Re: How can I do this
James
Can u give me some suggestion on the approach I should take, I was able
to at least come to this stage after 2 weeks of struggle. Now I have
some idea as how these tags work, if u can provide me alternate
approach it would be great.
Thanks

I don't recommend doing it this way, but the problem seems to be with
your
last select tag.
The previous ones had an index, the last on does not. This won't work,
as
you know.

Re: How can I do this
I am trying to build my table from the values I have in my arary.
My JSp page code looks like this
<% int j = ((Integer)
pageContext.getAttribute("i")).intValue(); %>
" />
" />
" >
Male
Female
Male
Female
Here my table is dynamic, I start with one empty row when the page loads
first, then I keep adding rows to the table and when I submit, (Lets say
b'cas of some validation errors I want to display the page again, now I
need to build the table where I am using the Logic:iterate to loop thru
my firstName array).
My Action Form(addRateForm.java) Liiks like this
private String[] FirstName=null;
private String[] sex=null;
public String[] getFirstName(){
return this.FirstName;
}
public void setFirstName(String[] newName){
FirstName = newName;
// setRow();
}
public String[] getSex(){
return sex;
}
public void setSex(String[] newSex){
sex = newSex;
}
It all woks fine when I am doing the first time
Say I added three rows and submitted, upon validation failure the page
comes back with three rows of data and a blank row.
This is the source after it builds the page
Male
Female
Male
Female
Male
Female
Now when I make some changes and resubmit
I get Null Pointer Exception
java.lang.NullPointerException
void
org.apache.commons.beanutils.PropertyUtils.setIndexedProperty(java.lang.Object,
java.lang.String, int, java.lang.Object)
PropertyUtils.java:1328
Let me know if I have to provide more info
Also I used indexed="true" but it did not work so I tried to do the way
I showed above.
Thanks

Can you explain what it is you are trying to do? (in a broader scope)
Have you looked at or used indexed fields before?
