Hello,

I have this in my library class on the instance side :

 
updateRoot: anHtmlRoot
    super updateRoot: anHtmlRoot.
    anHtmlRoot stylesheet url: self class / #mainCss.
    anHtmlRoot javascript url: self class / #mainJs

and a file mainCss on the instance side filled with css

and still the css is not found

anyone idea why ?

if needed I can put my whole code on github.

Regards,

Roelof
