My tray line numbers weren’t showing up in CFEclipse since upgrading to the Ganymede version of eclipse. My preferences were set correctly. I did a bit of googling but I didn’t actually find the solution until a few links down, so I thought I’d share the link love!
1. In directory
[workspace]/.metadata/.plugins/.org.eclipse.core.runtime/.settings/
2. Edit (or create) a text file called
.org.cfeclipse.cfml.pref
3. Add the following line:
lineNumberRuler=true
4. Restart Eclipse
