RelationManager problem with duplicate relationship

I have a N-M relation with RelationManager:

companies

companies

companies

companies and

items

items

items

items and pivot table

company_item

company_item

company_item

company_item. Pivot table has a boolean

obsolete

obsolete

obsolete

obsolete field.

The problem is that I have a ToggleColumn on this obsolete field but when a company has two same items (same

item_id

item_id

item_id

item_id but different

pivot_id

pivot_id

pivot_id

pivot_id, the toggle will work on first ocurrence because is taking

item_id

item_id

item_id

item_id and should take

pivot_id

pivot_id

pivot_id

pivot_id for this.

Instead of taking

pivot_id

pivot_id

pivot_id

pivot_id (2809 and 5895) is taking the

item_id

item_id

item_id

item_id.

Solution

Ok, I solved with

allowDuplicates()

allowDuplicates()

allowDuplicates()

allowDuplicates():

return $table
        ->allowDuplicates();

return $table
        ->allowDuplicates();

return $table
        ->allowDuplicates();

return $table
        ->allowDuplicates();
