hi everybody!
i have some problem with bibliography editing in my libreoffice document.
if i open document i have bibliography database connected to it and placed
in standard place in .config/ directory.
if i trying to open menu View->Data Source i can see and edit data in
bibliography.
Also i have my bibliography in registered databases.
But when i trying edit data in bibliography through menu
Tools->Bibliography database - i retrieve empty sheet for table of
database.
And also when i trying to add reference from bibliograhy through menu
Insert->Indexes and tables->Bibliography Entry i can not add entries from
the database. Corresponding "short name" combobox is not filled with
items. It is empty.
How i can connect my bibliograhy to my document?
Thanks in advance!
