This seems to be a bug or a limitation in the TreeMapper, most likely
because a specific behaviour of your content provider or tree. It's not
obvious to figure out what's wrong with this description.
Can you please open a bug on bugs.eclipse.org and attach to the report a
very minimal piece of code that allows to reproduce the issue? Even
better, do you think you could write a simple JUnit test case to
highlight this issue?

Cheers,

Thanks. I'll try to find some time to look at it soon.
In the meantime, you can maybe try to debug that by yourself. You can
view source at
http://git.eclipse.org/c/nebula/org.eclipse.nebula.git/tree/widgets/treemapper
.. The Gerrit repo URL is can be found at
https://git.eclipse.org/r/#/admin/projects/nebula/org.eclipse.nebula
