[HELP] Error, Unknown variable or property name '', error. No Details???

Our production team ran some of our TestStand software when it froze. Upon exiting the report file contained only one error:
“Error, Unknown variable or property name ''. [Error Code: -17306, Unknown variable or property name.]”
This has not happened before with this test sequence.
Now I have seen this before, during development of other TestStand projects, but there are usually details of the unknown variable in the error. This one just has empty quotes! There are around twenty sequences called in this software. Is this a rouge error, a symptom of the freeze, or do we have an unknown variable issue in these sequences?

Hi Christopher,
As you say as part of the Error Message you should of had the Variable name.
With this freeze and if you had to force exit of the TestStand, it would seem that to get any report at all you must be doing some sort of 'On the Fly' reporting. If so, can you pin point what the test sequence was doing to try to identify the cause of the freeze.
Maybe you are obtaining the variable name dynamically and because of the crash this value was not obtained and therefore you were passing an empty string. Hence no variable name in error message.

Unknown variable or property name 'ReportFilePath'. Error accessing item 'Runstate.Root.Locals.ReportFilePath'. in TestStand

Hi all.
I was using Teststand 4.2 up to last week and upgraded to TS 2013. In 4.2 I was using the following to get the location of the teststand report:
Runstate.Root.Locals.ReportFilePath
but with TS 2013 this no longer works.. is the following error:
Unknown variable or property name 'ReportFilePath'.
Error accessing item 'Runstate.Root.Locals.ReportFilePath'. in TestStand - Get Property Value (String).vi->
I've tried the following now with no success:
RunState.Root.Report.Location
So my question is how can I get the location (path) of the report file during test programmatically please?
Please find enclosed a screenshot of the report config:
Solved!

Shashidhar,
Thanks for your help! With your tips, I finally got it to work. For anyone else trying to modify report names based on user input after the sequential process model sets the file name path I will re tell what I did:
Edit the Ni_RerportGenerator.seq plugin found in C:\Program Files (x86)\National Instruments\TestStand 2014\Components\Models\ModelPlugins\
You go into this file and add the step higlighted in Blue at that same location. Please see the expression I typed in the expression box. Setting Parameters.ReportOptions.NewFileNameForEachUUTStatus to true forces re-evaluation of the report name at the end of the sequentialmodel.seq.
Then you add a FileGlobal in the sequenatialmodel.seq. I called my FileGlobal ReportFileName
Then I added an expression in my test sequence that modified the the new FileGlobal I created:
Finally I updated the report options (Go to Cofigure>Report Options > Report File Pathname and under File/Directory Options select "Specify Report File Path by Expression" and I entered my expression. It appears that you can disregard the evaluated report file path error (box below) because your pathname won't be generated until run-time.
This worked well for me hopefully it will for others.
Thanks,
Marco

Why does DB_PLImpotExportProperties throw "Unknown variable or property name. (Error = -17306)"?

When I run GenericImportExport.seq, the call to DB_PLImpotExportProperties brings up the Import/Export dialog. When I copy that step into my existing sequence, the error "Unknown variable or property name. (Error = -17306)" is thrown. I can see no difference between the two. They also appear to be running in the same environment.
Any suggestions?
Solved!
Go to Solution.

So this was bothering me enough that I went back and recreated the problem. I cannot even call the entire sequence without getting this error.
I added a step to my test sequence that makes a call to the sequence GenericImportExport.seq in a separate file (where it was installed). Right-clicking on the the step and selecting "Run Selected Steps" causes the subject error.
I CAN use the tool menu "Import/Export properties..." or open the sequence itself and run ImportExport without a problem.

"sCode=0xffffbc66: Description: Unknown variable or property name 'ReportStyle'. Error accessing item 'ReportStyle' when trying to optn the ReportOptions in TestStand 4.0.

I get the error "sCode=0xffffbc66: Description: Unknown variable or property name 'ReportStyle'. Error accessing item 'ReportStyle'. when trying to load the ReportOptions in TestStand 4.0.
Has anyone seen this before? If so how can I get around it as I will need to disable Report Generation for this system.
Thank you

Hello,
I am not 100% sure how I resolved this issue as it was a few years ago. However, I have attached the TestStandModelReportOptions.ini file that I used - hope this helps you.

Hi,
Open your sequence file in the Sequence Editor.
Select the Sequence that you wish to add Locals to, and make this the active sequence i.e the one thats visible to you, Usually it displays the MainSequence when first loaded.
Select the Locals Tab
In the right hand side of the display, there will be the variable ResultList.. This will be an empty array of Result.
Place your cursor in this position of the display and press the Right Mouse button. You will see an a popup menu of which the Top Item is Insert Local.. If you select this you will get an other set of options which are the different types of Variables that are available to you. Select a variable type, such as a Number. This will be inserted into right hand side under the ResultList array. It will be highlight ready for you to enter the name of the variable. If you double click on the variable you will get the Properties Dialog. You will beable to a new value.
The User Manual, should beable to explain on this.
I would recommend trying to get on the Basic TestStand course.
hope this helps

Error code -17306; Unknown variable or property name.

What does this error code mean in Test Stand, And what are solutions to this problem

Hi Reiter,
There are many reasons for this error as Nick has pointed out.
I have attached an example illustrating a typical situation.
One of the steps tries to read the value of a boolean in Locals of MainSequence. An error -17306 is generated if the boolean is not present.
The first step in Main gives you the option to skip or not skip the next step in the sequence.
The next step writes True to Locals.MyBoolean. (not this step has the option 1 - Insert if Missing)
The following steps Reads the boolean Locals.MyBoolean.
Hope this helps to resolve your problem

I get the above error when trying to deploy from Windows 2000 to a Windows XP professional?

