Description expression doesnt change in TestStand

[mitulatbati]

Hi all,

I have a Step Type in TestStand, which has an EDIT substep. I open it from teststand (with a special menu what I inserted), and cnahge the parameters of the step. When I close the EDIT.vi, I would like to see a parameter in the Description field in TestStand Sequence Editor. My problem is, that it does not change, the Description expression keeps the default value. If I see the parameter values in tree view in the sequence editor, I can see the changed parameter, but the desc.expresion is not updated.

On the attached screenshot you can see the setting of the step type, I think the Step_Description Expression is OK.

Why does not it update my Description field? I want to solve this, because in the future it can be very annoying.

Regards

Gyula

mitulatbati,

i am sorry since i cannot reproduce your issue. Here is what i done:
a) Create a custome steptype within the sequence. I've copied a PassFail for this.
b) Change the default "general"-tab exactly like your screenshot shows it.
c) Create a string-variable under the customized Step called "Command". If you want to use another variable-type, you have to cast it to a string by using str( <variable> ).
d) Create a VI for the EditSubStep and include it. The VI has to have a returnvalue (string) for the Command (Step.Command).
e) Create a Step within your Sequence using your customized step. Now the Description is "Command: ". You have to call the Edit Step now. If your EditSubStep-VI is finished successfully, the Description should change into "Command: <yourcommandname>".

Please check this. I used LV 8.2 and TS 3.5.
