Delete an one2many attribute entity in the master entity editor controller programmatically

Support
#1

Hi Everyone,

I have a master entity(which contains attributes with one2many relation) editor screen, with a custom button.
When the user presses the button i would like to delete some entries in the one2many attribute and add new entries.

I am using datacontainer for one2many attribute of the master entity.
In the web module i am using datamanager to remove the attribute entry from the database.
when i use datamanager.remove() of the one2many attribute entity it is deleting the master entity.
Could you please let me know how can i deleteone2many attribute entry from the database without deleting the master entity.

Thank in advance for the help
