Martin Kočí commented on MYFACES-3144:
--------------------------------------
I'm little lost here ... the patch (trinidad code) does not use String
comparisions. Is that patch applicable? Trinidad is well tested (and fast).
The performance problem is in repeated HashMap lookups. Yes, it's only minor
(compared with reflexion for example). But in large view it can save thousands
such lookups - minor improvement, but still improvement
