Problem with merging frames with subdiagram label

[CLH239]

I noticed a problem today with using subdiagram labels in a flat sequence. If I merge frames in the sequence the labels come together and can't be deleted. If I uncheck Subdiagram labels from the visible items menu, the label stays there. Trying to select just the label selects the entire flat sequence.

Wasn't sure if this was a bug or not.

Thanks,

I see what you mean.  One more reason to stay away from flat sequence structures - unless they contain only one frame.  Yes, there actually is a use for a flat sequence structure with one frame.

Hi Chris, 

I took a look and was easily able to reproduce this incorrect behavior. This was reported to R&D (# 402433) for further investigation. 

Thanks for bringing this to our attention!

I've just hit this myself. Is there any update? Or any way to remove the surpurfluous label?

It gets worse when you enlarge the merged frame in both directions and you end up with a label across the middle of the frame stuck behind everything and impossible to remove.

Hello Hornless.Rhino,

You can check the current status of bug fixes for different versions of LabVIEW online. A list of bug fixes for LabVIEW 2013 SP1 can be found online at https://www.ni.com/en/support/documentation/bugs/14/archived--labview-2013-sp1-bug-fixes.html

As prevously stated by Any-C the reference number for this bug is 402433. At this time, the bug has not been fixed but you can keep checking on the provided website and subsequent versions of LabVIEW.

Didn't know about that page. Thanks.

I'm running LabVIEW 2014 with all the most recent updates and just ran into this exact problem.  Is there a fix or workaround yet or am I stuck with a giant immovable label in the middle of the Block Diagram?

The workaround is to not use a sequence structure 😁.

I realize that. I'm fixing up someone else's existing VIs and breaking down the massive flat sequences into something less terrible. But now I'm stuck with these huge glitchy labels. I will also point out that right-clicking one of the labels and choosing Properties (the only option) causes LabVIEW to immediately crash. Every time. So this is definitely a bug that needs to be fixed.

I have found that when cleaning up bad code getting rid of sequence structures is typically a 3 step process:

1 Convert stacked sequence to a flat one.
2 Remove the flat sequence.
3 Hit block diagram cleanup

Most of the time that is all that is required because there is usually already data dependencies between the frames.
