CodeMine RC2

I just generated RI code with the RI builder.

When it executes from my CodeMine app it intercept an operation that should'nt be allowed and I then have the following message "Unable to commit changes to... - Delete trigger failed"

But after that CodeMine gives me the error message

Error #1596 in Update line 44
"m.nThisRec = GETNEXTMODIFIED(m.nThisRec)"
Table buffering is not enabled.

Call Stack:
8 Cdedepartment.Cursordepartment.Cmdataaccess.Update (..\common50\cmdataa.vct)
7 Cdedepartment.Cursordepartment.Update (..\common50\cmdata.vct)

2 Formdepartment001.Beforeclose (..\custom\cforms.vct)
1 Formdepartment001.Queryunload (..\common50\cmforms.vct)

What I don't understand is why and how the buffering mode changed.

Any idea on how to solve this?
