Actor Framework Message Maker crashing LabVIEW

[justACS]

Drat.  There was a known issue in the AF project provider in such circumstances.  This would be something I haven't seen yet.

It would be interesting to know if your problem follows if you switch to the project provider.

I'm not sure what you mean by "project provider".

The Actor Framework Project Provider

[BillMe]

I will install and try it. Hopefully it's fortuitous because my app is at the point where my next step is to create a lot of messages.

[BillMe]

So on my first try I got this:

Error 1026 occurred at Invoke Node in Actor Message Maker Provider.lvlib:Create Message Classes for Actor.vi:1700002->Actor Message Maker Provider.lvlib:Item_OnCommand.vi:7170001->Actor Message Maker Provider.lvlib:Item_OnCommand.vi.ProxyCaller

Possible reason(s):

LabVIEW:  VI Reference is invalid.

Rebooted. Tried again...same error. Happens as soon as I select "Create Messages for Actor".

The only invoke node in that VI gets all descendents of the selected library.  You shouldn't be able to select Create Messages for Actor if the object is not an actor, so I don't know why that would fail.

How big is your project?

[BillMe]

About 4MBs zipped.

And I opened the "Simple Actor Example" that I got from somewhere and the Project Provider works fine. So logic would say there's something about MY project that's causing the crashes.

That's what I'm starting to wonder.  As I intimated before, there is a known issue with methods that take classes as inputs - that introduces an instability that will cause a crash the *next* time you try to create a message.  That's getting fixed in 2015.  But what you're describing doesn't match anything I've seen to date.

Put together the smallest version of your project that exhibits the behavior, and a detailed description of how to reproduce it.  I will pm you with where to send it.  No promises, but I'll see what I can find out.

Another symptom:

I run Message Maker but don't actually build any messages. Close the window.Close the project.

and......

CRASH:

Possible Cause: C:\Program Files (x86)\National Instruments\LabVIEW 2014\resource\dialog\GSW\GSW.lvlibp\1abvi3w\resource\dialog\GSW\Classes\Feed_link\GetCachedFeed.vi

This happens everytime I go through those steps.
