NRS script problem

System

Hi,

I have a strange problem using a nrs script with Filesite SP3 to check that
a field is set, and if not display a message when saving a file. It work so far as to check if the field is set and displays the message if not, but the ImanFileSaveDlg does not cancel by setting Dlg.CloseOnOK = False
Context.Add "iManExt.DoOK", False

The procedure continues with the PreOnOK and PostOnOK events and the
Save button is disabled. Canceling out of the Save File dialog then saves the
document.

Appreciate any suggestions.

filesave.nrs

CONST nrCustom3=27

Sub IManFileSaveDlg_OnOK(Dlg)
On Error Resume Next

'Msgbox Dlg.GetAttributeByID(nrCustom3)

If Dlg.GetAttributeByID(nrCustom3) = "" then
Msgbox "You have to fill in Custom3. Please click on Detail"
Dlg.CloseOnOK = False
Context.Add "iManExt.DoOK", False
End if
End Sub
