If you want to render a grid column after a specific store is loaded you could do it the following way:
Ext.define('Shopware.apps.MyPlugin.view.list.MyPlugin', {
extend: 'Shopware.grid.Panel',
alias: 'widget.my-plugin-listing-grid',
region: 'center',
listeners: {
boxready: function()
{
var me = this;
// gettin' the store
var store = Ext.create('Shopware.apps.Base.store.Article').load();
// wait till store is loaded
store.on('load', function()
{
// get columns
var columns = me.headerCt.getGridColumns();
// iterate grid columns
Ext.each(columns, function(column, index)
{
// get specific column by dataIndex
if(column.dataIndex == 'articleId') {
column.renderer = function(value)
{
// get corresponding record from store
var record = store.findRecord('id', value);
if(record) return record.data.name;
}
me.getView().refresh();
}
});
});
}
},
...
