Java swing three relative comboboxes

Question

I have three relative comboboxes lists that take data from the database, and if I change one, the other also changes through SetModel () method. The problem is that whenever a new pattern, the data in the other lists are changed, the listener again reacts to them. How can I solve this problem? Thanks in advance.

Answer 1

the listener again reacts to them

1. remove the listener
2. do your processing
3. add the listener back to the component
