Hi I am getting a wrong number of arguments (4 for 1) error when  
render\_template is called for the  
auto\_complete\_for\_demerit\_slip\_std\_name action (which does an inline  
render (render :inline =\> “\<%= auto\_complete\_result @items,  
‘#{view\_method}’ %\>”)):

Processing  
DemeritSlipsController#auto\_complete\_for\_demerit\_slip\_std\_name (for  
127.0.0.1 at 2007-05-14 11:10:46) [POST]  
Session ID: 213f674068cde2f579f46472f07cf709  
Parameters: {“action”=\>“auto\_complete\_for\_demerit\_slip\_std\_name”,  
“demerit\_slip”=\>{“std\_name”=\>“b”}, “controller”=\>“demerit\_slips”}
