Dear all, this is my first 'official' Bug Report, so bear with me, I try to give all the needed informations to make this error descriptive. Summary: I do have a set of articles in my Mediawiki, all categorized and with a set number of semantic attributes, by which the #ask selection will work on. If the #ask display results using 'format=table', I will get the correct number of articles as result. Using the very same #ask, but changing format to 'calendar', 'timeline' or 'eventline', I will only see a small subset of articles displayed. The 'limit=' parameter was set to 9999, to exculde an 'cut off' selection from this error. This leads me to believe the error I am experiencing may be buried within the Semantic Results Format module. Environmental Setup: I created a form to let users create articles in a specified form from their attribute selection like this: {{{info|page name=<PatchTemplate[customer]> (<PatchTemplate[environment]>) - <PatchTemplate[action]> - <PatchTemplate[ticket]>}}} {{{for template|PatchTemplate}}} {| class="formtable" ! Customer: | {{{field|Customer Name|input type=dropdown|values from property=customer|mandatory}}} |- ! to be done by: | {{{field|done_by|mandatory|input type=datepicker |disable input field |show reset button |show week numbers |week start=1 |highlight days of week=0 |date format=dd.mm.yy}}} |- ....... |} The template 'PatchTemplate' defines all my field with their attributes, which is pretty straightforward and does not contain anything special: {| class="wikitable" ! Customer | [[customer::{{{customer|}}}]] |- ! to be done by | [[done_by::{{{done_by|}}}]] |- ...... |} This way, I have articles created, all put into the same category (using the template) and with valid attributes, especially the date attribute done_by, which gets relevant for the selection. The selection looks like this: {{#ask: [[Category:Dates]] [[done_by::>{{#calendarstartdate:}}]] [[done_by::<{{#calendarenddate:}}]] |? done_by |? customer |sort=done_by |format=table }} This selection shows me all articles with attribute 'done_by' within the calendar start and end date (in this page I also have the calendar defined, this sets the dates accordingly). Using the same #ask, but with format set to calendar, timeline or eventline, not all selected articles are shown. On a little sidenote, I also recognised that the colorizing of different calendar-dates (in this case, based on priorities) does not work either. Maybe this is linked together ?

Thanks for the report :) If you get all the stuff with table, but not with timeline, 2 reasons stand out as likely: * The formats have an additional limit (I am not aware of any such limit, and a quick look through the code did not uncover one) * Your results are not all of type date. Only those of type date will be displayed in the mentioned formats. Table will display everything.
Hi Jeroen, I did look through the PHP code myself (I know my way around a bit through code) and I did some test runs myself. I have to admit that at some point, with all the inherited objects, I had to pass out. Also, I was wrong in saying that I get the errors on #ask, they are on #compound_query. Sorry about that. Regarding your comment with the results not all being of type date. I did another testpage and it seems I'm getting a bit closer to what is happening. This page contains just two queries: {{#ask: [[Category:dates]] [[done_by::>{{#calendarstartdate:}}]] [[done_by::<{{#calendarenddate:}}]] |? done_by |sort=done_by |format=calendar }} {{#compound_query: [[Category:dates]][[Has State::done]];? done_by;color=#dd0000; |[[Category:dates]][[Has State::open]];? done_by;color=#00dd00; |[[Category:dates]];? done_by;color=#0000dd; | format=calendar | limit=999 }} The first query seems to work for me now, as it displays the articles with the entered date (confirmed with counting articles using format=table). Comparing this with the compound_query one, I only get parts of the #ask results. In numbers, I have 22 results for #ask, but only 7 for #compound_query. This said, all the articles get created using an included form, to make sure only allowed values are entered. This way I try to exclude formatting errors. Additional information, 'Attribute:Has state' article contains: -------- Type [[Datatype::String]]. * [[Allows value::open]] * [[Allows value::done]] * [[Allows value::in progress]] -------- Plus the color-attribute is not being set, but this may not be directly involved with this error. Is there anything else i can test or supply to get this one nailed down ? Thanks in advance. Thorsten Nickel
Hi Thorsten, I have a guess as to what might be causing this. A few months ago, I made a fix to Semantic Compound Queries, but for some reason I never bothered to release new version, so the version in Semantic Bundle (which you're using) still has the old code. If possible, could you replace your file SCQ_QueryProcessor.php with this? http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/SemanticCompoundQueries/SCQ_QueryProcessor.php If you can, please let me know if that fixes the bug - if so, I'll release a new version of SCQ right away.
Hi Yaron, I replaced the code with the Trunk SVN one, but this does not change anything in the result. I made a diff with the two code-modules and am sure to have put up the SVN one. But, this update does not brake anything, so thats good. If I could make just a guess, it seems to me that when running through the list of articles matching the query, with the compound query there is an early break condition, leading to not selecting all available articles. And this condition does not apply with a 'normal' #ask query. Is there a way I can turn on some debugging or the like perhaps ? Regarding the 'color' attribute in the compound query it may help, when I examine the generated HTML from the calendar, it seems to me that the additional attribute color is not submitted at all: ---- HTML CODE ---- <table class="month_calendar"> <tbody> <tr class="weekdays"> <tr> <td> <div class="day day_other_month">27</div> <div class="main"> <p> <a title="_Customer_ - _Object_ - _Reference_" href="/w/xxxxx">_Customer_ - _Object_ - _Reference_</a> </p> </div> </td> <td> ..... </td> </tr> .... ---- END HTML ---- Thanks in advance, Thorsten
Hi Thorsten, Please try changing your #compound_query call to this: {{#compound_query: [[Category:dates]][[Has State::done]];? done_by;color=#dd0000;limit=999 |[[Category:dates]][[Has State::open]];? done_by;color=#00dd00;limit=999 |[[Category:dates]];? done_by;color=#0000dd;limit=999 | format=calendar }} ...and see if that helps. The limit has to be set individually for each sub-query; that has caused problems for people before.
Hi Yaron, I can confirm that in setting the limits individually per sub-query, I get all the results I like to have. Now if the coloring on the calendar would work, I'd be more than grateful, especially since this would be a killer-feature for the management-level collegues ;-) Thank you so much, Thorsten BTW, is this documented somewhere ?
Okay, that's progress. (No, the fact that "limit" needs to be per-subquery isn't documented, though it should be.) Although note that you should be able to use the #calendarstartdate, #calendarenddate thing in #compound_query too, so the huge limit might not be necessary. For "color" - I really don't know. If that's the exact query you have, it should work; my only guess is that the version you have of one or more extensions contains some bug that has since been fixed. We're actually planning to release a new version of Semantic Bundle later today; so I would recommend installing that one once it's out, and seeing if that fixes the problem.
Hi Yaron, I'm very happy to confirm that with the new Bundle all my errors are abandoned, i.e. the coloring does work again for me. With using the limit per subquery I get all results I want, So, this bug is resolved for me :-). So long, Thorsten
Okay, great. For record-keeping, I'm changing the status of this bug to "invalid", since I assume the color issue was already fixed by the time you discovered it; no offense intended.
