Item5254: Javascript error when editing in pickaxe mode

Hit the pickaxe

Click somewhere in the tml and type for example a space.

Everytime I try I see a Javascript error reported in IE saying "Line 190, char1, object expected"

Taking into consideration the severe errors I have seen in practical use - this one should be at least analysed by someone that knows Javascript.

If a Javascript knowledgable can evaluate the error and it is harmless then downgrade to normal. If it is harmful (potential loss of work) then please fix before 4.2.0. You have hours, not days.

The error is caused by the call of handleKeyDown() in the text area field.

<textarea class="twikiTextarea twikiEditboxStyleProportional" id="topic" name="text" rows="22" cols="70" style='width:99%' onkeydown='handleKeyDown(event)'>

It looks like handleKeyDown() is not defined.

Frank is right. handlekeyDown is defined in twiki_edit.js, which is not included. The function simply filters the escape key in the edit box, because browsers have differing interpretations.

The error is irritating, but no more serious than that. If you are using IE with debugging enabled, it will halt the process, which is annoying, so it should be fixed. The fix is itself very low risk, as it's a copy-paste of existing code.

Fixed (you may need to restart your browser to force a JS reload)
