Expanding and clarifying what BJD said; After you create the temporary sub-VI that BJD mentioned, open its front panel and copy the reference control that LV created when it created the sub-VI.
This reference control will be correct class etc that you need. Use the control to replace the original control that you were attempting to wire up. The technique of "create sub-VI...copy" always works for me. There is one more thing that you should watch out for. The mechanical action of the boolean can not be set for latch action when attempting to read the value using a value property node. Trying to help, Ben
