[Boost-users] Fw: Parser error from semantic actions

Hi,

How can I inform an error from a semantic action? Consider the following code:

rule = IDENTIFIER[ callback_a( m_varBinder, &VarBinder::bind ) ];

callback_a is an actor allowing member calls in semantic actions. 
VarBinder::bind receives an identifier and try to locate it in an external 
symbol table. If bind fails, I like to inform a parser error back to Spirit. 
How can I do that? Pointers to the relevant parts in the documentation are 
welcome.

Hermann
