Dear Jason,

 

we are unsing IBO 5.3.3_1996.

The main connection have some entrys in there Defaultvalues list e.g.:

 

  Aktivierungsdat=NULL – this is a DATE field.

 

If i want now insert new data with the qry.insert function the error :

 

 EVariantTypeCastError Vatiant of type (NULL) could not convertet into TYP(Double)  

 

occurs and the insert fails.

 

With IBO 4.9 this works without any problems. What is here the failure?
