Hi there,

I experienced problems with the generated IDs. I have a large list (data-bound) and got the message "Not unique in ID space of ..." although all explicitely given IDs were different. I managed to fix this error by explicitley giving the listitem a calculated ID (starting from listitem-0). I then changed the mold to paging. On my WINDOWS PC all was fine, but on a LINUX machine I got the same error message again (maybe not for the listitems but for something different?). The difference between the two systems let me think of a problem with threads or something like that.

The workaround was to implement my own IdGenerator that generates unique IDs in a threadsafe way. Now, all works fine.

Do you know if there's a problem with the standard way IDs are generated? Is the generation properly synchronized?

Kind regards,

Dominik
