java.lang.ClassCastException: org.json.JSONObject$1 cannot be cast to java.lang.String binding the statement

Hi,

I’m receiving a JSON with the following format:

{"TICKET_ID":"1","ACCOUNT_ID":null,"TICKET_REF":null, ..a lot of stuff here.......}

but when I call jsonModel.save(). I’m getting the following exception:

02-23 16:51:06.085    7205-7536/com.glownet.app.staging.debug D/Retrofit﹕ java.lang.ClassCastException: org.json.JSONObject$1 cannot be cast to java.lang.String

        at com.raizlabs.android.dbflow.structure.container.BaseModelContainer.save(BaseModelContainer.java:126)

Because in the Model$Cointainer the following check is created:

 if (((java.lang.String)modelContainer.getValue("TICKET_REF")) != null)  {
  statement.bindString(1,((java.lang.String)modelContainer.getValue("TICKET_REF")));

A JSONObject.NULL is being tried to be converted to String with the cast.

How should I proceed?

The ticket ref is not a PK.

Its a bug. Good find. Best bet until I release 1.6.0 (probably tomorrow) is to subclass JSONModel and override this way:

@Override
    public Object getValue(String columnName) {
        Object value = getData() != null ? getData().opt(columnName) : null;
        if(JSONObject.NULL.equals(value)) {
            value = null;
        }
        return value;
    }

JSONObject wraps null values in a NULL object.

version 1.6.0 is now out
