List Box Limitations?

Question

I'm using Acrobat Pro 8 on a Mac Leopard OS
Is there a limit as to how many entries a list box can hold?
I'll probably end up with about 150 entries as part of a medical history form and the list box would repeat with each recordset.
Ideally, once I learn more, I'd like the recordset to repeat with unique fields as the user requires.

Answer 1

They used to say the limit was quite low, someting less than 100, but it wasn't enforced by the user interface like you're describing, at least on Windows. I seem to recall it involved a performance issue with older Macs.
Anyway, as a test, try setting up a button and place the following code in the Mouse Up event:
var f1 = getField("list1");
var array1 = [];
for (var i = 0; i < 1000; i++) {
array1[i] = "This is item " + i;
f1.clearItems();
f1.setItems(array1);
Where "list1" is the name of a list box on your form. For me with Acrobat 9 in WinXP, this loads all 1000 items. The UI acts a bit weird when I try to edit any of the items, however.
So, a solution may be to use JavaScript to load the values. You can also use an FDF file for this, which is what I often do.
