Autocomplete combo future problem

The returned xml of the source jsp page is

<?xml version="1.0" encoding="UTF-8"? > 1 2 . . I am using dhtmlxGrid2.6.But still it is not working. Please tell me what's the problem. Thanks.

Above snippet looks valid
Beware that combo will show only options which conform entered text, so if you have typed “a” and return “aa”,“ab”,“bb” results - only “aa” and “ab” will be show, as “bb” doesn’t match for already entered “a”
