Hello everyone, I need an urgent help, I'm doing a JavaFX course, and in it we have to do a calculator using Scene Builder, I was able to do everything that was requested, but when I put it to onAction, when generating the execution method Button, in XML it appears with a "#", example: onAction = "# onClickNumeros", and I believe that for this reason Netbeans is not compiling the code, nor even finding the method in the control file.
On the lines that have the "#" appears the following message: "The controller is not defined in the root component", I'm already searching for three days to solve this, I need a lot of help with this to be able to evolve in the course
Thanks so much if anyone can help me !!
This is the code:
