What steps reproduce the problem?
If possible, include a link to a program on play.golang.org.
http://play.golang.org/p/AUK0RsmDNu
1. import text/template
2. parse template with a function whose argument is a chained node: {{.F (.G 42).X}}
3. execute that template
What happened?
template parsed without errors, but its Execute() function returned an error.
What should have happened instead?
the template should have printed the function's result - 42 in my example code.
Please provide any additional information below.
In text/template/exec.go, evalArg() needs to handle the parse.ChainNode case:
case *parse.IdentifierNode:
return s.evalFunction(dot, arg, arg, nil, zero)
+ case *parse.ChainNode:
+ return s.validateType(s.evalChainNode(dot, arg, nil, zero), typ)
}
