[Semediawiki-user] Any thoughts on recursive queries with embedded output?

[Alex M. H. <ont...@on...>]

Sorry to bother the list again, but does anyone have any thoughts on  
missing information from recursive queries with embedded output (perhaps I  
am the only person with this issue....) I can't create an account on the  
SMW sandbox site (I get an "Could not create account: <Incorrect or  
missing confirmation code.>" error), so I can't verify that the issue  
exists elsewhere, but I would like to do so before filing a bug report.

To summarize, in a page structure with subpages, e.g., A/B/C/D/E/F/G,  
where each page contains a query for a subpage below it, and the result  
format is "embedded", queries appearing on pages on levels A/B, A/B/C, and  
A/B/C/D only return results down to A/B/C/D/E. Queries appearing on  
A/B/C/D/E do show A/B/C/D/E/F and A/B/C/D/E/F/G.

The queries are based upon explicitly declared properties appearing on the  
embedded subpages, and sorting is based on a custom sort key (rather than  
page names). I have set $smwgQMaxSize to 60 and $smwgQMaxDepth to 15 to  
see if those were factors (MaxSize below 40 was a factor for some pages),  
but even setting them to 10 or 20 (or 100) times those limits to test, the  
issue still arises.

Any help/advice/insight would be very helpful.

Thanks,
Alex
