Re: [Exist-open] Autoincrement ID when saving a new doc?

[Marcus <StM...@gm...>]

Hi,
sorry for asking, but i don't understand the clue at the moment!?
How could that be used as a primary key (autoincremeted id) just like in 
traditional databases?

And cause you were asking, my abilities in java-programming are not soooo 
well and at the moment the time is missing, but perhaps in april i may have 
some time to try to help a bit, if none other had the chance to implement 
this feature till then. But i'm sure there are many othery more qualified 
than me :-)

Regards, Marcus
