<degrafa:LinearGradientFill id="bluedream">
        <degrafa:GradientStop color="#6ab5d0"/>
        <degrafa:GradientStop color="#388aae"/>
</degrafa:LinearGradientFill>

<degrafa:GeometryComposition graphicsTarget="{[bgCanvas]}">
        <degrafa:RoundedRectangle id="color_preset" fill="{bluedream}"/>
</degrafa:GeometryComposition>

I have issue with degrafa code which I have defined a set of different gradients for color_preset.fill to be dynamic change when user select different color in the combobox.

I replaced fill="{bluedream}" with fill="using_variable" and lead to error compiled message: Initializer for 'fill': values of type com.degrafa.core.IGraphicsFill cannot be represented in text.

Is there a solution to use this code as a color changer?
