I have created a script where I have defined the method for converting a string into date. Now, I want to use this script in an expression binding for a label using "runScript()" function. I want to pass the text of this particular label into this runScript as an input, but I am getting an "Error_ExpressionEval" error. Attached below is the screenshot. Can anyone help in solving this?
Hover over the error?
Hi, thanks for the reply. If I hover over the error, I am not getting any error message
Look at your gateway log to see if anything shows there. If not, consider adding a try: -- except: block in your called function to capture and log any errors in the script itself.
It might be too late now, but I'd also suggest to have a look at the Python naming conventions PEP 8 – Style Guide for Python Code | peps.python.org
Generally:
- classes use
PascalCase - functions, variables, and library names use
snake_case - constants defined at the top of script libraries should use
ALL_CAPS(and should never be modified from their init value)
jython is so dominated by the JVM it sits in that I prefer java's camelCase for functions, methods, variables, and libraries.

Wouldn't this create an infinite loop since you're passing the text value of this binding into itself as a parameter of your runScript? Are you intending to use a different value from some other component to pass into your script instead?

@Visveswaran_Dharmara the answer to your question is yes you can pass in parameters
as a test, I made this quick function:
Then in a perspective view custom property binding I did this:
I would suggest you look at your actual function definition and make sure the issue is not there.
RE: style
I'm in full agreement with @pturmel there is so much in Ignition that is built on java that you cannot control so camelCase is the way to go to avoid having a messy mix.
Cheers,
