Subject [jira] Created: (JSPWIKI-252) Rename page with attachment kills Main-Page
Date Tue, 22 Apr 2008 13:48:23 GMT
Rename page with attachment kills Main-Page
-------------------------------------------

                 Key: JSPWIKI-252
                 URL: https://issues.apache.org/jira/browse/JSPWIKI-252
             Project: JSPWiki
          Issue Type: Bug
          Components: Core & storage
    Affects Versions: 2.6.2
         Environment: Java 1.6, JspWiki 2.6.2
            Reporter: akakunin
            Priority: Blocker


We met this bug in our www.emforge.org (it is used WikiEngine with own JSF GUI) - but I just
reproduced this problem in sandbox:
1. Create any Page (for example TestPage1)
2. Add attachment to this page (for example somefile.jpg)
3. Add text on this page referenced to this attachment: ( for example just [somefile.jpg])
4. So - now everything is ok - you have page with attachment and this page has link to the
attachment
5. Open page Info dialog and rename page (for example to TestPage2)
6. Everything is ok - page is renamed
7. Open Main-Page
8 - Uuups - Main page is Empty! (Right now you can check it in sandbox - I crealed main page
by this way)


I debug it a little bit - problem is in PageRenamer.updateReffererOrRename method. During
rename it is called with oldName=TestPage1 and newName TestPage2
At  line 238 it is created tempCtx for old page (TestPage1). Since (seems) this page is not
already exists - m_wikiEngine.getPage() returned null.
But WikiContext constructor for null page created context for Main page - and later - it is
cleared Main page.


In EmForge this problem is reproduced then we trying to report bug (via New Bug Wizard) and
has attachment (for example picture) and reference to attachment in bug-description (quite
common problem). So, since it is caused quite often - it is produced big problem for us -
so, it is why I marked this bug as blocker.

In any case - I do not think it is good that it is possible to clear Main page then you do
not do it :)

Please - feel free to contact me if you will need any additional info.
