Damascus v.1.1.4 fails to create two or more records

[icarrara]

From the sample, there are the Employee model and Position model.

The below steps are valid for every entities (Employee, Position, DeepPosition).

Deploy the portlet and create a first record in Employee entity and leave empty the "Title" and "Summary" Damascus's auto-generated fields.

Then try to create a second record in Employee entity and leave empty the "Title" and "Summary" Damascus's auto-generated fields. - you get the duplicate error message:
Duplicate entry '20124-0' for key 'IX_26F09727' because the 'urlTitle' field is everytime '0'.

The User needs to put something to avoid the error: Duplicate entry '20123-0' for key 'IX_A548BA27 - assuming there is one record already in place without content in "Title" and "Summary" Damascus's auto-generated fields.

The User needs to put something different from other records in those fields to avoid the error: Duplicate entry '20123-position-five' for key 'IX_A548BA27 - assuming there is one record already in place with "position-five" content in "Title" and "Summary" Damascus's auto-generated fields.

Using Damascus V.1.13 the issue is still here.
#89 doesn't solve the issue.

The issue affect every level of relationship between entities, for example Employee, Position, DeepPosition (an eventual third level of relatinship - the parent entity is Position).

In every entity, in "Edit" screen Damascus creates two fields:

Using damascus.build.number=V1.1.4TS20191213045547.

Steps to reproduce:

1. Insert a record without to fill the "Title" and "Summary" Damascus's auto-generated fields.

2. In databse you can see the below:
   

3. Insert a new record without to fill the "Title" and "Summary" Damascus's auto-generated fields.

4. You get the error: Duplicate entry '20123-0' for key 'IX_7C719B8F'

5. Edit and update the first record without to fill the "Title" and "Summary" Damascus's auto-generated fields.

6. In databse you can see the below:
   
   Damascus's logic copied the ID of the record in the "urlTitle" field so never Duplicate entry .... error happens.

The issue is confirmed when you insert a new record leaving empty the "Title" and "Summary" Damascus's auto-generated fields or putting in it values already presents in the table.
