Fehler im Modelleditor bei mit Java implementierten dynamischen Label von Attributen
Man kann Attributen ein dynamisches Label als Annotation geben. Dies geht In-App, dann kann man ein Label per TLScript ausrechnen. Dies führt zu folgender Attributsdefinition:
<property name="Foo" type="tl.core:Double" > <annotations> <dynamic-label> <label> <expression>"Hello World"</expression> </label> </dynamic-label> </annotations> </property>
Wenn man die Berechnung des Labels jedoch als Java-Implementierung konfiguriert:
<property name="Bar" type="tl.core:Double" > <annotations> <dynamic-label> <label config:interface="com.top_logic.layout.ScriptFunction3" class="com.top_logic.mercedes_benz.aema.LabelInCurrency" /> </dynamic-label> </annotations> </property>
Kommt es zu einem Fehler im Modell-Editor, wenn man ein solches Attribut anklickt:
