Hi everybody,

I have implemented a DSL with xtext but when I run it as Eclipse Aplication I am not able to see the correct outline tree. Each element has the name <unnamed> until the first one, like:

myDsl
<unnamed>
<unnamed>
<unnamed>
<unnamed>
<unnamed>
<unnamed>

What's wrong or have I forgot something? I only want the default outline tree, therefore the outline API is enabled

// outline API
fragment = outline.OutlineTreeProviderFragment {}
fragment = outline.QuickOutlineFragment {}

I am using XText2.2.1

Many thanks for your help,
Joe

Hi does you grammar NOT have name attributes at the places of the
outline nodes. Did you implement a label provider as the docs
suggest?

Hi,

thanks for this information Smile

. Now I have added to the MyDomainLabelProvider the following functions (as example):

String text(Class class){
   return "Class "+ele.getName();
}
String text(Function fun){
   return "Function";
}

Of course, as example now the tree looks like

Class [MyClass]
  Function
  Function

The problem is, that "Function" has no method getName() (fun.getName() does not work)

The name of the function is shown in the tree deeper. How can I put the name for the function to an upper level of the tree like:

Class [MyClass]
  Function [MyFunction1]
  Function [MyFunction2]

Many thanks,
Joe
