Bug 126855 – Web Inspector: scope chain details sidebar doesn't update values modified via console

• Component: Web Inspector
• Status: RESOLVED FIXED

[Blaze Burg]

Test case:

when paused, add a new property to some object visible in the scope chain details sidebar. The new property won't be added to the tree until you take a step in the debugger.

Thanks for looking into this!

This would be better as an event that the sidebar observes. Having this low-level view class directly call a higher-level class is a layering violation.

RuntimeManager would be a good place to fire the event that the sidebar observes.

[Timothy Hatcher]

Having RuntimeManager fire it after doing an evaluate would catch any other place we evaluate expressions.

Thanks for the feedback, uploaded new patch.

Two things I wasn’t sure about:
1) I didn’t add any data to the event, since it seems like most events don’t include data unless something will use it. Happy to add if you want though.
2) I didn’t refactor RuntimeManager#evaluateInInspectedWindow() to not have a callback at all, since having a callback made more sense for the things which were calling that method (since they needed to have callbacks specific to the invocation, as opposed to generic like the event is used.) Plus, one of the other args changes what args get passed to the callback.

You need to bind.(this) on both evalCallback calls. There is one on RuntimeManager.js a few lines down (line 75 after your patches). Otherwise, just typing in the console normally (not paused) will throw an exception right?
