Bind panic

[monopolly]

Description

Sorry guys, another issue) There is an issue about a go function's bind.

Here is a bind function

func (a *App) Bool(k string, v ...bool) (res bool) {
//...something here
}

here is a simple js call - its the right call of go function

Bool('key', true)

in Go I just ignore ...bool value but wails don't: panic: reflect: cannot use []bool as type bool in Call

To Reproduce

go

func (a *App) Bool(k string, v ...bool) (res bool) {
   if v != nil{
     return true
   }
  return false
}

js

let res = await Bool('key', true)

Expected behaviour

wails have to understand that bool is valid value for a go "...bool" slice

Screenshots

panic: reflect: cannot use []bool as type bool in Call

Thanks for reporting this. Just checking... If you name the function "Zool" does it still panic?

[monopolly]

no no, it doest't matter whats the name of the function

if go function has a lazy slice param, wails have to understand it

[leaanthony]

There's a good chance we aren't handling varargs. If you get rid of the 3 dots, does it still panic?

[monopolly]

no if I use simple []bool all is ok, just for lazy slices.

[monopolly]

"lazy slices" I just call them that) ...some

At the very least we should have a better error message

[monopolly]

my bet sorry)

[leaanthony]

I mean, we shouldn't panic, but show a better message 🤣
