Missing StructureAspectDescriptor and ConceptPresentationAspect

Hello,

Since this happened now a few times and I don't understand what I did wrong here my question:

After a while working on my project I get an error from Language,java

Compilation problems

sceml\core\Language.java : Syntax error on token "new", ClassType expected after this token (line: 51)

sceml\core\Language.java : Syntax error on token "new", ClassType expected after this token (line: 54)

...

Somehow after Rebuild project/language there are parts missing.

I don't realy understand what I have to change to avoid that, since I don't get any other errors or warings from 'Check Language'

In case I manually complete Language.java it works until I rebuild my project

it is:

@Override
protected <T extends ILanguageAspect> T createAspect(Class<T> aspectClass) {

// AP: legacy part, must be migrated from switch: please use lang.descriptor mapping label
if (aspectClass == EditorAspectDescriptor.class) {
return aspectClass.cast(new EditorAspectDescriptorImpl());
}
if (aspectClass == StructureAspectDescriptor.class) {
return aspectClass.cast(new ());
}
if (aspectClass == ConceptPresentationAspect.class) {
return aspectClass.cast(new ());
}
return null;
}

it should be:

@Override
protected <T extends ILanguageAspect> T createAspect(Class<T> aspectClass) {

// AP: legacy part, must be migrated from switch: please use lang.descriptor mapping label
if (aspectClass == EditorAspectDescriptor.class) {
return aspectClass.cast(new EditorAspectDescriptorImpl());
}
if (aspectClass == StructureAspectDescriptor.class) {
return aspectClass.cast(new sceml.carla.tree.structure.StructureAspectDescriptor());
}
if (aspectClass == ConceptPresentationAspect.class) {
return aspectClass.cast(new ConceptPresentationAspectImpl());
}
return null;
}
