# TikZ crosses-decoration does not work

When trying to compile the examples from the manual like

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.pathmorphing}
\begin{document}
\tikz \fill [decorate,decoration={crosses}] [fill=blue!20,draw=blue,thick] (0,0) -- (2,1) arc (90:-90:.5) -- cycle;
\end{document}

all I receive is

! Package pgfkeys Error: I do not know the key '/pgf/decoration/\pgfkeyscurrent
name ' and I am going to ignore it. Perhaps you misspelled it.

Is my tikz installation missing something or what do I do to make this work? The library is there (else I suppose the would be an error) and zigzag for instance is working.

• works here with \usetikzlibrary{decorations.shapes} and cycle; – Nico Vecchio Dec 12 '14 at 15:58
• @dcmst Yeah, the semicolon was missing above. But adding the shapes sublibrary does the trick. I wonder why is this not documented. You might want to make this an answer, so I can accept it. – oarfish Dec 12 '14 at 16:23
