I've been seeing strange behaviour when I modify the private data control of a class, especially if it is a parent class. It seems that those changes are not always propagated to all the VI's in the project. This sometimes causes my project to crash with an exception error, or sometimes the problem is more subtle as it will simply write data to the wrong elements in the control (when bundling/unbundling). I solve the problem by opening the typedef or class control by itself (i.e. not as part of the project), and then saving it. The next time I open the project all problems are solved. This is a difficult error to track down but I now know to keep a list of typedefs or class controls that I have modified (using subversion helps here), and then when this strange behaviour or crashes happen, I simply close the project and open each modified typedef or class outside of the project and save them individiually. Anyone seen something like this too?

LabVIEW crashes when modifying OOP parent class private data control or typedef contained in that control

I have similar experience.

I found that when I open only the class and modifie the class private data I can do mass compile before I save the changes... Then the private data are chenged without crash.
