Question

Enumeration code looks like the following

package com.mydomain

object Market extends Enumeration {

  type Market = Value
  val ASX, LSE = Value 

}

I try to use as follows

import com.mydomain.Market._

.
.
.

if (Market.ASX == currentMarket) {
...
}

This was working when everything was in the same package. When I moved to a new package I now get

not found: value Market

Answer 1

If you import Market, you have ASX and LSE directly available to you. You don’t have Market.ASX available–that would be if you had object Market available, which is what would happen if you did import com.mydomain._.

Being inside package com.mydomain causes com.mydomain._ to be loaded just like you imported it, so that’s why you can say Market.ASX when you’re in the same package.

When you write code in a different package, you need to either import com.mydomain._ and then use Market.ASX, or import com.mydomain.Market._ and then use ASX.
