.{#this.resource.name.length() > 0}.{? #this == false }.size() <= 0
</param>
<message key="resource.name.required" />
</validator>
2) Can specify a particular method for an action class.
e.g.
SearchAction-search!update-validation.xml
where
search -- is the action alias and
update -- is the method to execute in SearchAction

Thanks Alex,
but i've solved the problem.
This is my Action class:
public class IteratorAction extends ActionSupport implements ModelDriven{
private ArrayList<Band> groups=new ArrayList<Band>();
private ArrayList<Band> groups1=new ArrayList<Band>();
private Band band=new Band("","");
public String greeting(){
return "Hi, Every body";
}
@Override
public Object getModel() {
// TODO Auto-generated method stub
return null;
}
@Override
public String execute() throws Exception {
this.groups.add(new Band("trash","Slayer"));
this.groups.add(new Band("trash","kreator"));
this.groups.add(new Band("death","Deicide"));
this.groups.add(new Band("death","Obituary"));
this.groups1.add(new Band("heavy","Judas Priest"));
this.groups1.add(new Band("heavy","Primal Fear"));
return SUCCESS;
}
public ArrayList<Band> getGroups() {
return groups;
}
public void setGroups(ArrayList<Band> groups) {
this.groups = groups;
}
public ArrayList<Band> getGroups1() {
return groups1;
}
public void setGroups1(ArrayList<Band> groups1) {
this.groups1 = groups1;
}
public Band getBand() {
return band;
}
public void setBand(Band band) {
this.band = band;
}
}
And this is my jsp code:
<s:append var="metalBands">
<s:param value="%{groups}"/>
<s:param value="%{groups1}"/>
</s:append>
Total Bands:<br>
<s:iterator id="band" value="#metalBands">
Band: <s:property value="name"/><br>
</s:iterator>
Finally i used the ModelDriven interface to get the bean atributes in a
better way.
Thanks for replying.
Cheers!!.

I think you need a public getter for band.name:
public String getName() {
return name;
}
