extjs - List-View reading via JSON with no keys -

i'm using sencha architect testing purposes. added list view, connected store, connected model. store configured load following json data:

{     "data": {         "blacklist":[             "word 1",             "word 2",             "word 2"         ]     } } 

every "word x" should listed list item in list view

now wanted set model. model need "field names", in case aren't present.

if i'm using following json data:

{     "data": {         "blacklist":[             {"name": "word 1"},             {"name": "word 2"},             {"name": "word 3"}         ]     } } 

and giving model field named "name", works fine.

but how set scenario, if json values have no keys define in model (as field/fieldnames)?

without knowing want result aught able modify code looking for.

app.js

ext.loader.setconfig({     enabled : true });   ext.application({     name : ('sf' || 'senchafiddle'),      models : ['testmodel'],      stores : ['testdata'],      launch : function() {         ext.create('ext.dataview.list', {             fullscreen : true,              model : 'testmodel',              store : 'testdata',              itemtpl : "{blacklist}"         });     } }); 

model:

ext.define('sf.model.testmodel', {     extend : 'ext.data.model',      config : {         fields : [{             name : 'blacklist',             type : 'string',              // **this parse out values of 'blacklist'**              convert : function(value, record) {                 console.log("value: ", value.length);                 console.log("record: ", record);                  var returnarr = [];                 if (value && value.length > 0) {                     (var i=0; i<value.length; i++) {                         returnarr[i] = value[i];                     }                      return returnarr;                 };                  return "could not convert";             }         }]     } }); 

store:

ext.define('sf.store.testdata', {     extend : 'ext.data.store',      config : {         model : 'sf.model.testmodel',          data : [{             "blacklist":[                 "word 1",                 "word 2",                 "word 2"             ]         }],     } }); 

please let me know if missed in question,

good luck, brad
