Schema: mysql error - Multiple primary key defined

[itsa-sh]

It appears when creating a table the first integer field is considered a primary key and created; The example below will generate a mysql error:

[Illuminate\Database\QueryException]                                         
SQLSTATE[42000]: Syntax error or access violation: 1068 Multiple primary key defined (SQL: ***)

Schema::create('table_data', function(Blueprint $table)
{
    $table->engine = 'InnoDB';

    $table->integer('record_id', 10)->unsigned();
    $table->double('price', 8, 4);
    $table->date('date');

    $table->primary(['record_id', 'price', 'date']);
});

Where as the following does not throw an exception.

Schema::create('table_data', function(Blueprint $table)
{
    $table->engine = 'InnoDB';

    $table->string('record_id', 10);
    $table->double('price', 8, 4);
    $table->date('date');

    $table->primary(['record_id', 'price', 'date']);
});

EDIT: Also, it appears to create product_id as an AUTO_INCREMENT which is not true either.

What Laravel version please?

integer() second parameter was never meant for size length (check the documentation and code).
