NPE when setting TextInputControlSkin's StyleableProperty for -fx-font

    Details

    • Type: Bug
    • Status: Closed
    • Priority: P3
    • Resolution: Fixed
    • Affects Version/s: fx2.0.2
    • Fix Version/s: fx2.1
    • Component/s: javafx

      Description

      The use case is to be able to reset the font that would have been set on a TextField/TextArea thanks to CSS.
      The general algorithm that is applied in this case is to:
      - Create the initialValue thanks to StyleableProperty
      - call textInputSkin.impl_cssSet(property, value);

      In the case of a Font, there is no initialValue and the Skin doesn't react well when null value is provided.

      WARNING: javafx.scene.Node impl_cssSet Failed to set css [StyleableProperty {owningClass: com.sun.javafx.scene.control.skin.TextInputControlSkin, fieldName: font, property: -fx-font, converter: FontConverter, initialValue: '', inherits: true, subProperties: ['artificial' StyleableProperty {property: -fx-font-family, converter: StringConverter, initialValue: null}, 'artificial' StyleableProperty {property: -fx-font-size, converter: SizeConverter, initialValue: null}, 'artificial' StyleableProperty {property: -fx-font-weight, converter: Font.WeightConverter, initialValue: null}, 'artificial' StyleableProperty {property: -fx-font-style, converter: Font.StyleConverter, initialValue: null}]}]
