Hello,
I have a problem with 3 nested
LiveCallbacks. For example, I have 3 selects (drop lists), and when the first
one is selected, the LiveCallback of the second stop working. My question is: am
I working correctly with LiveCallback or I am doing something wrong? What's the
errror?. I attach an example.
Thanks in advance and I look
forward for your help.
Best
wishes,
Juan M.
