Editor error [message #469673] Tue, 12 May 2009 19:15 Go to next message

I'm using the COBOL 3.4 plugin with OpenSUSE 11.1 and the provided Eclipse
(Ganymede, 3.4). It appears to integrate OK. When I try to edit a new
COBOL program or open an existing COBOL program (from the filesystem), I
get the following error:

Could not open the editor: The editor class could not be instantiated.
This usually indicates a missing no-arg constructor or that the editor's
class name was mistyped in plugin.xml.

When I click on Details>> I get the following:

I've search many places for an error like this and have yet to find a

Eclipse 3.4.1 appears to work much better with the COBOL Plugin. Thanks.

An additional problem, now. I'm trying to edit an existing program by
importing it into a project. When I open it in the editor, it appears to
overrun the left margin of the editor by 5 characters. In other words,
the text starts 5 characters to the left of the editing position.

I have the COBOL tab stop set to 8. This file was originally edited with
vi. The lines in the file (at least the first few that I've looked at)
have x'09' as the first character.

I can send a screen shot via email if it's easier to visualize.

Rich.
