Can't use parentid in a filter creation. Only accept numbers.

Hi, I found one error when you create one List. If you have one custom module or legacy module like Calendar. And try to create a new List for filter values in a Listview model, try to use a field with name parentid or parent_id. Only the accepted values are numbers, if you write any letters shows one error "View already exists".

Follow these steps:

Go to Calendar -> List view -> Add a new list -> Pick "Related To" -> "Contains" -> ABC (View already exists).

Then change ABC with 123. List saved correct.

If you go to the database, open the table vtiger_cvadvfilter and in the value field write your string. Then the list work's correct.

I know the module calendar is special. But if you have a custom module or a paid extension with this name field, you can't filter any registry.
