Problem with IWDBGrid Async refresh

[Comograma]

You don't have debug information in your application which causes your call stack to be useless.

Review this document and change your project accordingly, so you will have a usable call stack:

Ok, I'll try that and see if I can see what's happening.
With v15.2.9 another error, a different error happens:
  404 - Not found
  Resource not found in Comograma_Comogest_FAC_BO2Web_Application

  If this condition persists, please report it to the administrator.

Downgraded to v12.5.7 and all good!! Don't get upset with me Alexandre, but it is strange that the exact same code do not function with v15.2.8 and v15.2.9 and works with v15.2.7. Nothing changed.
I attatched the a new pdf with the stack trace.
