Dear....
the Text Property must be exist in ActionForm as you write
Name: <html:text property="name" />
the property name exist in Father ActionForm becuse the struts framework make
corresponding between the property value in textfiled and the attribute in ActionForm
package sample;
import java.util.*;
import org.apache.actions. *;
public class Father extends ActionForm{
private String name;
private String childName;
private String childAge;
//....Getters and setters..../ /
}
************
<html:form action="fatherActio n">
Name: <html:text property="name" /><br/>
<b>Child details</b>< br/>
Only child name: <html:text
property="childName
Only child age: <html:text
property="childAge"
</html:form
************
************
If you have many child you do that in class Father
package sample;
import java.util.*;
import org.apache.actions. *;
public class Father extends ActionForm{
private String name;
private ArrayList<Child> childs;
//....Getters and setters..../ /
}
Take a values from textarea checklist and so on..........

Hello,
My previous use of Struts was on a very very simple application and I was
able to do well with it. But now I am have a more complex model which I am
not being able to get around with as I have to build a html form whose
property maps to the attribute of an attribute of the ActionForm. My doubt
relies on how to access this "sub-attribute" on teh html form?
In case this is not to clear, I have the following, very unreal scenario:
package sample;
import java.util.*;
import org.apache.actions. *;
public class Father extends ActionForm{
private String name;
private Child onlyChild;
//....Getters and setters..../ /
}
------------ --------- --------- --------- --------- ---------
package sample;
import java.util.*;
import org.apache.actions. *;
public class Child extends ActionForm{
private String name;
private int age;
//...Getters and setters...//
}
------------ --------- --------- --------- --------- --------- -
page.jsp
(...)
<html:form action="fatherActio n">
Name: <html:text property="name" /><br/>
<b>Child details</b>< br/>
Only child name: <html:text
property="onlyChild .name"/>< !--?????? ??--><br/ >
Only child age: <html:text
property="onlyChild .age"/><! ----????? ???????-- ->
</html:form>
(...)
------------ --------- --------- --------- --------- --------- -
When I try it like the example above I get error as it the
onlyChild.whatever does not exist, does no map to a known attribute it is
null.... Please let me know how to achieve that... Your help is much
appreciated. ..
Merry Xmas in advance!!!
