Description field can't be updated in BatchModel in TestStand

[StevenHuang]

I would like to see the test socket number in description field of interface in batch model in TS, I have done a StepType in attachment and the description expression what I set is:

RunState.TestSockets.MyIndex ==0 ? "TestSocket 0" : "TestSocket1"

But when I run it in batch model, the TestSock1 can't be update however ( it displays "TestSocket0").

Any help would be highly appreciated.

Thanks.

Couple things Steven,

1)- Your expression step in the ModelOptions callback has a double ==.  It won't set your testsockets to 2 like you want it to.  It will just evaluate it and say if it's true or not but not do anything about it.

2)- I tried "TestSocket " + Str(RunState.TestSockets.MyIndex)  and that didn't work either.  However, when you do "TestSocket " + Locals.MyDescription and then as a preexpression of the step set Locals.MyDescription = Str(RunState.TestSockets.MyIndex)  then it works.  Weird that it will grab the Locals and they'll work but won't evaluate the Runstate Properties. 

Seems kinda hokie.

Hi,

You probably needed to use the Evaluate function

ie Evaluate("TestSocket " + Str(RunState.TestSockets.MyIndex) )

Seem like "RunState.TestSockets.Myindex" is not available in "Description expression" of StepType, I tried it like Jiggawax described that put "RunState.TestSockets.Myindex" to a variable first in the pre-expression of a step, then use this variable instead of "RunState.TestSockets.Myindex" to evaluation is ok.

Is this a Bug?smileywink:

Ray and Jiggawax, Thanks for your help.
