In case you missed to see this in the docs... See the Struts doc:
Building View Components and See in Struts Validator.
Note: If your required form property is one of the Java object
representations of primitive types (ie. java.lang.Integer), you must set
the ActionServlet's *convertNull* init parameter to true. Failing to do
this will result in the required validation not being performed on that
field because it will default to zero

Hello homas,
To avoid this problem, I use String type in my getter/setter in my Struts
form for any type (Integer, Date,...).
So, you could do that :
public class User {
String age;
public String getAge(){
return age;
}
public void setAge(String age){
this.age=age;
}
}
After you must convert String age into Integer age in your action struts
(after validation), to get values of list of ages.

Hello,
I have the following problem.
I have an struts form with an Collection getter and want to let set
struts the input values of an submit.
public class UserForm extends ActionForm {
// returns a collection of user beans
Collection getUsers(){
...
}
}
public class User {
Integer age;
public Integer getAge(){
return age;
}
public void setAge(Integer age){
this.age=age;
}
}
In the jsp- Page I use layout:collection with layout:text to show the
input fields in a table.
<layout:form action="/save">
<layout:collection property="users" indexId="index">
<layout:collectionItem title="Age" >
<layout:text property="users[${index}].age"
layout="false"/>
</layout:collectionItem>
</layout:collection>
</layout:form>
On submit struts fill also all values in the user bean, but struts set
"0" into the age-Field and not "null" if the value is empty.
How can I modify this?
Regards
Tom
