Site Blog Dashlet for Alfresco Share

Updated December 2010: Site Blog Dashlet is now hosted on Share Extras.



This extension to Alfresco Share provides a custom Site Dashlet, which displays the most recent ten posts from the site blog component.



[caption id='attachment_134' align='alignnone' width='300' caption='Site Blog Dashlet']Site Blog Dashlet[/caption]



To install the dashlet download the ZIP file package the latest blog-dashlet.jar file from the Share Extras project and extract the contents into the tomcat directory of your Alfresco installation drop it into tomcat/shared/lib or WEB-INF/lib inside the Share webapp. The package will install the dashlet web script and a single CSS file.



Also pictured in the screenshot is the Site Tags Dashlet, which displays a tag cloud visualisation for all the tags within a site.

This is exactly what I've been looking for! I've tried this dashlet, however I get the following error as soon as there is at least one entry. Any ideas? :-(

Okay, the error only occurs when the Blog entry is shorter than 100 characters.



It's because of this line in site-blog.get.html.ftl:



${(post.content!'')?substring(0, 100)} ...

Goldmar, I've now updated the dashlet to fix this issue and several others. The updated dashlet can now be found here: http://code.google.com/p/share-extras/

Cool, this is great! I'll try it out! Smiley Happy

Hello!



Try adding a post with more then three doublequotes in it, in the first 100 chars.

It will break the dashboard for IE users.



Added ?replace(']+(>|$)', '', 'r') to the string, which helped.

<#if (post.content)?length${(post.content!'')?replace(']+(>|$)', '', 'r')}${(post.content!'')?substring(0, 200)?replace(']+(>|$)', '', 'r')} ...

Hi Henrik, are you using the version that's posted on the blog or the later version that's now part of Share Extras (http://code.google.com/p/share-extras/ )? If the latter, could you file a bug on the issue tracker there?
