LabelSpec using ComposedText

Hello forum.
First of all, my composed text is working. Thank you. :-) But now I have one more question about ComposedText concerning labels.
I have a dynamic user interface. Its labels are added in the #postBuildWith: method.

aBuilder add: (LabelSpec label: aComposedText layout: aPoint)).

But this does not work. The comment of the LabelSpec says:
[...] Label values may be Strings, Texts, ComposedTexts, or Images. [...] In the case of textual labels, the style property tells the font to be used in rendering the label. If this property is set to #default, the current TextAttributes default font will be used. The other values currently respected are: #small, #large, #system, and #fixed.

It seems that I have to define my ComposedText in the TextAttributes, so I can use it as label.

aBuilder add: ((LabelSpec label: aComposedText layout: aPoint) style: #myComposedText).

Is this true or is there a mistake in the assignment without the style parameter?

Thank you for your answers.

Best regards,
Tom Grünewald

There's a subtle error in the comment. *In this context*, a ComposedText should not be thought of as a "textual label" but just as a VisualComponent. The LabelSpec can be any sort of VisualComponent. If it's anything other than a CharacterArray (Text or String), you want to set hasCharacterOrientedLabel: false.
