Description
This expression doesn't work :
[% attribute(@atlas_feature, 'Pop_Dpt_INSEE_POP_06')%]
POP_06 is a joined field from Pop_Dpt_INSEE csv table.
By the way, it's weird that simple quotes are required for field names in attribute function instead of double quote.
As a result, double clicking on a field name to insert it doesn't work...

Your expression is wrong. Just use
[% "pop_DPT_insee_pop_06" %]

You'll find answers at the end of this discussion. However,

seems a valid remark though it may not be easy to fix. Users can indeed be puzzled even though there's a help along the function. I think the QGIS doc should be full of this kind of subtle usage to help user be really aware of them (and the potential of the expression builder).

Thanks for the answers.
@Nyall : I tried with the field name alone, as you suggest, but it didn't work either. I also tried [% attribute($currentfeature, 'Pop_Dpt_INSEE_POP_06') %] with no luck. However, it works perfectly for normal fields (not joined).
@Harissou : Explanations in the discussion you linked to make sense. They helped me to understand the syntax.
But then, if the way to go is the field name alone, what is the purpose of the attribute function ? Former versions compatibility ?
