Hi Akshay, I've got the same issue @neoblack has:
The issue presents when inside the $crud you set either callback_before_insert or callback_before_update like$crud ->callback_before_insert(array($this,'my_callback') ) ->callback_before_update(array($this,'other_callback') ) ;
When added to crud, the uploads are correct, however, when saving data and returning to list view, the value for filelds set as upload type will have a null value, in other words, files url are not being saved as field values
You would get "No files" as value in view list
If I comment these callbacks everything works fine.
How to solve the callback issue?
Hi Sorry for late reply, I was out of station, this issue has been fixed in current release, it was due to callback override
Go through github, let me know if you find any difficulties
