Transfer data from one store to another store

[mrileyaz]

I have a FormPanel. This form triggers a JsonStore to get data from the database. The store populates a second store. The second store populates a GridPanel. Each time the form is submitted, I need the data from the first store to be added (appended) into the second store, not replace it. Currently when I refresh the grid, the resultset from the second query replaces the first.

Is there a public method for one of these objects I do not know about?

Code samples follow:


The form triggers this store. Assume baseParams maps to: form.getForm().getValues()

  var dsUsersProxy = new Ext.data.JsonStore({
      url: './?event=ajax.groupMempers.do',
              baseParams: baseParams,
              autoLoad: true,
      root: 'data',
      fields: ['displayvalue', 'rowid']
  }); 

This is the second store. Assume JReader maps to a JsonReader which has a Record.create().

  var dsUsers = new Ext.data.Store({
              reader: JReader
  }); 

This loads the data from the first store into the second store. This is where the problem is. I have used add() and insert() and both replace the existing data. There is no JS error but the data is overwritten. I have verified this with console.dir(dsUsers)

  dsUsersProxy.on('load', function(){
              var userRecords = dsUsersProxy.getRange();
              //dsUsers.add(userRecords);
              dsUsers.insert(0, userRecords);
              console.log(dsUsers.data.length);
  });

Sorry, this was supposed to go in Ext Community Forums (2.0). I will re-post there.

While this solution is not perfect, it just work

	prepareData : function(selections) {
		var data = new Array();
		
		Ext.each(selections, function(record) {
			var to = {
				advice : record.data.advice,
				name : record.data.name
			}
			data.push(to);
		}.createDelegate(this));
		
		
		var o = {
			totalCount : selections.length,
			data : data
		}
		



		// damn im stupid, this should work too instead the lines above...
		var o = {
			totalCount : selections.length,
			data : selections
		}	


		this.ds = new Ext.data.JsonStore({
			root: 'data',
			fields: [
				'advice', 
				'name'
			],
			sortInfo:{field: 'name'}
		});
		this.ds.loadData(o);					
	},

	init : function() {
		this.prepareData(otherGrid.selModel.getSelections());
	}

dsUsers.insert(dsUsers.getCount(), userRecords);
