Property Node Disable Doesn't work

[annamaet]

I have a series of Boolean Buttons in a cluster that I need to sequentially enable & disable (& grey) based on previous actions. When I code this, it will usually change them the first time I run the VI in a LabView session. But subsequent times it will run (with no errors), but not change the state.

Has anyone seen this, or now how I can make it change. I've put breakpoints in & know it is executing the command.

could you post a small example of this? This would help us greatly in answering your question. Thanks

Thanks for the suggestion to post a small example. In stripping down my code, I found it worked when all my extraneous code was stripped out. I found that there were a few cases where I had errors passed to the property nodes that I hadn't anticipated & therefore it wasn't executing the property nodes.
