Check empty store

[Tbaseflug]

I am using the below function to check for empty store - says records is null or not an object?




var hospitalsLoad = function(value, metadata, records, rowIndex, colIndex, store) {


if(!Ext.isEmpty(records) && records.length > 0){


Hospitals.setDisabled(false);


Hospitals.setValue(Hospitals.store.getAt(0).get('i d'));


}


else{


Hospitals.setDisabled(true);}


}

the below seems to work - but is it valid/best practice?




var hospitalsLoad = function(value, metadata, records, store) {


if(this.getCount() > 0){


Hospitals.setDisabled(false);


Hospitals.setValue(this.getAt(0).get('id'));


}


else{


Hospitals.setDisabled(true);}


}

Hi,

How hospitalsLoad is using?
For check the Store just call store's getCount function (it should be greater then 0)

getCount seems to be working - via of the store itself

Hi,

Load event of the Store has another signature
load : ( Store this, Ext.data.Record[] records, Object options )
