**Issue:** Shared parameters written to Area elements via the Revit API (through Dynamo) show correctly in element properties but do not display in area schedules or area tags until a manual user interaction (clicking into a schedule cell) is performed.

**Steps to reproduce:**

1. Create a shared parameter (Number type) bound to the Areas category

2. Add it to an Area Schedule and an Area Tag family

3. Write a value to the parameter via Dynamo using either `Element.SetParameterByName` or `LookupParameter().Set()` with a native API transaction

4. Check the schedule column and tag — both show blank

5. Open element properties — value is correctly written

6. Click into the schedule cell and press Enter — value appears

**Expected behavior:** Parameter value written via API should display in schedules and tags without requiring manual user interaction.

**Environment:**

- Revit 2026.4

- Model hosted on BIM360/ACC

- Dynamo 3.6.1

Schedules (and really any view) don’t refresh unless a document refresh command is sent. Try a transaction.end and transaction.start node to the end of your graph.

Further to what jacob has indicated, sometimes even after a document has been refreshed you have to get the data/element you want to view again.

This is more if your working in python, but one to watch out for as a “just in case” thing as you may need to re-get the schedule instead of using the same one from a earlier node.
