RE: How to handle multiploe unknown form fields
I didn't realize that Struts could actually pass a pre-filled ArrayList.
That's pretty cool.The way that I've done index properties in Struts
call this method in my version:
Myproperty(int index, String value);
In that method, you can recreate whatever you want however you prefer.
This is a good reference for you to use -->
http://struts.apache.org/faqs/indexedprops.html
You also can use regular struts html tags to create the indexed values
for you by using the indexed=true property instead of hand-writing out
the name values as in the example below. I use indexed properties to
recreate lists as well as objects in lists by tricking struts into doing
the right thing so the below will work. It may just be that I have not
explained it clearly if it doesn't work for you.
Hope it helps you.

Subject: Re: How to handle multiploe unknown form fields
In fact it did help because it answered some question for me. I spent
the last hour searching for the RIGHT answer... This looked like it, but
for whatever reason it would never work for me when I tried to do the
exact same thing in my own project. So, I went ahead and hacked
together my own solution...
In my test JSP, I have the following:
Then in my ActionForm, I have:
private ArrayList skills = new ArrayList();
public ArrayList getSkills() {
this.skills.add(new String(""));
return this.skills;
}
public void setSkills(ArrayList skills) {
this.skills = skills;
}
public ArrayList getSkillsClean() {
for (Iterator it = this.skills.iterator(); it.hasNext();) {
String s = (String)it.next();
if (s.trim().equalsIgnoreCase("")) {
it.remove();
}
}
return this.skills;
}
Struts knows that it's an indexed property and knows how to populate the
ActionForm. The problem I found is that you either have to (a) have an
initial capacity for the ArrayList and more importantly you must
initialize all the elements because the getSkills() method is called for
each element that is added. So, instead, I add an element in
getSkills() myself. The problem is, if you then later call getSkills()
from the Action, as one would expect to do, you'll always have an empty
element at the end (or more, if you happen to call the method more than
once). No big deal, but I decided I didn't like it, so I added the
getSkillsClean() method, which removes the empty elements.
I don't think I'm doing this the right way, and indeed the link you sent
shows a more elegant solution, but as I said it wouldn't work for me
when I tried, and I like things that work (I'm odd that way!), and this
has that virtue, so I'm happy.

Re: How to handle multiploe unknown form fields
That will take care of the presentation side, true enough. But the problem I'm still trying to solve is how to deal with all the parameters when the form submission happens. For instance, let's say I dynamically construct names for each drop-down along the lines of "dropdown" where is the skillID from the database... Since the number of skills could vary, it's not practical to have a getter/setter pair for each. So, logically, I'd want to use a collection, maybe an ArrayList for instance. However, somewhere along the line, some code has to realize "gee, all of these parameters that were submitted are related in a sense and need to be stuffed into this ArrayList over here". So, what will do that? Is there anything in Struts to do it now? If not, where do I need to write the code to do this? That's really the crux of my problem. Another posted mentioend the taglibs can construct such a name on the JSP side, and that's cool (except that I scorn the use of taglibs, but I could probably bring myself to do so here). That still, as far as I can see, doesn't answer how this variable list of parameters gets put into the ActionForm. -- Frank W.
