                                    }
                                 ]
}

I'm trying to display the information in a DataView with useComponents: true.

I have defined a model and associated models for the store (and set rootProperty appropriately). This works well and the data is read in along with the associated data. I can display the individual fields for each record (eg: StartTime or Title), but I can't work out how to access or display the associated records (eg: Channel.CallSign or Recording.Status).

With XTemplates I can loop over the children of a "field" in a record to display that information.

How can I achieve similar with DataViews/DataItems and useComponents?
Should I be trying to create a sub-DataView for the associated records to display information from them?
If so, how do I define the dataMap to pass the store in the applyXXX method for the field?

Unfortunately tdack, I have no idea. But if you figure out something, please let me know how. It seems quite unfortunate that you can't just setStore for a child component, like you can setHtml.
