multiple rows selected if adding some new rows [message #1708110]

Hi all,
I've a strange behaviour on my list table. If I add a new element (via a
button outside the table) and click into the list table all seems to be
ok. But if I add another element, both rows are highlighted (and also
all further added rows). It seems, that NatTable can't distinguish
between the newly created elements (although they have a different
position number which I gave them on creation time).
Any hints are welcome.

TIA,
Ralf.

Found it by myself... The mistake was that I used the id of the entities
for distinguishing (in IRowIdAccessor). But this id is always 0 if you
create a new entity. So, if you create multiple new entities they all
get the id 0. And thus NatTable can't distinguish between them. Solved
it by creating a unique position number.

Regards,
Ralf.
