Multiple calls to belongsto assocation getter

[mford71]

Hi,
Im sure i'm probably missing something simple here (probably because im brand new to javascript), so apologies in advance....

Ext-JS 4.07

This bit of code displays a window with a form in. It calls the getter method of a 'belongsTo' association on the record - 'getDataPackage' because I need the 'carrierId' from the parent object for the form. This code works great first time, but the second time I try and display the window I get the error - 'dataPackage.get is not a function'. I know this is probably because the second time I call the getter it doesnt need to do a read, but im unsure as to how to access the cached dataPackage.

    displayEditForm: function(grid, record) {

        record.getDataPackage(function(dataPackage, operation) {

            var editView = Ext.create('SimManager.view.ui.simcontract.Form', {
                id: 'editSimContractForm',
                title: 'Edit Sim Contract',
                layout: 'fit',
                modal: true,
                selectedCarrierId: dataPackage.get('carrierId'),
                companyStore: this.getStore('Company'),
                carrierStore: this.getStore('SimCarrier'),
                dataPackageStore: this.getStore('DataPackage')
            });            
            
            var form = editView.down('form');
            form.loadRecord(record);
            editView.show;
            
        }, this);
    },

Thanks,

Mark

The model instance should be cached onto the record based on the associatedName with 'BelongsToInstance' appended. If the property isn't there then it hasn't been loaded. The getter should automatically see this cached version and return it in the callback function however.

Ok so I dont see this model instance on the first call as expected, but I do see it on the second call - SimManager.model.DataPackageBelongsToInstance

Is this a problem with the namespace stuff - does it not recognise this as being the correct instance?

Here is the model assocation declaration -
associations: [
{ type: 'belongsTo', model: 'SimManager.model.DataPackage', getterName: 'getDataPackage', foreignKey: 'dataPackageId' }
