error getting data from global method valuelist

Classic Servoy
1

Hello,

I have a valuelist with a global method, and it works fine except wehen I close the application it gives an error. Which is logical because at close it runs the method again.

error getting data from global method valuelist

java.lang.NullPointerException

Any suggestions how to avoid that?

Irene,

Do you have the stack trace from the java console or the log file?

this is an exception that happens when the solution is already closed (or closing). So it shouldn’t be a big problem of your actual solution
Servoy 6.0.1 will have a fix for this, so that this global method will not be executed at all anymore at that time
