array from javascript to controller java in kendo ui

Question

I have a grid in kendo ui with batch editing and I need pass a array to my controller when user clicks update. I have the follow code:

index.jsp:

parameterMap: function(data, type) {
    if (type != "read") {
        data = data.models;
    }
    return data;
}

Controller.java:

@Post
@WithoutRoot
public void atualizar(List<MyClassViewModel> vm) {
    result.nothing();
}

This way, although the data.models containing an array of objects that were changed, my List returns empty. How can I do that?

Try using kendo.stringify:

parameterMap: function(data, type) {
    if (type != "read") {
        data = kendo.stringify(data.models);
    }
    return data;
}

Not sure if this will fix your issue but I'm also using batch: true for my dataSource and this seems to be working for my view models.

You probably also want to check Chrome -> Developer Tools -> Network -> Headers-> Request Payload and see how your data is handed over to the server. Your MyClassViewModel property names should match exactly what you pass from the client.
