IF:
- The extrafield is of type "Select from list"
- AND it would use a join as table
- AND the label would be a concatenation of fields from both tables
THEN, the EF value could not be displayed (showOutputField os showInputField).
example of syntax that would trigger this error : `commande c INNER JOIN llx_societe s ON s.rowid = c.fk_soc:s.nom|c.ref:c.rowid::`
This commit fixes this.
