I need to populate the options in a multiple select box dynamically from
javascript. The property that is being populated is an array of strings. I
have that set up and working with no errors, but I don't ever get anything
back in my array.
For example, say I declare
<html:form name="theForm" blah blah blah>
<html:select name="ids" type="myActionForm" multiple="true">
<!-- note the conspicuous LACK of option tags here -->
</html:select>
....more stuff here...
</html:form>
and then later on, via JavaScript, I do something like:
theForm.ids.options[theForm.ids.options.length] = new Option("Some
Value","Some Text");
I have that working, where the multiple select box is populated and changes
dynamically, but when I submit the form, I get a zero length array in
String[] property myActionForm.ids -- grrr!
I'm using Sun Studio so I can debug and trace and everything. I find that
when the ActionForm is created, it calls all the right stuff, but when the
fields get populated after the input form is submitted, all the non-multiple
select fields get handled, but it never executes the method "public void
setIds (ArrayList ids)" nor does it execute the method "public void setIds
(String[] ids)" -- I had to create both those methods to get past all the
introspection stuff.
HELP!!!!