Hi,
Have you got the ProcessModel sequence file "SequentialModel.seq" on you Deployed system.
You should find it in "TestStand\Components\NI\Models\TestStandModels" folder or "TestStand\Components\User\Models\TestStandModels" folder.

Unknown variable or property name stationGlobals.Revision

I am having problems with a stationGlobals variable on one deployed system in the field. I stop on that step on the development system and the deployment system here in the lab and the variable exists.
On the system having the problem the station options was not pointing to the correct location for the stationGlobals.ini. So I had them change the cfg preference and sent them a copy of the stationGlobals.ini file. They rebooted the system but the error persists.
Sure would appreciate your thoughts on this.

Thanks for the post. It turns out that the .ini file was overwritten when the station options were changed on the deployment system. They were changed to alleviate the problem I addressed in my Station options not copied to deployment post.

'Unknown variable'-error in TSIviStepType: Uses the german bolean value 'Falsch' instead of 'false'

Hi
I had to install MSVC onto a working test system. This is a PII/450 with 450MB RAM, running a german W2kSP2 and NI-SW from the english DevSuite Prof Test Edn, amoung others LV7.1, TS3, Switch Executive (SE) 2.
I had to install a german MSVC6 for debugging purposes. Its installer asked me for permission to replace some ressource files with german ones, which I -of course- denied. Nevertheless after this installation my TSIviSteps generate an error with a language-related problem:
Error executing substep 'Post'.
An error occurred calling 'RunStep' in 'ISubstep' of 'TestStand Ivi Step Types'
An error occurred while executing the step.
TestStand IVI Step Type Error:
An error occured when evaluating the properties of the step.
Details: Unknown variable or property name 'Falsch'.
Error accessing item 'Falsch'. - Wait for Debounce
Source: TSIviStepTypes
-17300; Value invalid or out of range.
Any easy solution? There must be a simple ressource file to be replaced. I'd dislike the idea of re-installing TS. BTW, Re-installing all the drivers and SE did not help.

The error you are seeing is because of a problem in the code for the TSIviSteps.dll. The code is written with Visual Basic 6.0. The error only occurs for the "Wait for Debounce" setting, which is only used for the Switch Executive Connect/Disconnect operation. Internally there is a cast of a boolean value stored in a step property to a string expression value. If the OS regional setting selects a non-English default language and the corresponding VB6xx.DLL (language resource file) is available, the MSVBVM60.DLL casts the boolean value to a localized string value. So for a German OS, if the VB6DE.DLL file is available the cast returns Falsch or Wahr instead of False or True. When TestStand tries to interpret Falsch or Wahr as a constant expression it
errors as described. The problem exists in TS 2.0.1, 3.0 and 3.1.
The workaround is to either remove the VB6DE.DLL language resource file or change the default language to English. We hope to fix the cast code in a future release.

Step_description unknown variable error in built operator interface

I'm getting the following error when I execute a seq. from a built LabVIEW operator interface:

Some searching is leading me to an issue with the localization languages files? Not sure what exactly.

Here is a guess: try right clicking on the step list and select a different step list configuration. If the problem goes away, then your current step list configuration has a column specified by expression and there is a problem with the expression.

Error: unknown state or association

hi:
I want to call a jpql sate ""select model from Webusercontact model where model.weblogon = :firstParam", I don't think there is the syntax error for the statement, but it allways displays: " Error compiling the query [select model from Webusercontact model where model.weblogon = :firstParam], line 1, column 52: unknown state or association field [weblogon] of class".
I am new for JPA, could I get any help?
I use myeclipse, the class Webusercontact is built by system, it also creates the classes: WebusercontactId, WebusercontactDAO, IWebusercontact, AbstractWebusercontact and EntityManagerHelper.

"weblogon" must be the variable or property name for the class (not the database column name). Perhaps include your class.

Undefined variable or class name

I am trying to call a java class to another class but gets the error: "Undefined variable or class name"
Both my java files are in the same directory and I am able to compile only one of the program. Wondering what am I missing?
The source code is:
ServletUtilities.java: (I am able to compile)

Report data binding error unknown column name

Hi,
I am having a problem with the new 7.02 update of Report
Builder. The issue is it's not finding my SQL query.
I have wrote my query initally in the advance mode, and it
doesn't seem to reconize it. Is there an issue with this?
I did manage to fix one of my reports by using the basic mode
and selecting all my tables and seting my linkage and criteria.
I have other computers that i have not updated to 7.02 and
they do not have this issue. Below is the error:
Error Occurred While Processing Request

This report works in 7.01. So all query variables match with
a variable in the SQL select statement.
Anyone have any Ideas??
Thanks,
Daniel

Thank you very much for help.
The "Unknown column name " is a field still used in my
report, so I can't remove it.
After I clear the query in the report and reopen the report
and apply the same query back to it, I get different error message:
Element TASKNUM is undefined in QUERY.
The error occurred in : line 1
-1 : Unable to display error's location in a CFML template.
I know for sure this "Element TASKNUM is undefined in QUERY."
is defined in query. each time it complains something different. I
get really confused.
Thanks again.
