Subject: Re: Iterate update
From: JDavids <[EMAIL PROTECTED]>
===
So I did this in bean:
public void setFstName (String[] names) {
int j = names.length;
System.out.println("XXX in set[]"+j);
for (int i=0; i<j; i++) {
System.out.println(names[j]); }
And in the html:text I did indexed="true".
In action, I printed an enumeration of properties, and the array does go
to the action!!! Great. Page/JSP tag work.
But the setFstName(String[] names) does never get called.
What would be a signature of the method that does the setter in the bean?
Thanks in advance for help.
