Status: RESOLVED INVALID

(Skywriter Graveyard :: Command Line, defect)

Description

[Mark Spear]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.1 (KHTML, like Gecko) Chrome/6.0.437.3 Safari/534.1
Build Identifier: tip (changeset:   1980:f583805647a7)

Depending on what browser you use (and whether you have Firebug), the resulting error can vary a little bit:

Chrome, in the CLI history: "TypeError: Cannot read property 'typed' of undefined"
FF w/ Firebug, in the CLI history: "TypeError: history.requests[pointer] is undefined"

In the console: "Error executing command 'undefined'"
FF no Firebug, "console is not defined" is shown in the Error Console

Reproducible: Always

Steps to Reproduce:
1. Load up bespin
2. Give the CLI focus
3. Press up
Actual Results:  
Errors appear as described above

Expected Results:  
No errors. It could be debated whether it should env.commandLine.setInput('') or keep the currently typed input. I elected to keep the currently typed input, as that seems to be the behaviour of bash.

ACETRANSITION

The Skywriter project has merged with Ajax.org's Ace project (the full server part of which is their Cloud9 IDE project). Background on the change is here:

http://mozillalabs.com/skywriter/2011/01/18/mozilla-skywriter-has-been-merged-into-ace/

The bugs in the Skywriter product are not necessarily relevant for Ace and quite a bit of code has changed. For that reason, I'm closing all of these bugs. Problems that you have with Ace should be filed in the Ace issue tracker at GitHub:
