Hi all, 

Sorry in advance for such a newbie question, but I am currently having problems when using the set methods when comparing custom classes, and I can't seem to find the error. I have the following class:

public class ProductModelerController{
	public String name {get{return name;} set {name = value;}}
    public String role {get{return role;} set {role = value;}}

    private Set<ProductModelController> assignedModels;
    private integer identifier;


    
    public void updateProductModels(Set<ProductModelController> updatedModels){
        //Compare each of the product models and verify it has the most updated information
        
        if(!this.assignedModels.isEmpty()){
            for(ProductModelController model: updatedModels){
                //Search for the model in the list of assignedModels
                    for(ProductModelController storedModel: this.assignedModels){
                        //If the model name is the same, update its contents
                        if (model.name == storedModel.name){
                            
                            storedModel.updateProductModel(model);
                        }
                }
            }
            if (!this.assignedModels.containsAll(updatedModels)){
             //Updates the set of available models with the recently added models
                
                Set<ProductModelController> newModels = updatedModels.clone();
                newModels.removeAll(this.assignedModels);
                this.assignedModels.addAll(newModels);
            }
            
        }
        else{
        	this.assignedModels = updatedModels;
        }
    }
}

When testing it, I am getting an error in the moment the code reach  

if (!this.assignedModels.containsAll(updatedModels)){

The error is: System.UnexpectedException: User defined type found in unsupported code path.

I haven't seen something like that before, and perhaps any of you have a clue what's wrong here? any help would be greatly appreciated!

Thanks and again sorry for the newbie question
