> This issue is hard to explain with out a long example.
> crux of the problem is that the behavior of the if function, wrapped arround a boolean
field (ie: "{{if(fieldName,x,y)}}" ) is not consistent for documents that do not have any
value for that functio -- the behavior seems to  depend on whether or not other documents
in the same segment have a value for that field.
> for brevity, details will follow in a comment - but i've been able to reproduce on trunk,
4.3, and 4.3 (didn't look back farther then that)
> the work around is to explicitly use the {{exists()}} function in the if condition (ie:
"{{if(exists(fieldName),x,y)}}" )
> (Thanks to Elodie Sannier for reporting the initial symptoms of this on the mailing list)
