APPEON: Datawindow Error "success"

Hi,

I get this error with appeon mobile:

I use a SQLite Datbase.

The datawindow has a dddw with a retrieval argument.

The error accurse when I retrieve the dddw in the constructor event.

An other dddw with retrieval argument in the same datawindow works.

The datawindow runs fine as PowerBuilder App but it fails with Appeon mobile.

Has anyone experienced this too?

Any suggestion?

TIA Ludwin
