Hi Dave,
You should read
http://platform.xwiki.org/xwiki/bin/view/DevGuide/Architecture , but I
understand that it might be cryptic for a first time usage so here we go:
must know that xwiki is a java engine, so there is some java code that
does things, it's not all done in velocity.
Basically, there is a java "platform" that can handle documents, objects
in documents, classes, etc (load, save) and then there is the velocity
scripting that you can do in wiki pages which **uses** this core
(injected variables like $xwiki, $doc). See here about how this
scripting in pages works:
http://platform.xwiki.org/xwiki/bin/view/DevGuide/Scripting .
Also, there are some interesting information about the data model here
http://platform.xwiki.org/xwiki/bin/view/DevGuide/DataModel .
The 'platform' project on git contains all this 'platform' code: java
sources, default templates, default js, css, etc, which you can enhance
in wiki pages (but we don't do everything in wiki pages, so you should
not look for it only in wiki pages).
Also, there are a bunch of "default" velocity templates that handle the
default layout and actions for the wiki (in the webapps/xwiki/templates
folder of the installation). For example, the save and view button is
generated by these templates, along with the url to which the data in
the form is posted.
I recommend firebug and LiveHttpheaders extensions of firefox to study
what data is posted to which URL, etc what data is received. from then
on, with the help of
http://platform.xwiki.org/xwiki/bin/view/DevGuide/Architecture#HUnderstandinghowHTTPrequestsarehandled
, you should be able to find the code that actually does the save.
Have fun,
Anca

Also from the following BlogPostSheet wiki code, after users type in
message from the inline form, users click Save& View button, how are the
messages saved to database?
see the attached code:
{{include document="Blog.BlogCode"/}}
{{include document="Blog.CategoriesCode"/}}
{{velocity filter="none"}}
{{html clean="false" wiki="true"}}
$xwiki.jsx.use('Blog.ManageCategories', {'mode' : 'select'})##

## Keep testing the inline action for backward compatibility with older
blog posts.
#elseif($xcontext.action != 'edit'&& $xcontext.action != 'inline')
## View mode
#isPublished($entryObj $isPublished)
#isHidden($entryObj $isHidden)
## displayBlog requires a list of documents, and whether to display only
an extract or the full entry.
#displayBlog([$tdoc] 'single' false false)

[${hideArticle}]))
#end
#else
#set($defaultDate =

#if($entryObj.getProperty('publishDate').value.time == $defaultDate)
## The publish date was not set, force it to be the creation date
$entryObj.set('publishDate', $doc.creationDate)
#end
#publishMessageBox("$msg.get('xe.blog.sheet.notpublished')

Hi, all
I am studying the BlogClass, BlogPostClass, I checked the Blog.BlogCode,
there are alot of velocity scripts, I can see the search documents from db,
but could not find any code related to insert document records into
database, so how is the document created from blog saved into database?
please point me to the script code in the Blog.BlogCode.
Thanks
Dave
