Bug ID: 146113
Summary: Basic's IsNull documentation must mention that it also
returns True for object variables that don't refer to
an object (not initialized or set to Nothing) - at
least in non-VBA mode
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Documentation
Assignee: [email protected]

IsNull in LibreOffice Basic, unlike VBA, returns True when an object variable
is passed that doesn't refer to a valid object (e.g., just created not yet
assigned object, or assigned to Nothing literal). This is a conscious design
decision (see tdf#146112), and is widely used [1]. This should be mentioned in
the help. (And when bug 146112 is fixed, the VBA mode difference also needs to
be reflected in help.)
