Summary0003610: App::PropertyFloatList not updating in Spreadsheet

When referencing a property of type App::PropertyFloatList from a cell in a spreadsheet the spreadsheet does not get updated when the property changes.
Steps To ReproduceTo recreate:

Create a feature python object and add a property of type App::PropertyFloatList to it. Add 3 values to it using the property editor: 0.0,1.0,2.0. Create a new spreadsheet. In cell A1 enter the reference to one of the floats in the property list. Update the list. Spreadsheet cell does not update.

Create the feature python object:

obj = App.ActiveDocument.addObject("App::FeaturePython","test")

Open "float" property (click the ... in the property view) and add 3 values:


Create a new spreadsheet. In cell A1 enter
Code: Select all

= test.float[2]
Cell A1 now shows 2.0 (all good so far)

Open the "float" property again and change it to:


Recompute the document.
Expectation: spreadsheet cell A1 updates to 2.2, but it doesn't update (stays at 2).

This same technique works with PropertyFloatList items when referencing from sketcher constraints and from other properties, so the change signal is getting emitted when the property changes. The signal that the float list property was updated is either not being received by the spreadsheet module or isn't being acted upon.
