Mapper and Loggable

[Jonathan Ferguson]

 I know there is an answer to this, I can't find it and may brain is fried. 

class Example extends LongKeyedMapper[Example ] with IdPK with Loggable {

  def getSingleton = Example 

}

object Example  extends Example  with LongKeyedMetaMapper[Example ] 

 The above will fail to compile with the following error:

Example.scala overriding value logger in trait Loggable of type net.liftweb.common.Logger;  value logger in trait MetaMapper of type net.liftweb.common.Logger has weaker access privileges; it should not be private

Cheers

I found this thread that discusses the problem:
https://groups.google.com/forum/#!topic/liftweb/CRdzGyZa6vs

It has no real solution, just kind of an explanation (which you gave :)
)

Looking at MetaMapper, I found it has a private val logger, I guess
that's the culprit?

Instead of adding Loggable you could add:

private val logger = Logger(classOf[Example])

to your class. That should compile.

Oh dear :) 

Thank you.

I'll give it a go, thank you again.
