Web Inspector: source frame should show the error to user when live edit is failed

[Pavel Podivilov]

Web Inspector: source frame should show the error to user when live edit is failed.

Currently, the only way to check whether live edit failed or succeeded is to open the console and check for warnings.
Source frame should indicate live edit failure more explicitly.

[Andrey Adaikin]

One way is just to open the console on an error, and leave the editor in the live edit mode, preserving the current (unsaved) changes.

Any other ideas?

I think you should either move this code to SourceFrame or move WebInspector.showConsole() here.

When live edit is succeeded, newBodyOrErrorMessage contains new source which may differ from current SourceFrame content.

Is there a valid scenario for this?

There is no such scenario according to Peter.
