Can someone please tell me if the following is a Torque bug or a problem in my code?
I'm building a system that allows multilingual information for a restaurant.
The Restaurant object can have RestaurantInformation objects associated with it.
The RestaurantInformation object has a composite key made from a restaurant ID and a
2-character language field (there are 2 columns with primaryKey="true").
In my code, I fill out a new Restaurant object, then I fill out a new
RestaurantInformation object.
Finally, I add the RestaurantInformation object to the Restaurant object and call save
on the Restaurant.
At this point, I get an exception thrown from within BaseRestaurantInformation.
The generated code at the point of exception looks like this:
public void setPrimaryKey(ObjectKey key) throws TorqueException
{
SimpleKey[] keys = (SimpleKey[]) key.getValue(); // <-- Line 650
SimpleKey tmpKey = null;
setRestaurantNo(((NumberKey)keys[0]).intValue());
setLanguage(keys[1].toString());
}
