Update 5

Right I have carried on googling and cannot find a solution to this, I am however pretty confident that the collective mind of SO can. I am also convinced seeing the number of posts on various forums around the web that I am not the only person that has this issue.

So I am going to put this up for bounty as soon as I am aloud as I feel that the solution to this can benefit the sharepoint community.

Update 4

A bit more googling has yeilded the fact that there is indeed a "feature" in sharepoint 2010 xslt list view webpart in that an anon user cannot set the xsl or xsllink property.

This has now brought me back full circle in that I need to provide a styled list view to users and also a traditional allItems.aspx view to editors where they can update the content of their list any suggestions greatly welcome as I am running out of ideas on this one :-S

Thanks

Nicholas

UPDATE:

UPDATE 2

Could this be what the webpart is complaining about? and if so how can i give the webpart access to the xslt?

Update 3

I have tried using mapped folders to provision my XSL

and I can view the XSL through the browser ie browsing to the mapped folder.

<XslLink>/_layouts/xsl/newsportal.xsl</XslLink>

but the webpart generates this error in the browser

I have done a bit of reading around and found that webpart security has been enhanced in sharepoint 2010 and have found the following link which are suggesting that the way forward is to edit the web.config.

however I struggle to believe this is the truly the case that I need to lower the security levels to just set a predefined property of the webpart (XslLink) can someone please confirm or deny that this is the case.
