Strange "value not found"-compiler error

[Andreas Joseph Krogh]

Hi all, I have this code-snippet:

val stateParam: Option[ExtendedStatusState] = ExtendedStatusStateVar.get

var criteria = stateParam.map(state =>
   state.criteria.copy(endLocalDate = state.criteria.endLocalDate)
).getOrElse{...

 

Which throws this compile-error:

 

 

[ERROR] /home/andreak/dev/officenet_origo/frontend/application/src/main/scala/no/officenet/origo/frontend/lift/snippet/report/extendedstatus/ExtendedStatusMonthYearSnippet.scala:80: not found: value state 
[ERROR]                 state.criteria.copy(endLocalDate = state.criteria.endLocalDate)
[ERROR]                                                    ^

​

 

Any ideas?

Probably something to do with these issues, if that's any help to you...

     Hello,

  Would be nice to have something self-contained.

  What happened if you replace the argument expression with ???:

val stateParam: Option[ExtendedStatusState] = ExtendedStatusStateVar.get

var criteria = stateParam

.map(state =>
   state.criteria.copy(endLocalDate = ???).getOrElse{...

     Best, Oliver

     Best, Oliver

 

Here's a test-case:

 

import org.joda.time.LocalDate

case class Criteria(endLocalDate: LocalDate)

class TestFisk {

   var criteria = Some(Criteria(LocalDate.now())).map(crit =>
      crit.copy(endLocalDate = crit.endLocalDate)
   ).getOrElse(Criteria(LocalDate.now))

   def endLocalDate = criteria.endLocalDate.plusYears(1).monthOfYear().withMaximumValue()

}

 

Error:(10, 28) not found: value crit
        crit.copy(endLocalDate = crit.endLocalDate)

 

It seems it's the 

def endLocalDate

 

which is causing the trouble. I think this is a bug because the named parameter endLocalDate in copy() should be unambiguous regardless if there's a def with the same name in scope.

 

If I annotate the return-type of def endLoalDate it compiles fine:

var criteria = Some(Criteria(LocalDate.now())).map(crit =>
   crit.copy(endLocalDate = crit.endLocalDate)
).getOrElse(Criteria(LocalDate.now))

def endLocalDate: LocalDate = criteria.endLocalDate.plusYears(1).monthOfYear().withMaximumValue()
