[rules-users] Guvnor another few questions...

[Michael Anstis]

Thanks for your input Vincent.

I've added some more blurb to your reply ;)

> *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) ?
