I am attempting a secondary update to a dataset in its AfterPost
event. However the dataset then remains in dssEdit mode rather than
returning to dssBrowse once the AfterPost completes.

This seems to be because TIB_Dataset.SysPost does not action my
secondary Post due to 'IsPosting' (1) being True.

Further investigation suggests that 'IsPosting' returns true
when 'FIsPostingLevel' is greater than zero, which seems to the case
at the time the AfterPost event is called (2) - the decrement
of 'FPostingLevel' does not occur until later (3).

So is it posssible to re-update a dataset in its AfterPost event, and
if not are there any suggested workrounds please?

(W2K, IBO 4.2Ie, default transaction).

Thanks, Andy Garner.
