Setting ListBox values?

Hi Troy--

I'm not really sure what you're trying to accomplish, but you may be

confusing the API for working with the set of possible values (Options) with

the API for getting the current value(s). ListBox, like any other field,

has getValue()/setValue() & getValues()/setValues() methods. These are the

methods used to both select the current value(s), and get the value(s)

submitted from the client. When you receive a request, you should be able

to just do this:

Object[] values = getDisplayField("mylistbox").getValues();

to get all the values of the listbox. If you know there is only one value

for a listbox, you can do this instead:

Object value = getDisplayField("mylistbox").getValue();

To set the selected value before or during display, you must set a *value*

that appears in the ListBox's associated OptionList. For example, let's say

you have an OptionList that looks like this:

Label Value

--

One 1

Two 2

Three 3

If you want to select the second item, you need to do this:

getDisplayField("mylistbox").setValue("2");

If you set the value to "Two" or something besides one of the values in the

option list, no values will be selected in the rendered page.

Does this make sense?
