Error 1073 (property available only in edit mode) when I think my vi IS in edit mode

I have an Alphabetize.vi utility method that is a class member.  The VI alphabetizes the contents of a type def'd cluster using scripting.  The type def'd cluster is also a member of the same class. When I call Alphabetize.vi, I get error 1073:

As far as I can tell, the type def IS in edit mode.  (When I open the type def ctl file and select Operate, I only have the option to switch to "Customize Mode", which implies that I'm in edit mode.)  The type def's cluster is a part of my class's private data, which I have confirmed is also in edit mode.  However, when I remove the type def from my class's private data, I don't get error 1073 when I run Alphabetize.vi.

Is this a bug or an expected behavior?  I'm not understanding why adding the type def to class private data suddenly makes LabVIEW think the type def is in edit mode.

Thanks!

When a member of a class is executing the class is locked.

When you moved the ctl outside the class, it was no longer being locked and your code can run.

D'oh, that makes sense.  I moved the Alphabetize method out of the class, and that solved the problem.

Thanks!
