Hi, I have created my own class. In a document, I'm able to create a object of that class, write and read fields in that object, but I don't know how to memorize this object in the database: I was looking on the developer guide on xwiki.org and I found only this page http://www.xwiki.org/xwiki/bin/view/DevGuide/DatabaseTutorial (which is not complete, unfortunately for me). Can anyone help me, please? Vito

Thanks Vincent, I'll try it. If it is working, of course, I'm going to put some information on xwiki.org. Thanks once again! Vito Vincent Massol wrote:

hmm seems like the $xwiki.saveDocument() api is internal only. You should use the $mydocument.save() API instead. -Vincent

It doesn't seem to work: I still get a 0 from this function: $doc.getObjectNumbers("XWiki.ClassName")) Vincent Massol wrote:

I've never done it myself but maybe someone else here can help. You could also check if you find examples in the source code or in the pages of XE. -Vincent

This example - http://objectwebcon06.objectweb.org/xwiki/bin/view/XWiki/CFP?xpage=code&… #set($xwiki2 = $xwiki.xWiki) #set($context2 = $context.context) ## ID #set ($sql = "select max(prop.value) from BaseObject as obj, LongProperty as prop where obj.className='XWiki.CFPClass' and prop.name='id' and obj.id=prop.id.id") #set($id=1) #foreach ($item in $xwiki.search($sql)) #set($id=$item.intValue() + 1) #end #set($newdoc = $xwiki2.getDocument("CFP.No${id}", $context2)) $xwiki2.saveDocument($newdoc, $context2) I'm not sure exactly what you were attempting to do but maybe this trick of getting the internal xWiki and context and using them for saveDocument can help you. My use case also requires doing fancy things with objects so please help out the documentation if you are successful! David On 10/18/07, Vitantonio Messa <vitantonio.messa(a)coss.fi> wrote:

Checking the code it seems that this would be similar to $newdoc.save (). Not sure why that's not working. Getting the internal object has 2 issues: 1) It requires programming rights so if this page is edited and saved by someone without programming rights it'll fail 2) we are planning to completely modify the internal implementation in the near future of xwiki so it shouldn't be used as much as possible. If APIs are missing in the public API then we should add it there instead. Thanks -Vincent

Hi all, here is the piece of code used to store a new object: ## Create a new object for this user #set($attendee = $doc.newObject("XWiki.AttendeeClass")) $attendee.set("name",$usr) $attendee.set("answer","yes") ## Add a new object to the page # $doc.save() Of course the "XWiki.AttendeeClass" class was created before. It wasn't working at the first attempts because I was trying to create the object with the function $Class.newObject(), I have no idea why, but changing the creation of the object in $Document.newObject() makes everything work fine. Hopefully today (in my spare time) I'm going to write this information in the www.xwiki.org. Vito Vincent Massol wrote:

Hi once again, as I said, I'm using $doc.save() to add objects to the page. Everything works fine until I log-in with an user that have writing rights, but I get error if the user doesn't have writing rights: Invocation of method 'save' in class com.xpn.xwiki.api.Document threw exception com.xpn.xwiki.XWikiException: Error number 9001 in 9: Access denied in edit mode on document... Is there a way to let users with no writing rights to call $doc.save()? Vito Vitantonio Messa wrote:
