Buggy tags implementation

[serg1990io]

Hi!
After an entire day trying to fix the issue, I give up leaving the thing to experts.
The relation between Jdownloads and joomla tags is almost unusable, let me explain (I'm sorry for my terrible english):

• I'm using Joomla 3.5.0
• I'm using Jdownloads 3.2.44
• In Jdownloads I have multiple categories, but I have a second level of organization based on tags

In frontend users can choose to display files in single Jdownloads category and it works brillantly. The issue begins when I use a list of tagged elements. I correcty see the list of my tagged downloads, but dates are wrong. I've investigated a lot and the issue is this: when you create or modify publication date using Jdownloads the value is updated in the #####_jdownloads_files table in database, while tags date is taken from #####_ucm_content table (core_created_time).

A second effect of this issue is that if you remove an element from Jdownloads it will still appear in the tag.

I know that my explanation is terrible, but if you need further informations I'll try to help as much as I can.

Thank you very much!

Hi
I have looked at the first case and there does seem to be a problem
The table below shows information taken from the 3 Downloads from jD backend and for an Article
Title                                             Created      Modified   Published     Type
Audit Letter-As Sent                        2015-07-12   Never      2015-11-04  Download
decorative-products  For Uploaders  2015-07-12   2016-04-11 2015-08-31  Download
service sheet                                 2015-07-12   2016-05-10 2015-08-31  Download
Test Article- Content Plugin             2015-10-08   2016-05-09 2015-10-08  Article

If these are compared to the attached images (shown with Compact Tag Display) then there are obvious discrepancies
For Reference the Tag Creation Date was 2015-08-18 and Tag Modified Date was 2016-05-02

After the first checks i have this results:
1) the Modified date is always updated in ucm_content when you change a Download with a tag in jDownloads (see first pic).
2) when i delete an article in Joomla (empty trash) it still exists the early used tag for him in the _tags table (not used in any other content)
3) the same in ucm_content

So i am not sure where shall be here a bug. As we have (nearly) the same behaviors in jDownloads as in Joomla.

Or i need maybe more details?

Think I have found the situation.
First if I checked the dates shown in ---ucm-content and as shown on tags display were consistent.  They were, see pics.

I then opened a Download in backend and saved it.  Both ucm_content and tag display showed today's date.  So good.

Went to Download again in backend and changed  modified date to a few days earlier by using the calendar function. Saved and closed. Verified that download modified date saved in jdownloads_files was the correctly changed one.
But the ucm_content table entry had not been change to the selected modified date.  It still had today's date.  So problem seems to be when uses the Calendar function to set a modified date.  Probably applies to  created date as well but I did not try.
