rawData undefined for first POST action ExtJS -

i trying fill form server response data obtained whenever click on name in grid. part, have succeeded in doing this. however, reason, first time click on name in grid, "undefine" store.proxy.reader.rawdata. doesn't matter name click first, this. subsequent clicks return expected json string. using firebug me solve problem.

the following code store 'persons' make ajax request:

ext.define('cx.store.persons', {     extend: 'ext.data.store',      model: 'cx.model.personm',     autoload: false,     proxy:     {         type: 'ajax',         actionmethods: {             update:'post'         },         url: '.../censusxphp/app/store/getuseridinfo.php',         reader:          {             type: 'json'         }         } }); 

the following function within controller above store loaded.

showmess: function(grid,record)     {         var tempid = record.get('transid');                         //grab translation id         var name = record.get('fname') + ' ' + record.get('lname'); //grab name of current user         var store = this.getpersonsstore();         store.load(         {             params:{cid:tempid}         })                         var info = store.data;         console.log(info)         console.log(store.proxy.reader.rawdata)     } }; 

i printing 2 things console: store.data object , store.proxy.reader.rawdata. printout below shows post , console print statements first 2 click events:

> post http:app/store/getuseridinfo.php?_dc=1339179358498   > object { items=[0], map={...}, keys=[0], more...} >  > post http:/app/store/getuseridinfo.php?_dc=1339179359680   > object { items=[1], map={...}, keys=[1], more...} object { id="123", bday="1/5/89", paypref="credit", more...} 

i clicked on same name both times. can see, store.data object says has 0 items during first click , rawdata "undefine; however, when expand information store.data object first click can see there indeed item json string (it same info second click item because clicked on same name twice). printout below shows this:

> $classname    "ext.util.mixedcollection"    >.     >.      >.            >   -items: [object {internalid="123", raw={...}, data={...}, more...}]          >   --0: object {internalid="123", raw={...}, data={...}, more...}   >   ---$classname: "cx.model.personm"        >   ---$inheritablestatics: ["setproxy","getproxy", "load"]  >   ---alternateclassname: "ext.data.record"     >   ---associations: object { items=[0], map={...}, keys=[0], more...}   >   ---onfig: object {}          >   ---data: object { bday="1/5/89", street="123 main st", city="los angeles", more...}          >   ---defaultproxytype: "ajax"      >   ---dirty:           false        >   ---editing:         false    >.    >.    >.   

i have no idea what's going on. have been working extjs 2 weeks difficult me see subtle errors (or glaring ones ). please point me in right direction?

thanks help! -k

store.load method asynchronous, after call starts load data , returns control. when invoke showmess first time, rawdata undefined, because data not yet loaded @ point. each call displays result previous request. use load event example:

showmess: function(grid,record) {     var tempid = record.get('transid');                         //grab translation id     var name = record.get('fname') + ' ' + record.get('lname'); //grab name of current user     var store = this.getpersonsstore();     store.load(     {         params:{cid:tempid}     });                  store.on('load', function() {         var info = store.data;         console.log(info);         console.log(store.proxy.reader.rawdata);     }, this, { single: true }); }
