labview property node used in a subvi

[HEJ@WR]

I have a group of front panel Boolean control I would like to minipulate the visiblity and color(4) in a subvi.  I created a cluster of boolean refnum and passed them to the VI.  In the VI I created a cluster of CTLRefnum which I used as the input cluster.  In the subVI I am able to control the visibility via the visibiliy property node, however the Color(4) property node does not appear as a selection in the subvi.  Any ideas on how I could control the colors in a subvi.

Hello HEJ@WR,

It sounds like you may have cast your Boolean refnums to more generic Control refnums- as the Color property is specific to Booleans you'll need to ensure that you're maintaining the reference type.  Visibility is a more generic property that applies to all types of controls. Refer to this article for more information on casting refnums:

LabVIEWWiki also has a pretty good discussion of refnum types and class-specific properties here:

Also- if you attach example code demonstrating what you're attempting to do it's much easier for other forum users to assist!

Adding the "to more specific class function" in the subVI solved the issue.

Thanks,
