TppInspectorSelectionData - SelectionControllor is nil.

edited October 2012 in Component Writing

RB 14.06 Build 284.

I have a custom RB component. It has some properties that is a list of properties that is preceeded with a '+' sign in the report designer object inspector. These properties can be changed without problem. However some of the sub properties is also a list of properties preceeded with a '+' sign. When I try to change these properties I get the following error: "TppInspectorSelectionData - SelectionControllor is nil."

If I go to, for example, the reports 'detail band' and click on 'background1-gradient-style' without changing the value I can then return to my component and I can then change the sub properties without an error.

Any direction/help would be greatly appreciated.

    Hi Tommy,

    Are the expandable properties of the initial expandable properties
    (second + level down) published? For instance, take a look at the
    TppBandBackgroundSettings class inside the ppBands.pas file. The
    properties the inspector needs to access are published to ensure they
    are registered when created.

    Best Regards,
