Drag&Drop entry (WWW) to a group

JabRef 5.0-dev–snapshot–2019-02-19–master–623718aa9 Linux 4.9.0-8-amd64 amd64 Java 1.8.0_181

When I drag&drop an entry (type WWW) to group nothing happens. The entry does not appear in that group. But the entry itself updates it “groups” field with the name of the new group. Restart doesn’t help.

I can not reproduce this for all entries but for this.

Please look in the group _entry_date -> 2019-02 and try to drag the entry in it to the group Science -> Statistic. Also look into the groups field of the entry! MyJabRef_bug_report.bib.zip

Ok, if that is the case, the “Refine Supergroup” function appears to work as intended - initially I thought that irrespective of the interpretation it did not work since I assigned the item mentioned in the starting post to both the group “Statistic” and “Science” in the provided bib file. The item would then be shown in “Science” but not in “Statistic” - but that makes now sense, since “Statistic” is NOT the immediate subgroup of “Science” but that of “Methode”. If I assign the item also to “Methode” it will now also appear in “Statistic”. So apologies again for the confusion! Maybe the only take-home message here is that the help file needs to be a bit more clear about this. I have added a single sentence to explain the feature a little bit better, see here: https://github.com/JabRef/help.jabref.org/pull/202

I have to take it back, I can reproduce the behaviour and I think this is a bug:

As @Siedlerchr mentioned, the issue only appears when “Refine supergroup” is selected. I generally do not use this feature but use “Independent group”, which does not display the problem.

However, as far as I understand the “Refine supergroup” setting is meant to contain BOTH the subgroup entries AND the entries in the subgroup, i. e. following a Boolean “OR” statement (see http://help.jabref.org/en/Groups). But even, if a Boolean “AND” is intended, the issue still persists - the entry is not shown in the maintable, despite having selected the subgroup of interest.

I have tried this also with my own database and it appears to be a general problem with the “Refine supergroup” setting. So, apologies to @noMICROSOFTbuhtz for initially not being able to reproduce this behaviour and thanks to @Siedlerchr for spotting the problem.
