Stan,
I’m not sure why this response was missed, apologies. From the errors shown, I’m assuming you’ve installed CodeMix into MyEclipse, and these validators will not respond to the typical MyEclipse validation exclusion settings – not yet, at least.
Could you see if disabling the CSS validator at Window > Preferences > CodeMix > Languages > Project Validation makes a difference? I will say that there are some known enablement/control issues here that we are working on fixing right now, so not entirely sure that setting will help. Do let us know.
