As explained in http://jetbrains.dzone.com/articles/top-20-code-completions-in-intellij-idea
Code completion should also suggest applicable attributes from within the current scope of variables as parameters for methods.
Fixed in jet-main.
Integrated into 'main-golden', will be available in build *201304272301* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
