Invalid conversion from runtime type String to SOBJECT:Opportunity

I've created a VF page to add multiple products based of http://bobbuzzard.blogspot.co.uk/2011/07/managing-list-of-new-records-in.html

 

Everything works execpt when I try to Save I get the error: common.apex.runtime.impl.ExecutionException: Invalid conversion from runtime type String to SOBJECT:Opportunity

 
But, I'm not assign the opportunity to anything and System.debug don't get trigger in the Save function. Any help will greatly appriciated! Thanks

Hi

 

are you using above code to create multiple products at a time? then what is use of the below lines of code

 

String oppId = (String)Apexpages.currentPage().getParameters().get('oppid');
        this.oppSO = [Select Id, Name From Opportunity Where Id = :oppId];
        System.debug('@@@this.oppSO: ' + this.oppSO);

Thanks for replying. I fixed the issue by removing.
