getO2MRecord throwing exception on model

[joseluiselp]

I'm trying to save a local column given a condition inside any of the O2M records, using the following code inside a OModel class.

@Odoo.Functional(method = "isRead", depends = {"notification_ids"}, store = true)
    OColumn is_read = new OColumn("Notification read", OVarchar.class).setLocalColumn();

 public boolean isRead(OValues values) {
        try {
            //First way to doit
            List<Integer> ints = values.toDataRow().getO2MRecord("notification_ids").getIds();
            for(Integer i : ints){
                System.out.println(i+" id notification");
            }
             //Second way to doit
            List<ODataRow> notifications = values.toDataRow().getO2MRecord("notification_ids").browseEach();
            for(ODataRow r : notifications){
                System.out.println(r.getInt("id")+" notification tal");
                System.out.println(r.getBoolean("is_read"));
.......
            
 }

Both ways are throwing a java.lang.ClassCastException: java.util.ArrayList cannot be cast to com.odoo.core.orm.OO2MRecord. I'm using the latest version of your code, also tried with childs_id inside ResPartner model and I got the same results.

Some things...

• values.toDataRow() does not actually create a record with relations. This is why I created pull request [IMP] Allow creating a ODataRow from OValues with relations based on a OModel #328 that allows passing a model instance to that method so that you can access related records.

• You are storing a OVarchar but the method is returning a boolean. This is possibly not what you want. And I'm not even sure if this works.

• Don't use System.out in an Android app, use Log instead.

@dpr-odoo / @dso-odoo: This project needs some maintanence and the pull requests need some reviews. Please feel responsible for this project again. Thanks.
