Using Array of Clusters in UTF

StevenGarcia — Fri, 04 Dec 2015 18:12:02 GMT

I need to put this out to the community. It seems that we are having issues using an array of clusters with the UTF for LabVIEW 2015. The UTF does not recognize these types of structures correctly. Attached is a file with screenshots showing the before and after.

It's a bit difficult to follow along in the Word document, so I'll try to summarize what I think you're experiencing here:

You have an array of clusters ("Array"). When you add another array of clusters ("sbRIO Data in"), the testcase prototype for the first array of clusters changes to add a value for the array itself (and not just the elements of the array.
You have an array of doubles ("Distributed P (kW)"). When you add an array of clusters ("sbRIO Data in"), the testcase prototype for the array of doubles changes to add a value for the array itself (and not just the elements of the array.
The added array of clusters ("sbRIO Data in") isn't captured correctly. Each element is represented by the first value of the cluster element, instead of the all of the cluster contents.
It looks like the lvtest file on disk is right.

This looks like a parsing bug to me - the UTF saves the lvtest correctly, but then doesn't read it back in correctly.

Silly suggestion: can you try again, but get rid of all the parentases in your control label names? The parser may be choking on these (it's just a hunch).

It would also help if you can upload the lvtest file and the VI you're trying to test (no need for any dependancies, you can even strip the code out if you like), as well as any Setup/Teardown components.

It seems to be the 'reading in' parsing that is not working in the UTF but also the file is modified incorrectly when the unit test is closed. What you explained is correct with regards to the screenshots in the Word document. I have attached the VI and the lvtest file that I was using but the VI and the lvtest file represent the VI without the 'sbRIO Data in' control connected to the connector pane. Once this control is attached to the connector pane and the test is updated, that is when it breaks. I wanted to try several types of arrays but it is the cluster array that is causing the most grief. I also removed the parenthesis from the control names, just in case.

Chris,

You were correct. It is a parsing issue and the problem was a control with "/" in its name. If you want to see how I got to that conlusion, see the video below.

I will contact NI to get a CAR filed as to why the dialog that informs us of the problem is not showing up in the original VI. Also, it would be interesting to know what changed from the previous version of UTF and the 2015 version that caused this to be an issue.

I'd figured it was parsing - that's what happens when you use plain text, without schema, as a configuration file format.

A CAR has been filed CAR # 564417.

The only thing we can do is to wait and see if it gets fixed in future versions.

Re: Using Array of Clusters in UTF

CAR 564417 has been fixed in LabVIEW 2016. Please see the LabVIEW 2016 Bug Fix List for more information.

Special characters in Control names can cause Unit Tests to not recognize cluster elements in some cases.

A control with a special character (/) in its label can cause an lvtest does not to show the controls in a cluster.

Does this mean that all characters that UTF allows to be entered in its UI will be saved and read correctly? Of you just fixed it for the "\" case?

Re: Using Array of Clusters in UTF

Craig_ — Mon, 08 Aug 2016 15:17:34 GMT

Honestly you may have to test it.

Internally the CAR mentions just fixing the / character in control names, but the related parsing functions have UTF in their VI names, so it may work for more charachters

So you're telling us that the issue is fixed for at least one specific special character. For any others, maybe, who knows? Maybe we'll run into the same issue later on another character and you might patch it for that one later. Maybe.

Can you please spend a few minutes talking to the developer and find out the real story for us?

Christopher, I'll follow up with the developer, but it might take a couple days. Will that be sufficient?

I grabbed a VM and did some testing.

This prompt comes up when there's unsupported chars:

For the \n \r and \t codes I used the \ codes display of a string, put the code in, switched the control to normal display, copied the text into a label, saved, and opened the UTF for the VI to see if they caused any errors.

These things appear to work in labels:

\n (newline char)
\r (return char)
\t (tab char)
/ (forward slash)

These things cause the prompt

[ (left bracket)
] (right bracket)
\ (backslash)

What else would you want tested?

Does this answer your question?

Sure, that would be great.

+1 for your username, btw.

I think you're missing my point - I'm not looking for a lookup table of characters that the UTF supports, I want to know if this statement is true or not:

"The UTF will not allow the user to use characters that it does not support. It will also prompt the user if they attempt to use characters that it does not support."

Christopher, I wanted to let you know that I'm still digging in to this but I was unexpectedly out of office and haven't had a chance to explicitly confirm things.

Also, +100 for you if you caught my intended reference without googling: http://www.rally-maps.com/Rally-in-the-100-Acre-Wood-2013/Ollie-s-Camel

Even if you googled, +1 back at you for being a rally fan. Thanks, Chris

Christopher,

My apologies for the extended response time, but there's still a bit of a bug and also a time zone difference with the developer I've been interfacing with.

I have spoken with the developer and also validated their response. To be clear, if you right click on the VI in the project and create a new unit test, you can use any character in the control names, as illustrated here:

That being said:

You CANNOT right click on "My Computer" in the project and then modify the resulting blank test. It will still present the dialog box seen in former releases and will not parse the control names correctly. I had been using this approach to verify what the developer told me and was not seeing the behavior they described. (The had been using the method above.)

I appreciate your patience with this, and can post the follow up CAR for the second behavior mentioned once it is available. We'll be clarifying this on the current Known Issues List once the new CAR is available and publishing the new CAR on a subsequent Bug Fix List when it is resolved.

Righto, thanks for letting us know Chris. I'm glad that we bugged (ha!) you to get it checked out then

Well,

If you select examine, the info in your box will show: A camel who wants to fly some day.

The Ollies Camel stage is known for it's very large (for North American Rally) jump that causes the cars to go flying, so maybe there's a connection?

(Admittedly, this guy didn't get a good jump in. I cut him some slack for missing a wheel.)
