compile failure on generated code

[uwesimm]

hi,

running scalaxb on the schema below leads to several issues. initially its that the generated code contains duplicated declarations for "attributes" such as the one below.

any hint ?

/uwe

case class MetricsPort(name: String,
  attributes: org.uwes.vplan2odf.vplanx.AttributesType,
  mappingPatterns: org.uwes.vplan2odf.vplanx.MappingPatterns,
  attributes: Map[String, scalaxb.DataRecord[Any]] = Map()) {
  lazy val id = attributes.get("@id") map { _.as[String] }
}

Try param prefix to work around it.

[uwesimm]

hi,

adding –param is adding a prefix to every member. so that doesn’t solve the issue.

case class MetricsPortType(param_name: String,
param_attributes: org.uwes.vplan2odf.vplanx.AttributesType,
param_mappingPatterns: org.uwes.vplan2odf.vplanx.MappingPatternsType,
param_attributes: Map[String, scalaxb.DataRecord[Any]] = Map()) {
lazy val param_id = param_attributes.get("@id") map { _.as[String] }
}

It's a bug of scalaxb it seems.

[etitov]

hi,
I have the same problem.

The problem can be solved

1. change ATTRS_PARAM to "tagАttributes" or whatever
2. make ATTRS_PARAM parameterized
3. scalaxbAttributePrefix affects the renaming of ATTRS_PARAM in generated code

I can fix it. What to choose?

[eed3si9n]

Whatever works is fine by me. 3 sounds least surprising?

[etitov]

when set scalaxbAttributePrefix := Some("a_")

case class MetricsPort(name: String,
  attributes: org.uwes.vplan2odf.vplanx.AttributesType,
  mappingPatterns: org.uwes.vplan2odf.vplanx.MappingPatterns,
  a_attributes: Map[String, scalaxb.DataRecord[Any]] = Map()) {
  lazy val a_id = a_attributes.get("@id") map { _.as[String] }
}

but now the parameter only affects class variables like id
I will try to make a pull request with 2 or 3 options

[etitov]

the problem can be solved by the parameter scalaxbNamedAttributes := true

case class MetricsPort(name: String,
  attributes: org.uwes.vplan2odf.vplanx.AttributesType,
  mappingPatterns: org.uwes.vplan2odf.vplanx.MappingPatterns,
  id: Option[String] = None)

[eed3si9n]

I don't remember why I defaulted that to be false. I vaguely remember they merge in some unpredictable way when types extend one another. Maybe it's also to do with the whole 22 limit thing. Either way, it's good to know of a workaround when it works though.

Fixed by @etitov in #558
