    @pike Good 🙂 I'll be gone for a few hours, let me know if you run into trouble 🙂

    yeah I'm just not seeing how to wrap the jsonmodel so I can update it

    @edvin giving up for now .. it's just gonna be local vars I suppose.

    @edvin You should link your YouTube channel in the docs. I discovered it yesterday and I learned A LOT, really good material!

    Hey guys, I need some help with 
    dataGrid
    . I have it bound to an 
    observableList
    that I edit, so the changes to this list should be reflected in the 
    dataGrid
    , but they don't. When I use a 
    listView
    for example, it DOES work. 🤔 Fun fact: I've edited the 
    DataGridTest
    to bind data just like I do, and it works there. I'm confused.

    It's a problem with 
    cellCache
    . I've switched back to 
    cellFormat
    , now it works.

    Found the problem! I was using a list of 
    data class xyz
    that contains 3 properties and has no 
    hashCode
    implementation, and for some reason this made the 
    cellCache
    bug out. Might want to investigate this. Fixed by overriding the 
    hashCode
    and returning 
    identityHashCode
    . I don't know how the 
    property.hashCode
    is implemented, can't find it in the sources.

    @pim This is how cellCache works, it specifically says in the docs that you need to provide meaningful equals/hashCode to use cellCache 🙂

    I don't really like cellCache, I think it should mostly be avoided. I'll add cellFragment support to DataGrid as well.

    @pim Good call, we should add a link to the YouTube channel in the guide. I'm thinking about doing another screencast about the cellFragment support for tableview soon.

    My house is a war zone right now, carpenters everywhere, so it's hard to concentrate, will try to get it done towards the weekend.

    I'd be grateful if as many as possible can test the TableView changes I made yesterday. Hopefully everything works exactly as before, and all tests pass, but I'm always a bit anxious when I change things around a lot.

    @edvin I'm implementing ItemViewModels in my app. I have a model with a 
    ListProperty
    , but it seems this does not get initialized as an empty list when the 
    item
    is null, is that correct?

    java.lang.IllegalStateException: displayModel.machines must not be null

    @pim I think that's by design, can't double check right now though! Will get back to you.

    val machinesProperty = bind(autocommit = true) { item?.machinesProperty }
    is what I'm doing.

    In the source I see 
    is ObservableList<*> -> if (value != null) SimpleListProperty(this, prop.name, value as ObservableList<T>) else SimpleListProperty(this, prop?.name)
    so..

    @edvin About 
    cellCache
    and hashCode -> I thought a data class would solve the problem but I guess property.hashCode doesn't do the job

    @pim I thought so too actually. But if you have a data class with mutable properties it would fail for sure. Best to add a meaningful one yourself.

    @edvin I did, using my own hashCode library 🙂

    That's a good idea, and I'm designing the new version of the PCB. I do like the volume wheel on the Das Keyboard 😁

    @edvin re: yesterday, could you point me at doc for how to bind between the view and controller for this? I feel like I'm going in circles. I tried basing it off this: https://edvin.town/tornadofx-runasync-with-taskstatus/

    @pike Sorry, I'm all out of time today. My workload is just increasing these days, feel like I'm drowning. Hopefully some of the other guys can pick up the slack, I'm back as soon as possible 🙂

    @pike Well I am not @edvin but I will give it a shot. I have taken your Datamodel and simplified it a bit. I basically inejected the MonthlySalesResponseModel into the View and the Controller. The controller can then update the ViewModel. The View binds to the viewmodel so if later on a new MonthlySalesResponse object would be set, the ViewModel is taking care of rebinding the properties.
