Upgrade to 8.5 breaks project

[ibbuntu]

Hi,

I upgraded to LabView 8.5 on Friday. Had a quick play with it, opened my project from 8.2.1 had a look at some of the new oop features. Then closed it and saved it. Now when I come back to open it again this week Labview crashes on opening it saying: "Fatal Internal Error : "LinkObj.cpp" line 714". I also can't open the project in LabView 8.2.1 now as it says that the file version is later than the current labview version.

So I tried creating a new project in 8.5 and filling it with all my old classes, however this doesn't work as on adding the old classes LabView either crashes or the class is locked and it is apparently not loaded.

Here's the error log created when trying to open the project in 8.5:

It turns out it was a known bug. The fix was:

"The first time you load the private data control in 8.5, open the front panel and resize any control in the private data cluster before saving. This puts a change on the VI so the class knows to update the save image."

I'm now (finally) enjoying the new features in 8.5 and using a lot more accessor methods, which I tried to avoid like the plague as it was such a hassle before. Whether this is a good thing or not I don't know (see http://www.javaworld.com/javaworld/jw-09-2...5-toolbox.html)
