javascript - Extjs - Combo with autocomplete: two types of values -


i'm trying add new criteria extjs combo autocomplete. when user enters term in text field, should suggestions, either student's name, or subject. did accomplish first case (names only). here details: extjs - combo templates display multiple values

now, should add subject criteria in autocomplete list, if user enters mat, get:

mathio,jay << student's first , last name

mark,matt << student's first , last name

mathematics << subject

here code, still not working:

listconfig: {         loadingtext: 'loading...',         tpl: ext.create('ext.xtemplate',         '<tpl for=".">',         '<tpl if="subject.length != 0"> ',         '<div class="x-boundlist-item">{subject}</div>',                                                '<tpl if="l_name.length == 0"> ',                     '<div class="x-boundlist-item">{f_name}<p><font size="1">last name: unknown </font></p></div>',     '<tpl else>',        '<div class="x-boundlist-item">{f_name}<p><font size="1">{l_name}</font></p></div>',     </p></div>',         '</tpl>',         '</tpl>'),          renderto: ext.getbody(),              },

seems if..else construction inside template definition wrong, 

tpl: ext.create('ext.xtemplate',     '<tpl for=".">',         '<tpl if="subject.length != 0"> ',             '<div class="x-boundlist-item">{subject}</div>',         '<tpl else>',                                                    '<tpl if="l_name.length == 0"> ',                              '<div class="x-boundlist-item">{f_name}<p><font size="1">last name: unknown </font></p></div>',             '<tpl else>',                 '<div class="x-boundlist-item">{f_name}<p><font size="1">{l_name}</font></p></div>',             '</tpl>',         '</tpl>',     '</tpl>'),
