I'd like to build a property for an XControl in order to get the references of the controls in the facade front panel, something like the cluster "Controls[]" property. I tried to get the references from the facade and pass them to the main VI through the Display state and a property to read the values, but when I pass the refereces obtained in this way to a property node I get an error 1055 saying that the object reference is invalid. Thanks

-- couldnt edit my other post -- if you run your main.vi (which contains the xcontrol(s)) a red lock symbol appears on the then running xcontrols. right click --> "unlock library for editing" (and/or read "why is library locked?) after editing right click --> "apply changes to instances" good luck

Elements in the state cluster are only saved if the State Changed boolean is changed to true, like jwscs said. I would suggest moving the bundling into the Display State Changed event and then also writing true to that element. A quick test shows that this works. That said, you should consider whether you really want to expose reference to internal controls. The whole point of XControls is to hide the implementation. It might be preferable to add the relevant methods or properties to the XControl itself.

hi daniele88, unfortunately i don't konw the answer to your problem, but may i suggest putting a minimal version of your problem in code and link it here, that might help ppl troubleshooting (in case it is not something obvious why it wont work) the only thing i can suggest off the top of my head, is to make sure you have the "data changed" or "state changed" set "correctly" so the information is properly stored, to be accessed by the xcontrol-property but that might not be it. good luck
