Running afBedSheet sample produces "Service does not exist for Type 'afIocConfig::FactoryDefaults'" error

Question

I'm trying to create a new web application in Fantom programming language using the afBedSheet framework but can't get the simplest example to run.

The code is:

using afBedSheet
using afIoc

class AppModule {
  @Contribute
  static Void contributeRoutes(OrderedConfig conf) {
    conf.add(Route(`/hello/**`, HelloPage#hello))
  }
}

class HelloPage {
  Text hello(Str name, Int iq := 666) {
    return Text.fromPlain("Hello! I'm $name and I have an IQ of $iq!")
  }
}

And my build.fan looks like this:

using build

class Build : BuildPod {

    new make() {
        podName    = "mt"
        summary    = "TODO write a description here"
        depends    = ["sys 1.0+", "afBedSheet 1.0.16+", "afIoc 1.4.6+"]
        srcDirs    = [`fan/`, `test/`]
    }
}

When I run the command...

fan afBedSheet mt::AppModule 12345

...this is the error I get:

What am I missing here?

Answer 1

Ah, it seems the IocConfig module is not being added as a transitive dependency, hence Service does not exist for Type 'afIocConfig::FactoryDefaults'.

The quickest fix is to add the following to your build.fan:

depends = ["sys 1.0+", "afBedSheet 1.0.16+", "afIoc 1.4.6+", "afIocConfig 0+"]
meta    = ["afIoc.module" : "mt::AppModule"]

That is, add afIocConfig as a dependency and define your AppModule as pod meta. Then start BedSheet with just the pod name:

fan afBedSheet mt 12345

This is an issue with v1.0.16 when afIocConfig was split out into it's own pod - the tests passed because afBedSheet itself depends on afIocConfig. d'Oh!

This should be fixed in afBedSheet v1.1.0.
