setting core data object a second time causes EXC_BAD_ACCESS

I have a customer object with two relationships, a document and an asset.

When I create an Asset I have a condition where I check for the existence of a document object in the customer. If it does not exist, I create one and set the document's customer relationship.

Right after that, I create the asset. However, I am getting a crash when trying to set the customer to the asset with an EXC_BAD_ACCESS.

Whats strange is this code use to work, but I have no idea what would of changed to suddenly cause a crash here.

this is the code:

if (![customer inspectionDocument])  //check if a document exists
{
    // if it doesn't create one
    Document *document = [Document newDocument];
    document.customer = customer;
    //sets additional properties
}

// now create the asset
Asset *asset = [Asset newObject];
asset.customer = customer;   // <---- crash occurs here
//sets additional properties

I assume that you're using a relationship to store the customer reference to your document and asset. Normally, you should have a reverse relationship. Have you tried setting the document property on the customer object instead of the opposite?

if (![customer inspectionDocument]) {

    // if it doesn't create one
    customer.document = [Document newDocument];
}

customer.asset = [Asset newObject];
