Using multiselect with timeline in web interface filter. Bug?

[pirate]

Hello.
I made a filter in Zabbix web-interface to select multiple users and add widgets period.
The problem is displayed in the video https://www.youtube.com/watch?v=Al5-jViNnSA
Has anyone encountered a similar problem and could you solve it?

I haven't added new pages to the 3.x web interface yet, so I can't comment much. I'd reckon that you're not escaping or creating the list correctly that gets sent.

How I would tackle the problem is to activate the Developer Tools (F12 in Chrome) in the web browser and then go to its Network tab so that you can see the new requests sent to the Zabbix web server from that tab.
So after enabling the Developer Tools and navigating to the Network tab, repeat the steps from your video and compare the Query String Parameters section (which is also part of the HTTP GET's URL).

Unfortunately without having your source code with the modifications I cannot say much more than this.
