try writing the fieldname all in lower case: "leadsource" and let us know.
When you created works, but when you editing not ...
The same code is executed in all cases, so I doubt that is the problem. I tried it anyway and the field appeared correctly transformed in all three validations.
Try online demo, user testdmy, field industry ( atividade )
You must use the correct module and field names:
Leads > not leads
All module names start with a first letter in uppercase ?
No, each module has its own capitalization. I recommend you access the module and look at the value of the "module" parameter or look in the tabdata.php or modules/ directory for the exact name to use.
What name I use, when wish created a BP in Tasks modules?
I testing cbCalendar and Calendar, but not working
