I have utilized your deep clone functionality to fit our organizations needs.

Basically we have the following scenario :

We have a Quote Request, which has Vehicle Models related to it and you have accesories related to the models.

Below is the code we are using. The issue we are facing is if a quote has more than one Model it fails with the error :
Record ID: cannot specify Id in an insert call

The Code works if there is 1 model with 1 or more accessories attached to it. The issue comes in when there is 2 or more vehicle models attached to a quote.

Is there any solution to the above issue we are facing?

//added an instance varaible for the standard controller
private ApexPages.StandardController controller {get; set;}

// add the instance for the variables being passed by id on the url

// set the id of the record that is created — ONLY USED BY THE TEST CLASS

// initialize the controller

Thank you for your efforts and the education. I love reading and learning from these posts. I’m needing to clone opportunities and a custom related object (not master-detail but rather a lookup relationship). It seems that this method would work well for that. Anything I’m missing?

Can we extend this code to do the deeper clone like

Account –> opportunity –> opportunitylineitems

I have one more question, can we do deeper clone up to three levels?

If so do we hit the governor limits for SOQL Queries?

Specifically, I have a template of related records related to a parent (Object 1). I want to relate that parent record (Object 1 and Object 2) and copy the related records into another related list of records that is a child of Object 2.

thank you for any input you can provide
