SYMPTOMS
========
Executing the command TABLEUPDATE(.T.)on a view, with the SendUpdates property
set to False, returns True (.T.).
CAUSE
=====
The TableUpdate() command should return False if the update fails. In effect,
there must be an attempt to update at least one record that fails. When the view
property SendUpdates is set to False, TableUpdate never tries to update any
records, hence, the TableUpdate() returns True.
RESOLUTION
==========
Check the SendUpdates property of the view using the DBGetProp() function, and
apply the TableUpdate() function only in cases where the SendUpdates property is
set to True (.T.).
For example:
MyVar1=DBGETPROP("MyView","View","SendUpdates")
STATUS
======
This behavior is by design.
