Creation of properties of Xcontrol - error

[ceties]

Hi all, I just started with Xcontrols. I am trying to create my own Listbox and I don't want to have all the properties code in "display state change" of Facade.vi. So I put a reference of the Listbox into State 1.vi because I thought that this way I could change the properties of the control in the property Vis. But I still get "Object reference is invalid" error. Why? I initialized the reference in "Exec state change". So Why? Thank a lot guys!

ceties,

This method of having a control reference as part of state information is not something I've seen attempted before. The file that you posted didn't seem to include any of the property VI's that you refer to.  Could you include an exampleof one of these property VIs?

Thanks for the reply. It's solved already. I cross posted it to LAVA forum.

tcplomp answer: In the 'Exec state change' you should set the 'State Changed?' boolean in the 'Action' cluster to true.

Reading my own post I realized that I have posted wrong link. This is the right one
