Well, HTML never submit the "whole" content of a list AFAIK, only the
selected one. So you have a few choices:
1) Select using javascript ALL the items as Ian suggested, so they are
all submitted (but this need a select many)
2) Populate the list in the server side, so you don't need to submit
those values (your solution)
3) A trick would be to have an hidden property and having a javascript
put all the items in it on submit. Your visible control will send the
selected item, and your hidden property the while list (comma
separated?). If you use a JSF component for the hidden you will need a
binding to get the submitted value (because your using
immediate="true") or you may want to use a plain old html <input
type="hidden"> and retrieve its value using the external context. Not
very much JSF, IMO this isn't a very good solution.
4) Take solution 2 and add ajax4jsf, so you wrap the server round-trip
as an ajax request and let a4j rewrite the DOM only for your list
component.
Sometimes I hate frameworks too, but in your situation I think that
its not a framework fault at all :-). JSF allows you to solve the
problem in a clean way if you want to (solutions 2 and 4), or to go
the non-JSF tricky way (solution 1 and 3).

2006/6/20, Gregg Bolinger <[EMAIL PROTECTED]>:
And this is why I hate frameworks sometimes.
Basically what I have, as I said, is I need to be able to add keywords to a
select list from a textfield. Then, upon save/update, I need to be able to
get all the items from the select list.
To get all the items, here is what I did:
List selectItems = keywordSelect.getChildren();
Iterator iter = selectItems.iterator();
while(iter.hasNext())
{
UISelectItems items = (UISelectItems)iter.next();
List l = (List)items.getValue();
for (int i = 0; i < l.size(); i++)
{
SelectItem item = (SelectItem)l.get(i);
System.out.println(item.getLabel());
}
}
This works fine. The problem then became in how I was adding items to the
select list. Originally, I was using javascript to add items and I used a
commandButton with a type="button" and use the onclick to call the
javascript function. However, what I realized is that since the model for
the select list isn't being updated, I don't get the new values I added
using the above solution.
So what I had to do was add keywords to the select list using Java code. I
did it like so.
SelectItem item = new SelectItem(getKeyWord(), getKeyWord());
List list = keywordSelect.getChildren();
Iterator iter = list.iterator();
while(iter.hasNext())
{
UISelectItems items = (UISelectItems)iter.next();
List itemsList = (List)items.getValue();
itemsList.add(item);
items.setValue(itemsList);
}
While this works, it seems silly to me that I need to hit the server to do
this. Actually, pretty rediculous. Sure, I could incorporate some Ajax to
update the model so I wasn't having to send so much across the pipe, but
even that seems silly.
I'd still like to know if there are any alternatives.

to get a handle on the selectItems that it contains. Any other suggestions?
