Change XControl direction: changing direction of child VIs

Question

Hi,
I'm writing an XControl containing several booleans, with a numert output based on which button is True, but I cannot change the direction of the Buttons when the direction of the XControl is changed in the VI using it:
In the owning VI, in Edit mode, I change the direction of the XControl via the drop-down menu.
In the XControl, the Direction Change event is triggerd, with {Indicator=True/False; RunMode=False}
I then set the Indicator property of the VIs in the XControl, but recieve an error (see below)
I also noticed this bug: wiring the error to an Error indicator on the XControl Facade yields:
Code: 1073
Source: Property Node (arg 1) in ControlSystem.lvlib:Filtermodes.xctl:FilterModes Facade.vi:31->ControlSystem.lvlib:Filtermodes.xctl:FilterModes Facade.vi.ProxyCaller
<APPEND>
Property Name: <b>Indicator</b>
Whereas a probe shows:
Error 1073 occurred at Property Node (arg 1) in ControlSystem.lvlib:Filtermodes.xctl:FilterModes Facade.vi:31->ControlSystem.lvlib:Filtermodes.xctl:FilterModes Facade.vi.ProxyCaller
Possible reason(s):
LabVIEW: This property is writable only when the VI is in edit mode, or this method is available only when the VI is in edit mode.
Property Name: Indicator
Also, one cannot call 'Explain error/warning' on Error indicators in XControls form the using VIs
How can I change the
direction of the buttons in my XControl to match the direction of the XControl?
TIA,
Jonathan

Answer 1

An
XControl dropped on a front panel (whether the FP is in an XControl or
not) is ALWAYS in run-mode.  It is essentially a parallel process to the
VI in which it is contained.
So even if the VI is not running, all the XControls
on it's FP are running?
I think this is the problem
when you are trying to set the direction in your code.
 This 'code' is the direction change handler in the XControl Facade, if the above is true, then I'm out of luck I guess
You want to set the direction of other
XControls contained within your XControl? Is this right?
Not exactly, I want to set the direction of normal control (Customized, but not an XControl), contained in the FP of my XControl, although it seems like that won't change much
Based on the comments LabView adds to XControls, it seems that the Facade is not running in between processing events, so maybe one could change the direction of the controls after the event handling is done (Some kind of callback)?
My current work-around is to disable my controls in indicator mode, since disabled Modern OKButton controls look identical to their indicator
