Subject Re: Blank half-cell on page1; text showing on page 2
Date Fri, 11 Jan 2008 11:39:03 GMT
Akagi sent me sample files off-list and that allowed me to spot a bug in 
lists. Caution, this is technical (and for the record):

In the samples the tables were surrounded by list items. And the 900 
penalty assigned to ugly breaks isn’t handed over by the merging 
algorithm in the list code. In fact every break opportunity in 
descendents of list items will be transformed into a zero penalty. This 
is a bug that will need to be fixed, sooner or later.

That said, having all the content of a cell deferred to the next page 
results into such an ugly output that this mechanism will very probably 
be disabled in the next release, preventing such situations from 
happening despite the bug in lists.
