Stack trace icon is sometimes not displayed
-------------------------------------------

                 Key: CONSPLUG-19
                 URL: http://jira.qos.ch/browse/CONSPLUG-19
             Project: Console Plugin
          Issue Type: Bug
          Components: interface
         Environment: Red Hat Enterprise Linux 5, Eclipse 3.5
            Reporter: Richard Fearn
            Assignee: Logback dev list
            Priority: Minor


The stack trace icon at the left hand side of the Logback View isn't always displayed. If a logging event with a stack trace is displayed in the view first, the icon is displayed in the first row and the view seems to work normally.

But if an event without a stack trace is displayed first, without an icon, the icon doesn't seem to be displayed for all subsequent rows.

I think this might due to using a virtual table with a label provider that provides {{null}} column images. I've changed {{getColumnImage}} to return a blank image instead of {{null}} if the event doesn't have a stack trace, and that seems to fix the problem.
