[xwiki-users] some questions concerning editing pages - more specific section behaviour - XWiki 1.8M1

Hi guys, I have some points that I don't understand in XWiki, which occur somehow like bugs to me. I just edited the WebHome article of the Main Space which came with the default XWiki-Xar-File. In that WebHome there are 2 sections defined, the first one being the started by a Title1 format caption and the second one being started by a Title2 format caption. First thing is, how can I get another section with Title2 format in that page. I couldn't find any documentation on this. When editing the page in XWiki1.0 syntax I tried to add a section by having a "1.2" prefix after the existing "1" and "1.1" section, but that results in 1.2 being printed on the resulting page instead of a Title2 headline and a new section. When I format Title2 using WYSIWYG, I get HTML syntax in Wiki-Syntax instead of 1.2 (which didn't work before). The result is, that the page has a new bold Title2 headline, but still no new section (besides the syntax being strange - HTML). Another point is, that I just reedited that page and now, after saving, the first section, the one with the Title1 headline is no longer editable. WebHome points to section 2 directly, though I still see the content in the page. Last point is: How can I get XWiki2.0 Syntax working? I enabled it in xwiki.cfg, but that doesn't seem to have any effect. I really hope, you can give me some hints on my troubles. BTW, I'm using MSSQL 2000, if that could be involved in the problems. Many thanx in advance. Cheers, Sebastian
