Subject Re: Possible bug in the columns tag with the convertDateTime tag
Date Mon, 04 Jun 2007 20:08:12 GMT

Thank you for your fast replying.

Maybe a dumb question but how can I make a stacktrace without the
write-privilege in the tomahawk? I thought can copy the source-code directly
in my project but something seems to be wrong.

Is there an easy way to do a stacktrace within tomahawk?
