Join symbols do not work in LaTeX caption

[szarnyasg]

The latest tikz-based join symbols result in an error when used for table captions.

It seems that the trouble is that LaTeX indexes figure captions. The solution is to add an additional custom caption as \caption[...]{...}.

A placeholder also works:

\caption[]{Social network example represented graphically, formally, and as nested relations. $\join$}

Another solution is to use \DeclareRobustCommand for the TikZ-based commands. This solution works for captions, but not for chapter titles. You can use the short title in this case: \chapter[Short for TOC]{Long description with $\join$}

Another solution for PDF bookmarks: \DeclareRobustCommand{\TikzStuff}{\texorpdfstring{\tikz\node{pgf};}{replacement text}}
