Yes, it is the monkeys[i] property. If I delete the "age" and the select
"size", works fine

Sure!! but i've tried every advice i found in the mail-archive... and every
combinatory
of those advices ;)
How do you do in keyboardmonkey examples for not using LazyLists?
The jsp form (MonkeyTeamForm) : (very similar to nested-tutorial "monkey
with bananas")
----------------------------------------------------
<nested:form action="updateTeam">
<nested:write property="teamName"/>
[many more simple selects and texts boxes]
<nested:iterate property="monkeys">
<nested:write property="name"/>
<nested:text property="age" size="10"/>
<nested:select property="size">
<nested:options property="../sizesList"/>
</nested:select>
</nested:iterate> [if I delete "age" and "size" boxes, n.p.]
</nested:form>
-----------------------------------------------------
the involved Form Bean MonkeyTeamForm
-----------------------------------------------------
public class MonkeyTeamForm extends ValidatorForm implements Serializable{
private List monkeys = ListUtils.lazyList(new ArrayList(), new
MonkeyFactory());
private String teamName;
public void setMonkeys(Object[] newMonkeys){
// I tried too to initialize "monkeys" as a lazy list here too
for (int i = 0; i < newMonkeys.length; i++){
monkeys.add(newMonkeys[i]);
}
}
public Object[] getMonkeys(){
return monkeys.toArray();
}
public void setTeamName(String newTeamName){
teamName = newTeamName;
}
public String getTeamName(){
return teamName;
}
[many more getters and setters that works ok]
public void reset(ActionMapping mapping,
javax.servlet.http.HttpServletRequest request){
tecnologias = ListUtils.lazyList(new ArrayList(), new MonkeyFactory());
}
public void reset(){
tecnologias = ListUtils.lazyList(new ArrayList(), new MonkeyFactory());
}
}
----------------------------------------------------
The monkey class (Monkey Team contains "Monkey"s)
----------------------------------------------------
public class Monkey implements Serializable {
private String name;
private long age; [ITS A PROBLEM TO BE "LONG"?]
private String size;
public void setTeamName(String newTeamName){
teamName = newTeamName;
}
public String getTeamName(){
return teamName;
}
public void setAge(long newAge){
age = newAge;
}
public long getAge(){
return age;
}
public void setSize(String newSize){
size = newSize;
}
public String getSize(){
return size;
}
}
---------------------------------------------------
big Thank you-Thank you
