| Label Provider not being invoked [message #1844535] |

I customised the label provider for my DSL, but in the outline tree I don't get the labels I customised. While debugging, my custom methods never get called.
During debugging, I noticed that when creating nodes, OutlineTreeProvicer#_text IStyledLabelProvider#getStyledText
Is this the intended behaviour? How can I get the styled label provider to use the custom getText methods? I see doGetText called, but not the getText ones.

Thanks for the reply.
There is no exception, just the labels I defined not being used.
The org.eclipse.xtext.ui.editor.outline.impl.DefaultOutlineTreeProvider._text(Object) is the method I am looking at.
Is there some additional binding I need to do in the UI Module or else where? I think what I am missing is the part that does the dynamic dispatch to the specific text(XXX ele) for the ele's class.

_text(Object) is called.
What is not working is that that method does not in turn call the String text(<Rule> ele) methods (I understood you gave to implement the text(<Rule> ele) method for each node that you want to customise)

of course it does not as it calls
MyDslLabelProvider.text(Greeting) line: 27
NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not available [native method]
NativeMethodAccessorImpl.invoke(Object, Object[]) line: 62
DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: 43
Method.invoke(Object, Object...) line: 566
PolymorphicDispatcher<RT>.invoke(Object...) line: 303
MyDslLabelProvider(DeclarativeLabelProvider).doGetText(Object) line: 52
MyDslLabelProvider(DefaultEObjectLabelProvider).doGetText(Object) line: 36
MyDslLabelProvider(AbstractLabelProvider).getStyledText(Object) line: 122
MyDslOutlineTreeProvider(DefaultOutlineTreeProvider)._text(Object) line: 276
why does the reflection in doGetText not work for you?

That is what I am trying to figure out! hehe.
MyDslLabelProvider.text(Greeting) line: 27
never gets called.
The line called in MyDslLabelProvider is line 72, Object text(Object element), so its like the runtime dispatch is not working for some reason

Hi,
It somehow resolved it self. I think it was linked to an imported metamodel not being found at runtime (i.e. EPackage not registered exception). Perhaps the label provider logic catches the exception and just returns null.
