I simplified the grammar to look like this:
Model :
(documentation = STRING)?
handlerType = ID
name = ID
'{'
(
("remote" '=' remote = ID ';')?
& ("local" '=' local = ID ';')?
& ("user" '=' user = STRING ';')?
& ("password" '=' password = STRING ';')?
& ("branches" branches += ID (',' branches += ID)* ';')?
& ("options" '{' (options += ID)+ '}' )?
)
'}'
;
The test is green. I'll have a closer look at the actual value converters.
Serialization result is
cvs TestRepo { remote = "http://abc.org" ; local = "file://aLocalURL/" ; user = "hello" ; password = "hush-hush" ; }
which looks pretty much as I've expected.
Worksforme. The original exception was caused by a bug in the transient value service. Closing bug which were set to RESOLVED before Eclipse Neon.0. |
When applying a quick fix serialization fails for "documentation" (or so I interpret the message). With this grammar: ---- Repository returns build::Repository : {build::Repository} (documentation = DOCUMENTATION)? handlerType = ID name = ID '{' ( ("remote" '=' remote = URI ';')? & ("local" '=' local = URI ';')? & ("user" '=' user = STRING ';')? & ("password" '=' password = STRING ';')? & ("branches" branches += Branch (',' branches += Branch)* ';')? & ("options" '{' (options += RepoOption)+ '}' )? ) '}' ; And this input: --- cvs TestRepo { local = "file://aLocalURL/"; user = "hello"; password = "hush-hush"; } I have a validation rule that checks that "remote" is set to a URI. And a quick fix associated with this error. When applying the quickfix... This is what I get: --- org.eclipse.emf.common.util.WrappedException: org.eclipse.xtext.parsetree.reconstr.XtextSerializationException: Serialization failed <# of serialized tokens>: <EObject path> "<serializable fragment, starting from the end>": -> <possible reasons for not continuing> 26:BeeModel.buildUnits[0]->BuildUnit'aTestUnit'.repositories[0]->Repository'TestRepo': "cvs TestRepo { local = "file://aLocalURL/" ; remote...": -> Repository_DocumentationAssignment_1: Repository.documentation is not set. -> Repository_RepositoryAction_0: n/a 21:BeeModel.buildUnits[0]->BuildUnit'aTestUnit'.repositories[0]->Repository'TestRepo': "cvs TestRepo { remote = "http://abc.org" ; user = "...": -> Repository_DocumentationAssignment_1: Repository.documentation is not set. -> Repository_RepositoryAction_0: n/a 16:BeeModel.buildUnits[0]->BuildUnit'aTestUnit'.repositories[0]->Repository'TestRepo': "cvs TestRepo { user = "hello" ; password = "hush-hu...": -> Repository_DocumentationAssignment_1: Repository.documentation is not set. -> Repository_RepositoryAction_0: n/a 11:BeeModel.buildUnits[0]->BuildUnit'aTestUnit'.repositories[0]->Repository'TestRepo': "cvs TestRepo { password = "hush-hush" ; }": -> Repository_DocumentationAssignment_1: Repository.documentation is not set. -> Repository_RepositoryAction_0: n/a 6:BeeModel.buildUnits[0]->BuildUnit'aTestUnit'.repositories[0]->Repository'TestRepo': "; }": -> Repository_BranchesAssignment_5_4_2_1: All 0 values of Repository.branches have been consumed.

If there is documentation, but it is converted to an empty string by my terminal converted (which trims strings). i.e. input like /** */ I also get serialization errors.
