'No data in this category. Try to "Include all popu...' when accessing a subtable after pagination in Page URLs or Page titles reports

[anonymous-matomo-user]

To reproduce :

• go to http://demo.piwik.org/index.php?module=CoreHome&action=index&idSite=1&period=month&date=2010-05-10
• click on Actions > Pages
• click on Next at the bottom of the page
• click on "+" on any entry of the "Page URL" column
• you get: 'No data in this category. Try to "Include all population".' instead of the correct subtree elements.

No easy fix in the code. All I know is that the ajax request has filter_offset=100 . After forcing filter_offset=0, the ajax request returns the correct values

Reference: http://dev.piwik.org/trac/changeset/2339 introduced pagination in Page titles and Page URLs.

I still have this issue in my Piwik installation (version 2.4.1).
The website adds the locale as first URL element, thus the first level elements of the page list contain a lot of sub-pages. As an example, page "de" is listed with 3409 pageviews for a given timeframe. If I expand clicking +, it just shows "No data in this category. Try to "Include all population"."
How can I "include all population"?

Btw. the behaviour seems not to be very consistent. Sometimes I get this message, sometimes I get the data (independent of the date range).

@bcg-didi maybe you get this errror when looking at "today's" statistics or do you also see it for other past days (like yesterday or some days last month)?

I can't really reproduce it.
E.g. right now I opened Piwik, the date range preselected was 2014-08-06 - 2014-08-12 (including today), expanding "de" showed the error message. Changing the date range "fixed" it, even if I then switched back to the same range.
May this be caused by an Ajax call timing out or something like that? I'll try to check the background requests with Firebug the next time it happens.

wild guess:
Maybe happens only if the option Allow Piwik archiving to trigger when reports are viewed from the browser is enabled and the report for the current day was not previously created.
