Several %(expression) in org-agenda-prefix-format

[laurent.jucquois@posteo.de]

Hi list,

I'm trying to setup some custom agenda views that would be useful for my 
work but i'm unable to define a custom org-agenda-prefix-format with 
several %expression successfully.

My org-file is as follow:

* Pierre Dupond v. Belgian State
:PROPERTIES:
:Case: Dupond
:Location: Court of XX
:FiscalYear: 13-14
:CaseNum: 15/RG/139
:END:

** My first pleadings
DEADLINE: <2016-05-15 mon.>
** Pleading from Belgian State
** My second pleadings
** etc.

When I check my agenda, it doesn't serve me at all to see the general 
description "** My first pleadings" if I don't know to which case it 
relates.

So, I'm trying to setup a custom agenda view that would look like this:

Dupond 15/RG/139 (13-14) : My first pleadings

I've come up with the following (mal-functionning) 
org-agenda-prefix-format:

%(org-get-entry (point) "Case" t) %(org-entry-get (point) "CaseNum" t) 
%(org-entry-get (point) "FiscalYear" t)

But this only gives me :

Dupond : My first pleadings

I would really appreciate that someone points me into the right 
direction.

Thanks,

Laurent
