I have the following view parameter on a view shiftPattern : [ {"dayName": "Monday", "shiftStart1": "08:00", "shiftStart2": "16:30", "shiftStart3": "00:00", "shiftEnable2": true, "shiftEnable3": true, "shiftNextDay3": true, "dayNumber": 0}, {"dayName": "Tuesday", "shiftStart1": "08:00", "…

getValue(shiftPattern[0]) returns [{dayName: Monday, shiftStart1: 08:00, shiftStart2: 16:30, shiftStart3: 00:00, ...}]

Interesting, so your code was getValue(shiftPattern[0])? I would have thought it would have needed to have been shiftPattern[0].getValue(). Either way, it looks like now you have access to your list of dictionaries and can do what you need to do now yes?

Yes, that was my code. shiftPattern[0].getValue()['dayName'] also returns ‘Monday’ as does shiftPattern[0].value['dayName']

I think @pturmel mentioned in another thread that any .getProperty() type functions can also be accessed via just .property and in fact the .property method is slightly more performant.

OK. Thanks for the follow up. I should be able to continue with the real work now!

Yes, here: [image] Send data from db to excel Ignition It is a shortcut. Like .quality above is short for .getQuality(). Jython automatically recognizes Java getters and setters that follow the NetBeans pattern and treats them as jython object attributes. object.getS…

Thanks, Phil, but why did this work from the script console, startDate = system.date.addDays(system.date.now(), -1) # Yesterday for testing. startDate false = False # Set the JSON value = Python value. true = True # ... and here. shiftPattern = [ {"dayName": "Monday", "shiftStart1": "08…

My guess would be because in the script console shiftPattern is a List of Dictionaries but in the expression it is a JSON string.

That would explain it. Have you any idea how to convert it in Python? import json json.loads(shiftPattern[0]) still gives Error_ExpressionEval("Error executing script for runScript() expression:<my function name>")

i doubt its cuz its "json", QVs come from tags or databases, [image] Transistor: view.params.config.shiftPattern are you getting these from a tag/db?

View.params object passing to script - error while accessing list dictionary item
