[TM4J-users] Merging Topicmaps using TMAPI

[<La...@gm...>]

Hello,=20

I would like to merge topicmaps by using TMAPI and write the result into =
a
XTM file. So I use the mergIn(TopicMap) method. But when I use the
serialize(OutPutStream, TopicMap) method from the tmapi-utils library I =
get
the following error:

java.lang.NullPointerException

By using a debugger I saw that when I=92m merging a Topicmap into =
another the
=93m_name=94 parameter from the Variant of a Topicname is not written. =
Is this a
bug or have I done something wrong? I=92m using TM4J 0.9.8 for TMAPI.
