Symbology - Size assistant bug

The excellent Size assistant dialogue for setting data-driven symbology properties generates an expression where the field name is not set into quotation marks. This causes the expression to not work. manually editing the expression, or adding quotation marks to the name of the field in the assistant is a workaround.

Hi Saber, thank for the report and sorry for the delay,

When do you witness the bug ? When the field name contains spaces ?

If the bug is with spaces, then the problem comes from QgsFieldModel and is propagated to QgsFieldExpressionWidget, it is also there when using e.g. the expression widget in classified symbology.

I wonder if QgsVectorLayers::fields() should add the quotes or if it should be done later (e.g. in QgsFieldModel or in QgsFieldExpressionWidget).

Denis: what do you think ?
