When i saw it, i reported this as a bug at NetBeans issuezilla . Well the reply really struck me dumb :
"This is supposed to be a cool feature - the IDE is showing you that these variables are unused. This isOh yes, NetBeans was the best choice for writing Java code, now it's turning to be the best programming IDE available in general!
similar to the Java support where unused import and variables are also shown in gray."
- Java (including all the goodies from J2EE)
- Ruby / Ruby On Rails
- plus more i don't know, or supported by plugins
Check out yourself all the v5.5 features or the upcoming v6 features . Thank you community!!!
