This used to work and I'm fairly sure I haven't changed any of the
TIB_Query properties.

Using the default TIB_Query properties, I call:

qry->Insert();

IBO throws an exception warning me that:

"myfieldname is a required field"

Tracing into Insert() it goes into SysInsert, SysPost and finally
CheckRequiredFields where the exception is thrown.

I know I can set CheckRequired=false, but I want this to check the
params when I've finished editing the row.

None of my other queries throw on non-null fields when I insert a row.

Any ideas?

TIA
