BibTeX, biblatex and biber ⇒ mciteplus | '\citenum' with Citation Sub-list

[galakhad]

Hi,

I faced a weird problem and couldn't find a solution over the internet. I am writing a paper using achemso style which uses mciteplus to make sub-lists of citations. It works fine if I use it as cite{headerref,*subref1,*subref2}, but in one place I need citations to be not as superscripts but in the main text, which may be achieved by \citenum{ref1,ref1}, and one of those citations must be complex (a sub-list). And although mciteplus manual sais "Mciteplus is fully compatible with ... \citenum...", when writing \citenum{heasref,*subref1,*subref2} I'm getting an error at compilation, saying "Warning--I didn't find a database entry for "*subref1"". Does anyone know any workaround for that problem?


Thank you very much in advance,
Sincerely,
Iakov
