Hi Readers, I have created the page which takes object of an entity ‘Sample’. I have to open page in microflow. So I have created a microflow which open that page and I have also created a create object activity (without commit object of sample) and passing to show page activity. I am able to open that page successfully. But sometimes I get the error popup on save microflow of that form. Error in console: Caused by: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreException: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.systemwideinterfaces.connectionbus.data.UniqueConstraintViolationRuntimeException: Duplicate column value violates its unique constraint: ERROR: duplicate key value violates unique constraint "pcvmodule$sample_pkey" Please let me know why I am getting this error and how to resolve
