I've come across the need to override a request parameter for setting
the "selected" value of a Select list (when used in conjunction with
Struts in this instance). Since I cannot req.setParameter(), I want to
use req.setAttribute(), which isn't currently supported:
===============================================================
// get the current selection
String[] selected = req.getParameterValues(name);
// begin "patch"
/* override the request parameters if an attribute is set */
if (req.getAttribute(name) != null) {
if (req.getAttribute(name) instanceof String) {
selected = new String[] { (String)req.getAttribute(name) };
}
else if (req.getAttribute(name) instanceof String[]) {
selected = (String[]) req.getAttribute(name);
}
}
// end "patch"
if (selected != null && selected.length > 1 &&
===============================================================
I've tested this code change and it works for both String and String[].
