Bug 110955 – Web Inspector: timeline stops working on certain sites

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

[Yury Semikhatsky]

User report:

"I've noticed that timeline stops working on certain sites.

F.ex. go to www.tv2.dk, start timeline recording.

Now, only a few events are shown in the list, and after stopping recording, the slider at the top is not working (list of events is not updated when sliding in the timeline).

Also, it is not possible to start recording again. Only if I close developer tools and open them again.

I actually noticed this a while ago in Canary, but I assumed it would be fixed before hitting release.

Anyone else having this problem?"

There is an exception in the console if you open inspector on inspector:

Uncaught Error: NotFoundError: DOM Exception 8 View.js:478
Element.removeChild View.js:478
WebInspector.TimelinePanel._refreshRecords TimelinePanel.js:868
WebInspector.TimelinePanel._refresh TimelinePanel.js:771

Seems like a drawback of untyped payloads...

We're thinking about making them typed =)
