	 *         Note: Filter can be a string like "(t.ref:like:'SO-%') or (t.date_creation:<:'20160101') or (t.nature:is:NULL)"
	 *  'label' the translation key.
	 *  'enabled' is a condition when the field must be managed.
	 *  'position' is the sort order of field.
	 *  'notnull' is set to 1 if not null in database. Set to -1 if we must set data to null if empty ('' or 0).
	 *  'visible' says if field is visible in list (Examples: 0=Not visible, 1=Visible on list and create/update/view forms, 2=Visible on list only, 3=Visible on create/update/view form only (not list), 4=Visible on list and update/view form only (not create). 5=Visible on list and view only (not create/not update). Using a negative value means field is not shown by default on list but can be selected for viewing)
	 *  'noteditable' says if field is not editable (1 or 0)
	 *  'default' is a default value for creation (can still be overwrote by the Setup of Default Values if field is editable in creation form). Note: If default is set to '(PROV)' and field is 'ref', the default value will be set to '(PROVid)' where id is rowid when a new record is created.
	 *  'index' if we want an index in database.
	 *  'foreignkey'=>'tablename.field' if the field is a foreign key (it is recommanded to name the field fk_...).
	 *  'searchall' is 1 if we want to search in this field when making a search from the quick search button.
	 *  'isameasure' must be set to 1 if you want to have a total on list for this field. Field type must be summable like integer or double(24,8).
	 *  'css' is the CSS style to use on field. For example: 'maxwidth200'
	 *  'help' is a string visible as a tooltip on field
	 *  'showoncombobox' if value of the field must be visible into the label of the combobox that list record
	 *  'disabled' is 1 if we want to have the field locked by a 'disabled' attribute. In most cases, this is never set into the definition of $fields into class, but is set dynamically by some part of code.
	 *  'arraykeyval' to set list of value if type is a list of predefined values. For example: array("0"=>"Draft","1"=>"Active","-1"=>"Cancel")
	 *  'comment' is not used. You can store here any text of your choice. It is not used by application.
	 *
	 *  Note: To have value dynamic, you can set value to 0 in definition and edit the value on the fly into the constructor.
