XML Viewer web part and SharePoint list RSS feed doesn't work

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :SharePoint
Hello, When I want to use the XML Viewer web part and set the XML URL to an RSS feed from a SharePoint list I get this error: Cannot retrieve the URL specified in the XML Link property. For more assistance, contact your site administrator. The URL I'm trying looks like this: http://sp2010/_layouts/listfeed.aspx?List=%7B76FD9EEE%2D9354%2D444E%2DBE3C%2DA9AE2C4B2063%7D I've seen blogpost that discuss this and they say that this is because of a security issue and that I have to enable anonymous access in order to display the RSS feed. Is this the only option there is ? I don't want to enable anonymous access on my SharePoint site. Why can't SharePoint just request the RSS feed with the credentials of the logged in user ? Or am I missing something here?

Workflow doesn't work anymore after renaming list

Hi All, I have created a list with the name "helpdesk test". After testing this list i renamed the list to "helpdesk". I did the rename by the list settings.  To this list i attached some workflows, with Sharepoint designer,  that have to start when a new item is created. All worked fine but after the rename the workflows don't work anymore. When i start the workflows manually from the list all works fine. Is there a way to rename a list and let the workflows work as before? Thanks in advance. Laurens.

SharePoint 2010 Chart Web Part does not appear to work

Using the sharepoint chart web part does not appear to work. Plotting a pie chart from a list with 10 items in it.  Using a numeric field for a Y axis and a choice field for X axis. The choice field has 4 possible selections. Clearly I want a pue chart with 4 slices. What I get is a pie chart with 10 slices, not much use. Fine I thought we've got this optional 'Group by field' so I'll group by my choice field. But then I get a pie chart with one slice?! Am I being dumb or does the chart web part not work properly?

Custom Web Part doesn't work with in anonymous access

Hi there, I have a custom webpart in a farm solution deployed to my site. Anonymous users should be able to view the site, however they can't because they are required to login due to the custom web part. If i remove the webpart from the page, anonymous users can view the site perfectly without the need to login. There is nothing really special about the webpart. It's a visual web part which uses the site and it's web data to display a sort of menu. Any idea? Thx in advance! Brecht
