Some other comments

Prediates How-to in Guvnor :

You can use predicates in the dialog box for editing a condition column. There are 3 radio buttons for "value", "formula", and "predicate"

Templates VS tables :
Template are more flexible ... may be ... may be not.
First, in templates in guvnor, you first see the templated DRL, and you have to click on a button to edit the table. Businnes users don't care about the template, and want to see the table first
Second, in guided tables, you can set some constraints that are not added if the parameter is not set (empty cell). In template, an empty cell results in a empty substitution, and generally in a compilation error ... Template should incorporate a condition to put a bunch of the template if the cell is filled or not, or make all cells mandatory.

But I agree that template offer more possibilities (in term of rule complexity) that tables, which must handle "flat" POJO. For you initial question, ie using functions in tables, the simpler way is to add a method in the POJO itself, but may be not the cleaner way ... Indeed, using tables often lead to some model adaptations...

Ideally I'd like to implement "tabular templates" where a column can be any DRL fragment with place-holders for values and the data is listed in the rows below. It's on the "to do list".

If the template limitation you mention is causing problems please raise a JIRA and we can look into changing the behaviour.

Langages :
You can switch the langage used by adding "?langage=fr_FR" parameter to the guvnor URL.
You can also provide a resource file translated to your favorite langage (by browsing the trunk or a grep code) in a JIRA.

As from 5.3 we also set the locale automatically (from the browsers Accept-Language setting in Guvnor.jsp (which is set as the welcome page in web.xml too). Guvnor.html remains.

POJO upload :
You need to "SAVE" the package (File/Save in the package tab) after an upload for the new class to be updated (and old one to be deleted). "Verify" is not enough (was in 5.1, not in 5.2)

5. If I upload something from Eclipse it lands under "Other assets,
documentation" even if they are Java classes which I hoped would land under
Model... is there anything I can do about that? A Java POJO model once uploaded
is just a jar blob afterwards, not usable from Eclipse anymore...

Via Webdav it (should) works if you upload a .jar file. Works in 5.2m2 for me, but you still need to save the package (and create the import list in the package view too, or upload a drools.package file) to see your classes

7. Clicking a Guvnor repository business rule file in Eclipse throws a WebDav
error "not found", both for brl and gdsl files. Could it have to do with the
fact that the package doesn't validate at the moment?

Guided editors are no longer supported by eclipse plugin (brl was, gdst never was). Officialy due to a lack of interest from the users ... brl was very badly handled anyway, so may be it is better like this.
But you can still download it to your local drive, and edit it in XML (if you really want to).

8. Clicking in Eclipse in the Guvnor perspective a freshly created rule flow
(nothing uploaded yet) throws an exception as well...

How can you have a "not uploaded yet" resource in the Guvnor perspective (view rather that perspective I think) ?
