  • I still have the same issue in RC. Even though there is no error when you peform various operations on the site UI, but you may find this error in the system Event Log. Here is my resolustion:

    Go to <drive>:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\CONTROLTEMPLATES,
    Open TaxonomyPicker.ascx in any text editor,

    Locate the following line :
    <%@ Control className="TaxonomyPickerControl" Language="C#" Inherits="Microsoft.SharePoint.Portal.WebControls.TaxonomyPicker&#44;Microsoft.SharePoint.Portal, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

    Replace '&#44' with ',' , the correct line should look like

    <%@ Control className="TaxonomyPickerControl" Language="C#" Inherits="Microsoft.SharePoint.Portal.WebControls.TaxonomyPicker, Microsoft.SharePoint.Portal, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

  • While this appears to be a fix, it may not prevent the error from displaying since this TaxonomyPicker class does not exist in Microsoft.SharePoint.Portal.dll.  A better solution, IMO, would be to rename this TaxonomyPicker.ascx control since it is not used.  See Todd Carter's post for more information:  http://todd-carter.com/post/2010/05/03/Help-Wanted-Taxonomy-Picker.aspx

  • My observations

    Essentially, I believe it was replaced with TaxonomyTreePicker.aspx.

  • Hey Guys,

    I just hit this with the RTM release.  I've just used the &#44; -> , fix and left it at that.

    A shame it ended up in the RTM (I've seen a few things that were Beta/RC bugs and still in RTM), but I guess it was both low impact and late in finding solutions.

    Update: after fixing the @#44; I still have the problem, so I renamed the file, which fixes it. Until you run psconfig/SharePoint Config Wizard, which seems to put the file back again (I installed Web Apps to get FAST going)

    Later'ish

  • Hi!

    I have the same problem and after fixing the line the error still comes up time to time. Is this somehow linked to the users presence feature? I have faced a problem where users presence tags goes "offline" when their not supposed to...at the same time these errors come up. RTM! Now I renamed it and hoping that the errors would go away. SharePoint...what a pain in a butt...always something!

  • I changed the filename to TaxonomyPicker_broken.ascx, and it still shows the error in Event Viewer...and users presence tag still not showing...waited over night but no change.

    /_controltemplates/TaxonomyPicker_broken.ascx lataaminen epäonnistui: Could not load type 'Microsoft.SharePoint.Portal.WebControls.TaxonomyPicker' from assembly 'Microsoft.SharePoint.Portal, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c'.

  • I also continued to recieve this error after using the fix described above. I noticed later in the file that the &quot; string showed up several times on line 16. I believe this should be replaced with a '.

    Line 16:
    <a href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$PlaceHolderMain$ctl00$RptControls$onetidSaveItem&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, true))" onclick="return tunnelToTSMT();" id="editWithTermManagerLink">

    Replace with:
    <a href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions('ctl00$PlaceHolderMain$ctl00$RptControls$onetidSaveItem', '', true, '', '', false, true))" onclick="return tunnelToTSMT();" id="editWithTermManagerLink">

    This got rid of the error for me.

    Hope this helps.

  • Using reflector on Microsoft.Sharepoint.Portal and looking into Microsoft.Sharepoint.Portal.WebControls you won't find any TaxonomyPicker class!

  • Looks like Microsoft finally published an article on this:

    http://support.microsoft.com/kb/2481844

    Only problem is, they do the escape code mod. Which in my experience, doesn't always work. Particularly if you have to do a PSConfig at anystage, as the file seems to get regenerated...

    At least it's officially acknowledged now.

  • It appears that iliastsouk is correct. The TaxonomyPicker.ascx control does not seem to be used at all in SharePoint 2010.  It has been suggested that this control has been superseded TaxonomyTreePicker.aspx.  I would like to see some verification from the SharePoint product team on this.

    Therefore, it should be safe to rename the file to something like "TaxonomyPicker.ascx_broken" and forgetting about it.

    Wednesday, June 01, 2011 10:00 PM
  • the only thing you need to do is to remove TaxonomyPicker.ascx, it is not being used by sharepoint, I removed totally from my enviroment runnig in 5 servers, and I am not receiveing the error anymore, and I don't have any issue

    Wednesday, June 01, 2011 10:34 PM
  • Hey Mohammed,

    while renaming/deleteing the TaxonomyPicker.ascx file certainly does fix the problem, please be aware that next time you have to run PSCONFIG, the file will come back and so will the error.

    While this probably isn't a big deal for production environments, as you don't run PSCONFIG very often (only major patches/service packs should need it), can be a pain in test/dev.

    Note: while I haven't applied SP1 beta anywhere, I haven't seen anything in the (beta) documentation that suggests that this problem goes away with SP1. But the SP1 documentation (and the beta download) only included hotfixes from 2010, so MS may have addresses it since then.

    Later'ish

  • Thanks, this got rid of the error code 7043, now I'm getting an error code of 6857.  Im just trying to get email messages from my sharepoint designer workflow to show up in my outlook inbox.  Have already configured both servers so that my server that has sharepoint sends messages to my outlook account, and the outlook server to receive email from my sharepoint server.  This may be a firewall issue between the two servers??

  • Hi

    I've just used the "&#44;" to "," and then tested the solutions by creating some SiteCollection, every ting whent well until I accessed the new site on IE, regardless of using a remote client or the same Server the error was logged again. In my case the error was logged only when accessing for the first time the newly created SiteCollection.

    I gave a try to the “File Renaming” solution, then I renamed the file \14\TEMPLATE\CONTROLTEMPLATES\TaxonomyPicker.ascx, deleted the Site Collections I created previously and created some new ones, accessed the new site from IE and then, no more error. I still have to deal with one Warning regarding the “Object Cache: The super user account utilized by the cache is not configured…” but I wanted to share which solution worked for me.

    My environment is W2K8R2 and SP2010STD with SQL2K8R2.
