NullReferenceException when using Content Query webpart with BCS List

Posted By:      Posted Date: October 16, 2010    Points: 0   Category :SharePoint



I have a BCS List in my SP 2010 solution, which works fine. Now I want to add the Content Query web part that sources its data from this external list. In the Content Query web part properties, when I select my External list in the "Show items from the following list" field, I get this exception:

[NullReferenceException: Object reference not set to an instance of an object.]
  Microsoft.SharePoint.Publishing.WebControls.ContentByQueryToolPart.OnPreRender(EventArgs e) +216
  System.Web.UI.Control.PreRenderRecursiveInternal() +107

  System.Web.UI.Control.PreRenderRecursiveInternal() +223
  System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3393

Is it even possible to do this? Or is there another way? Thanks in advance!

Problem with Content Query Webpart and Custom Userfields

Dear Community, I am using Sharepoint 2007's content query webpart to access content types from 2 lists each contained in a different sitecollection. To achieve this, I used this tutorial: http://www.heathersolomon.com/blog/articles/CustomItemStyle.aspx. The tutorial worked great. By using the property CommonViewFields and modifing the XML Stylesheets accordingly, i could access almost every field. Even User Fieldtypes like editor and author were accessible by adding (editor,User) or (author,User) to the CommonViewFields property. But when I tried to access the custom made userfield "Username" in the same way (adding Username,User to the property), the webpart threw an error and couldn't be displayed anymore. When I changed it to Username,Text , no error occured but it naturally didn't show up, since it is the wrong fieldtype. I hope some of you can help me, since all my researches on this topic only brought up some more people with the same problem, but no solution to it. Thanks in advance, SoundofSilence

Content Query Webpart Missing Content Type and Approval Status


I'm a great fan o the CQWP , and love the changes made in 2010 on this webpart. What bothers me is that I use to Filter Documents by Approval Status, thus showing Draft or Pending Documents and Group these by their Content Type.

Both these were available in 2007, but removed from 2010 CQWP. Any idea why, or how to bring this back? sample or URL guidance would be great. My gut feeling is custom XSLT but id like to confirm this first.

Thx a lot

Content query webpart - presence icon not getting displayed



The ContentQueryMain.xsl has a template "CallPresenceStatusIconTemplate" for displaying the presence icon (Microsoft communicator presence) which is called from the ItemStyle.xsl template. The ContentQueryMain displays it based on the SipAddress. Though the SipAddress is updated in user profile store, presence icon is not getting displayed. Sip format is "sip:domain\username"

I tried printing all the fields that are available to CQWP using the below code

<xsl:for-each select="@*">
    P:<xsl:value-of select="name()" />

But in the field list I don't see SipAddress. I tried adding a site column SipAddress to the list that I'm binding, even then it doesn't get displayed in the field list.

Any suggestion is appreciated



Content Query WebPart shows page items with status "draft", and page items that current user does no



I have this issue that CQWP is rendring items that it should not render. I test this with a read-only user, that should NOT see draft pages or pages with different permissions. But the read-only user do see the items, but when I click on the link I get access denied. This access denied is correct, but why does the page items appear in the CQWP at all?


1) I use OOTB CQWP (inherits from ContentByQueryWebPart in my .webpart file) : "<type name="Microsoft.SharePoint.Publishing.WebControls.ContentByQueryWebPart ....." and I have my custom xsl to get the look and feel I need

2) The issue with page items showing when status = drafts only appear when using the PublishingExpirationDate field. When I try creating new pages and give them status draft by using "check in to share draft" (logged on as an contributer/approver user), this item wil NOT appear in the CQWP for the read-only user. When I change a pages' status from approved to draft, this item will still be shown in the CQWP, but this will point correctly to the published version. But after the pages' expired date (PublishingExpirationDate) is expired, the page gets status "draft" (handeled by a timer job I guess), and this page item will still be rendered in the CQWP, but sending the read-only user to an access-

Editing the list and view of a content query web part

Error "List does not exist" trying to insert pictures or links from Content Editor WebPart


I have put a Content Editor WebPart on a page and I'm trying to insert a picture from the Rich text editor, but whenever I try this I get this error:

List does not exist.

The page you selected contains a list that does not exist. It may have been deleted by another user.

This also happens when inserting links. When I use Fiddler I can see that the error occurs somewhere in AssetPortalBrowser.aspx and It's likely that the last location used to insert pictures and links no longer exist. So the question is how do I reset the location to point to a list on the current site, or any other list for that matter? I tried deleting and adding the WebPart on the page without any luck. Typing in a valid link in the link text box or setting the attribute "DefaultToLastUsedLocation" to "false" in the call to AssetPortalBrowser.aspx did not work either. I read the solution at http://mossipqueen.wordpress.com/2008/08/08/assetportalbrowser-error-list-does-not-exist/ (de- and re-activate Office SharePoint Server Publishing feature) but the feature is not activated on my web. Does anyone have a tip on what to do? This happens on a live SharePoint environment so there may be some restrictions as to what I can

Strange behaviour taxonomy filter in content query webpart on anonymous website


We are experiencing strange behaviour on a publishing facing website implemented in SharePoint 2010.

The story
We use a (default) Content Query Webpart to show related information in relation with the current page. The filter is using a field value (UserFieldValue) of the current page and filters other pages which have the same tags. The fields, on the current page and the related pages, are taxonomy field. Everything works fine!

We published the pages, looked at the website as an anonymous user and everything was still going smoothly. We went home, slepts an hour of 6, waked up. Proudly checked our beatifull new website :). Ahhhhh, what is this.. all content query webpart with the filters on the taxonomy field returned exactly nil.

We logged in to our website, checked if the pages where published, and well, they are... Just published them again. And everything looked fine again.... but not for long. Exactly the next day (... app pool recycle ...) the same problem ...

Logged in again to our website, logged out...  problem solved.... till the next apppool recycle.

My conclusion
Until the firrst authenticated visit to the page the taxonomy filter on the content query webpart silenty fails.

As a "temporary" workarround we have created a sc

Content Query result without link to source list

I've added a content query webpart to a page to show a multiple line text field from a list item. That works fine but the content is shown as hyperlink and if I click the content, the source item of the list is shown. I wanted to use the content query only to show the filtered content, without having the possibility to open the related item. Is that possible or is the content query webpart the wrong way to show content from different sources (lists) only as text in a page?
