940314 - DOMException in inspectorActor.querySelector

Status: RESOLVED DUPLICATE of bug 962647

(DevTools Graveyard :: WebIDE, defect)

Description

[Paul Rouget [:paul]]

Once connected to the message app, searching for "#messages-input" remove the red halo (so the node is found), but the node is not selected in the markup view.

adb logcat tells me:

I/Gecko   ( 6048): console.error:

(it stops here, logcat trunks the output)

I don't get the error message anymore, but there's a very weird bug here:

First, searching for "#messages-input" doesn't appear to fail, but nothing is selected in the markup view

Picking a node doesn't appear to work correctly: node is highlighted (red rectangle), but nothing is selected in the markupview.

Also, browsing the markup view down to #message-edit-form exposes some weird behavior. I don't think the right elements are highlighted. The markup view looks out of sync. In this screenshot for example: http://i.imgur.com/3k9II1X.png , clicking on the empty line will highlight the message input form.

The DOMException you're seeing is cause by the selector-search but isn't the root cause of the nodes not appearing in the markup-view. 
What's happening here is that when you first type `#`, that character gets sent, but doing a doc.qsa('#') throws a DOMException invalid string. It's not a big deal though because right after that, new characters are being typed and eventually, a valid selector is sent, nodes are found, and sent back to the client.

The reason why the markup-view then doesn't update correctly is because the nodes returned aren't attached to the walker's tree. I have a fix for bug 962647 that should resolve this.
I'll dup the bug when I'm sure.

Closing this as dup of 962647.
