When trying to add refactor fields to a model, the following error is thrown at the user:

I cna't confirm this on master/osgeo4w. Anyway I have seen this (once) when trying to edit the refactor field alg already added to a model
Traceback (most recent call last):
File "C:/OSGEO4~1/apps/qgis-dev/./python/plugins\processing\algs\qgis\ui\FieldsMappingPanel.py", line 144, in rowCount
return self._mapping.__len__()
AttributeError: 'NoneType' object has no attribute '__len__'

@Matthieu - I just tested with a recent master and it seems to work ok. I have other issues with expression context - Matthias is working on it - but other than that I can run a model with a "Feature Source" and connect it to the "Refactor Fields" algorithm.

Sorry, I should have mentioned that the error occurs when the algorithm is added in an empty modeler (i.e. no feature source / vector layer input yet)
Steps to reproduce- Create a new model
- Add the refactor fields algorithm
- You'll get thrown an error stack
