I'm trying to use a onUploadException event listener to catch failed uploads
and report the error as a validation error after the page reloads. I have
access to the error when the page reloads, but I don't know how to report the
error as it is not clear how to report an error to the validation tracker
outside of a validation event.
Here is what I have at the moment, the setup render fails because the
validation tracker isn't yet available.
@Environmental
private ValidationTracker tracker;
@SetupRender
public void setupRender() {
tracker.recordError(errorMessageService.getErrorMessageDescriptionText(exception)
}
@Persist(PersistenceConstants.FLASH)
@Property
private TotalUploadTooLargeException errMessage;
@OnEvent(UploadEvents.UPLOAD_EXCEPTION)
Object onUploadException(FileUploadException ex) throws
TotalUploadTooLargeException
{
errMessage = new TotalUploadTooLargeException(1, 1, ex);
return this;
}
