two quick questions:
- do you do the navigation/rendering setup on aspect 1, then it is
possible/likely it gets overwritten when the sync from aspect 0 comes in.
- do you clear the changelist of aspect 0 after you have synced all
changes to aspect 1? Otherwise everything would be recopied all the time
making the above case where you overwrite changes made on aspect 1 even
more likely.
Hope it helps,
Carsten
