Exporting Cassandra data causes NullPointer Exception

[deejbee]

Hi, not sure if this is a known issue (I searched here) or I'm doing something wrong. I have a small Cassandra table (just 200 rows) in a keyspace but I wanted to copy it to another keyspace on the same host. The destination table already exists, is empty and I re-mapped a column.

When I click finish on the Export it throws a "Data export error" window with "java.lang.NullPointerException: NullPointerException" with no more detail.

Export resultset and Export functions seem to cause the same exception. It seems to do it for all transfer target types (XML, JSON etc)

Error log shows this:
Message: org.jkiss.dbeaver.model.exe.DBCException Plug-in: org.jkiss.dbeaver.model
Message: Unhandled event loop exception Plug-in: org.eclipse.ui

So it suggests its nothing wrong with the export itself.

Any ideas?

Thx.
