Indeed. You can create blog titles as long as you wish them to be, but the best is to avoid any character outside aA - zZ & 0 - 9.

If you use spaces in your titles they will generate URLs such as xwiki/bin/view/Blog/My+New+Blog+Article. The best way to keep URLs clean is to ask your users to write MyNewBlogArticle as their title, and then change it to something nicer.

One thing I find weird is that usually a js function is called to clean the name of a page before the page is created to help prevent such problems as the one you encountered... Can you check whether new blog posts name go through the xwiki updateName() jc function ? Your life would get much easier if they did, as in :

<form action="" id="newblogarticle" method="post">

<input type="hidden" name="template" value="Blog.ArticleClassTemplate"/>

<input type="hidden" name="sheet" value="1"/>

Article Name : <input type="text" size="40" name="articlename" value="Your blog article"/>


#NOTE HOW updateName() IS USED BELOW

<input type="button" value="Add this blog article" onclick='if (updateName(this.form.articlename)) {this.form.action="../../inline/" + this.form.space.value + "/" + this.form.articlename.value; this.form.submit(); }'/>

</form>


Hope this helps,

Thanks, Guillaume - it worked!!

 

Obviously the special characters have been the problem. So, am I correctly understanding that string length doesn't matter and spaces are OK, but special characters shouldn't be used? Since I have to instruct the future users of the blog...

 

Thanks again for the help,

Darina

Hi,

 

have you tried entering the same title but removing out special characters such as "," and ":" ? They might be the cause of your problem.

 

-> you may want to prefer using "IdentityHowToNameItHowToFindIt" to create new pages (because that's what will show up in the URL) and then use nice name and special chars only in the title field of your blog post once on the blog article page...

Hello,

I have installed a virtual wiki (using XWiki 1.2, MySql, Tomcat 5.5.17),
with a blog with editing rights given to only a specific user group.
Sometimes (but not always) there is a problem in creating new blog
entries (the error doesn't occur each time and it occurs also if the
admin creates the entry ...):

The latest: when trying to enter an article with posttitle "Identity:
How to Name It, How to Find It" I am getting the error:

Error number 4001 in 4: Error while parsing velocity page Wrapped
Exception: Invocation of method 'getDocument' in class
com.xpn.xwiki.api.XWiki threw exception
java.lang.StringIndexOutOfBoundsException: String index out of range:
-10 @ [47,21]

The stack trace is bellow.

I have entered before articles with longer titles - is there a
restriction for the length? Any idea what could be the reason for this
error?

Thanks,
Darina
