Hello,
I'm trying to update an integer UDF value using a simple business rule.
My goal is to increase the value of this field by one every time the event is triggered.
This is the Action:

My field was originally udf.Bolla = 100
Variable myBolla is initialized with udf.Bolla
After the rule is run, the value is: udf.Bolla = 100+1
It looks like the value is always managed as a string, even if the UDF field is declared Integer.
How can I fix this issue?
Thank you in advance for any useful hint.
