Oracle Forms Developer – Form Builder Reference, Volume 1

Usage Notes
string TRUE or FALSE.
ALLOW_MULTI-SELECT Returns the character
string TRUE or FALSE.
The values returned by datasource RECORD_GROUP and QUERY_TEXT do not necessarily reflect
the current data or state of the tree. The values returned are those that were set in Form Builder and not
those set using the SET_TREE_PROPERTY built-in.
