Spotfire: How to use calculated value (dynamic item) in ironpython script?
You are headed down the right path.  You have to pass it to a document property.  You can't use the calculated value.
I'm using spotfire and ironpython.
I've created a calculated value  (dynamic item) to know max date that match a condition in my data. 
I also have a ironpython script to do some things and part of this script must use the date from the calculated value.
I'm trying to have python code to get the information from calculated value, but I'm struggling with it. 
I couldn't do it "directly", so, now, I'm trying a work around... To create a document property to receive the calculated value  and use this document property as enter parameter in the script, but I couldn't find a way to use calculated value as source of information of property document. 
So... Is there a way to use calculated value inside ironpython script (directly or linking its value to a document property and using this document property as script parameter)?
