Yep, you found a bug. Have a look at line 2101 through 2120 here:
http://itext.svn.sourceforge.net/viewvc/itext/trunk/src/com/lowagie/text/pdf
/AcroFields.java?view=markup

You'll see that the function only modifies the first entry in
AcroFields.Item.[merged/widget/values]. To handle your case, it would have
to enumerate each of those arrays.

Suggestion: Write up a patched version that can replace some or all fields
with the same name, and submit it. Something like:

/***DANGER: CODE WRITTEN IN EMAIL EDITOR AHEAD***/
public boolean replacePushbuttonField(String field, PdfFormField button) {
return replacePushButtonField( field, button, 0 ); // maintain old
behavior
}
// new version, containing most of the old function
public boolean replacePushbuttonField(String field, PdfFormField button, int
replaceIndex) {
if (replaceIndex == -1) {
/*change them all*/
} else {
/* change the specified button */
}
}

 I have a PDF with two submit buttons with the same field
name.  I am using AcroField replacePushButtonField() to set the
submit URL at run time.  But it seems to replace the first submit
button only.   Is this a bug? how do I
 get around that?  I tried renaming one of the submit button to a
different name, but it seems the method renames all fields of the same name,
so that doesn't help.  The two buttons are on the same page.
