The code is not saved in ajax event!

A problem that presents itself to me for the first time and I can not understand why and how it comes out!
In an ajax event field_onchange (MOV_IDCAU_onChange) I write a few lines of code, save and it is not stored and the empty code frame reappears! :frowning:
I came out of the scriptcase, restarted the pc. Nothing!
I delete the event I rewrite it and do the same thing.
If I write the same code in otherField_OnChange (MOV_IDIVA_OnChange) or samefield_OnClick (MOV_IDCAU_OnClick) it works correctly!
What the hell is happening? how can I save the code?
Thank you all.

I answer myself!
I do not know what they are combining in NetMake and what ScriptCase combines.
Or rather I hope not to be sure otherwise …
However, I solved the problem by making a Vacuum to the scriptcase development database (nm_scriptcase.db)
Greetings and thanks to all.
