Hi,
Sorry I have yet another question. :( I am getting a weird error that I
simply do not understand, and I've been beating on this for a while now to
no avail.
I am trying to add a field to DslReference. I want the syntax to look like
this in the design file:
Entity Apple {
...
}
Entity Banana {
...
}
Entity Cantaloupe {
- @Banana banana [EMAIL PROTECTED]
}
I changed the DSL definition by adding the "foo" field:
DslReference :
(doc=STRING)?
REF (visibility=DslVisibility)? (collectionType=DslCollectionType"<")?
(("@")?domainObjectType=[DslSimpleDomainObject]) (">")? name=ID
((key?="key") |
((notChangeable?=NOT "changeable") | ("changeable")) |
((required?="required") | (NOT "required")) |
((nullable?="nullable") | (NOT "nullable")) |
("cascade" "=" cascade=STRING) |
("fetch" "=" fetch=STRING) |
((cache?="cache") | (NOT "cache")) |
((inverse?="inverse") | (NOT "inverse")) |
("databaseColumn" "=" databaseColumn=STRING) |
("orderBy" "=" orderBy=ID) |
("foo" "=" ("@")?foo=[DslSimpleDomainObject]))*
(OPPOSITE oppositeName=ID)? (";")?;
The transformation definition didn't seem to make any difference in this
problem, but here it is just in case:
create sculptormetamodel::Reference this transform(DslReference reference) :
setDoc(reference.doc) ->
...
setDatabaseColumn(reference.databaseColumn) ->
(reference.foo != null ?
setFoo(reference.foo.transform()) :
null) ->
(reference.oppositeName != null ?
setOpposite(reference.findOppositeReference(reference.oppositeName).transform()):
null);
When I run mvn-install, I get a bunch of transformation test failures like
this:

I looked in the GenChecks file and don't see anything different. Deleting
the transformation snippet makes no difference. I changed the reference
from "[DslSimpleDomainObject]" to String, and that passes the tests. I
changed it to "ID", and that passes the tests. I also changed it to
DslSimpleDomainObject without the brackets, and that passes the tests too.
But that doesn't do what I want because the editor doesn't recognize the
entity name properly. So I thought maybe something's wrong with using
DslSimpleDomainObject, and I tried DslEntity and DslBasicType. But those
don't work either. Oddly enough, I have gotten this exact syntax to work
before for this other definition:
DslConstant :
(doc=STRING)?
"const" (name=ID)?
("value" "=" value=STRING) |
("valueRef" "=" ("@")?valueRef=[DslSimpleDomainObject]))* (";")?;
So what is different about DslReference? What the heck does the error mean?
Thanks for all your help!
