Status: VERIFIED FIXED

(DevTools :: Debugger, defect, P1)

Description

[Jan Honza Odvarko [:Honza] (always need-info? me)]

STRs:

1. Load this page: http://janodvarko.cz/tests/debugger/watchpoints/
2. Follow the test case #1
3. When JS execution is paused in step #6 remove the Watchpoint
4. Immediately create new one (the same)
5. See the Browser Console, there is an exception: uncaught exception: Protocol error (noSuchActor): No such actor for ID: server0.conn5.child1/obj36

@Jason, can you please look at this?

Note that another scenario that is also causing this bug:

1. Create a Watchpoint in an object (you can use the person from STRs comment #0)
2. Hover mouse over the person object in the source code
3. Click on the WP marker in the tooltip

You can also click in a tooltip within the Watch Expressions panel.
All rendered using the same component I guess.

Decision: Only show markers only in the Scopes panel, not anywhere else. Follow-up bug to add this as feature.
