Program won't build if a broken vi is included in a diagram disable structure

[Timmar]

I develop code that can run on both PXI and Compact RIO devices.

To allow for the different DAq methods I have a target specific child object that I tried putting in a conditional disable diagram.

I found that even if it was disable, the build would still fail.

When you build rio code on a pxi target, you et problems But I didn't expect them if the class was diagram disabled

In fact it won't build if it is in the project at all.

Posted as a bitter lesson for others to avoid.
