Hi friends,
I have generated backend by symfony.
Suppose i have a table in schema.yml
listing:
id:
type: char
name:
Then i have generated Model, Sql and Backend by symfony.
Now the problem is: If, in the database "listing.type" have null
value and i open a listing by symfony backend to Edit.
We did not done any changes and save this listing. Then all columns
that have null values replaced by blank values for this listing.
