Popover not focused when closing in IE throws error.

[antkohan]

OpenUI5 version:

Browser/version (+device/version): Internet Explorer / 11.839.10586.0

Any other tested browsers/devices(OK/FAIL): Chrome (OK)

I have a sap.m.Popover that contains a list of rows, and each row has a cancel icon that, when pressed, removes it from the list. When the last row is removed, the popover is closed. However, in IE the popover appears not to regain focus before closing and a "get id of undefined" error is thrown. The error comes from a "document.activeElement.id" line in the popover's close function because document.activeElement may be null at that point.

Hello @antkohan ,
Could you please provide and jsbin example where the issue is reproducible?

Since there is no response from the author for more than 4 weeks I'm closing the ticket.

@Shtilianova document.activeElement can be null or document.body when no element is focused. Most browsers set it to document.body, but IE sets it to null. @antkohan is correct, a null check is needed unless you know that an element has the focus.

Edit: Here's the same issue in another lib... Note that I'm not an OpenUI5 user, I found this while doing research for similar report for a lib I'm contributing to.

angular/components#2760

@pygy and @antkohan , Here is an example with custom handling of deletion, working with the latest OpenUI5 version - https://jsbin.com/yowapeyaje/1/edit?html,output
Please elaborate further how the problem is reproducible.
Thank you
