[xwiki-devs] Some questions about the XWiki API...

[Fabio Mancinelli]

Hi everybody,

I am finishing the XMLRPC interface but I am stuck on some points... I  
still haven't found the way to do this so I am asking here to the API  
gurus that surely have the solutions I am looking for:

1) I don't know how to retrieve the list of language IDs that are  
configured in the "xwiki/bin/admin/XWiki/XWikiPreferences" in the  
Parameters/Languages field. I would need this for knowing what are the  
"available" languages in a XWiki instance.

2) I cannot understand how to create a new "translated document".  
Currently I do

    Document doc = xwiki.getDocument(pageId);
    doc = doc.getTranslatedDocument(language);

Now, if a translation for the given language is not *already*  
available, getTranslatedDocument returns the same document returned by  
getDocument (i.e., the default translation). But here I would like to  
"create" the new translated document that does not yet exist.  
Basically I am looking for something semantically equivalent to  
getDocument that creates a page if it doesn't already exist.

3) Removing an attachment seems impossible without switching from the  
API to the low-level functions. In order to remove an attachment I  
tried to do this:

Document doc = xwiki.getDocument(pageId);
Attachment xwikiAttachment = doc.getAttachment(fileName);
doc.getDocument().deleteAttachment(xwikiAttachment.getAttachment(),  
xWikiContext);

but xwikiAttachment.getAttachment() returns null, and this happens  
when the hasProgrammingRights() check fails. The same user is able to  
delete attachments via web, but I cannot understand how to mimic the  
same functionality by having the API as the entry point.

Sorry if these are trivial questions but, as I said before, I am stuck  
and looping :)

Thanks.

Cheers,
Fabio
