1162708 - Scratchpad doesn't work when paused in the debugger

Status: RESOLVED DUPLICATE of bug 966262

(DevTools :: Debugger, defect)

Description

[Jeff Griffiths (:canuckistani) (:⚡︎)]

STR:

1. go to http://devtools-dash.paas.canuckistani.ca/tools-relative.html
2. open the debugger, set a breakpoint at line 98 in app.js ( the code may change, this is the line 'var graph = {' )
3. reload the page.
4. once the debugger is paused at the breakpoint, open scratchpad
5. run this code: 

window.__foo = data;

Expected: I should see my data printed to the console

Actual: I get some huge tracebacks, see below

Workaround: assign data to a global in the console and use it in scratchpad without pausing in the debugger.

Comment 1

[Jeff Griffiths (:canuckistani) (:⚡︎)]

My expectation ( possibly wrong ) was when I'm paused at a breakpoint in the debugger that I have access to local variables in the current scope. I do in the console, but do not from scratchpad.

Comment 2

[Panos Astithas (he/him) [:past] (please ni?)]

Yup, we should do this.
