Getting values from a multiselect box?

[Migrated From Jforum.net]

Hi,

I'm trying to use this.request.getParameterValues("fieldname") to get the values returned by a multiple-select enabled field. For some reason, it always returns null (which should only happen if the field name does not exist). I've tried using this.request.getParameter("fieldname") to test this, and it successfully returns one of the selected values. Any ideas about why getParameterValues would fail?

Thanks,
Derek

I worked around this by creating a hidden input field and using a js function to populate its value with the selected options in the multiselect. Then i can use getParameter("fieldname") to get that single (but combined) value.

I would still like to know why getParameterValues() doesn't work, though, if anybody has any ideas.

It was supposed to work, as, for example, the mass delete of private messages (PrivateMessageAction.java) uses it. If you look at the source code, you will also see that, until version 2.1.7, JForum does not even override the method (e.g, it used the default implementation)
