Confused event receivers

Posted on 2014-01-27

I've written and deployed a feature. This feature has 3 event receivers.
Each event receiver is tied to its own list using <Receivers ListUrl="Lists/Registrations"> in its respective Elements.xml file.

When I go through and test the receivers they all work as expected except they will often given the returned message (properties.ErrorMessage) of one of the other event receivers!
Could this be a caching issue?
Also, when I attempt to delete a shared document I get the message that only site admins can delete the document (which is how one of the event receivers works on a different list)... none of the 3 event receivers have anything to do with the shared documents library!

The 3 event receivers are tied to the follwing 3 custom lists
<Receivers ListUrl="Lists/Registrations">
<Receivers ListUrl="Lists/PastRegistrations">
<Receivers ListUrl="Lists/Courses">

They are all bound to the ItemDeleting event.
Any ideas?

Hi,
which SharePoint version and edition?
How does your environment look alike (no of WFE, App ...)
Could you use Powershell or SharePoint Manager (from codeplex) to get the list associated event receivers?
Could you post your complete feature def XML as well as infos about your coded event receiver (the same for all three or dedicated for each list ...)
Thanks and HTH

Sharepoint Server 2010
1 WFE, 1 app server, 1 DB server

I have sharepoint manager 2010 and can navigate through the sites/lists etc but am not sure what info to provide. When I go to the lists I don't see the names of the event receivers. Can you let me know what to provide?

<Feature xmlns="http://schemas.microsoft.com/sharepoint/" Scope="Site" Hidden="TRUE" Title="TrainingCourseUtilities" Id="520c6b04-bc00-47e6-871a-d9f10aa0d640">
  <ElementManifests>
    <ElementManifest Location="StopCourseDeletes\Elements.xml" />
    <ElementManifest Location="StopRegDeletes\Elements.xml" />
    <ElementManifest Location="StopPastRegDeletes\Elements.xml" />
  </ElementManifests>
</Feature>

This is the same for all three except for the ListUrl (which I have confirmed are all correct)

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <Receivers ListUrl="Lists/Courses">
      <Receiver>
        <Name>StopCourseDeletesItemDeleting</Name>
        <Type>ItemDeleting</Type>
        <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
        <Class>TrainingUtils.StopCourseDeletes.StopCourseDeletes</Class>
        <SequenceNumber>10000</SequenceNumber>
      </Receiver>
  </Receivers>
</Elements>


This code is the samefor all 3 too - just the errorMessage is different

public override void ItemDeleting(SPItemEventProperties properties)
        {
            base.ItemDeleting(properties);

            using (SPSite site = new SPSite(properties.WebUrl))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    int _currentUser = properties.CurrentUserId;
                    SPUser spCurrentUser = web.SiteUsers.GetByID(_currentUser);
                    if(spCurrentUser.IsSiteAdmin == true)
                    {
                        properties.Cancel = false;
                        properties.Status = SPEventReceiverStatus.Continue;
                    }
                    else
                    {
                        properties.Cancel = true;
                        properties.ErrorMessage = "Courses can only be deleted by a site administration";
                    }

                }
            }

Hold the front page, I am reading where others have had the same issue.
It seems that if the feature is scoped to the site level then the event receivers will be fired on all lists regardless. But if it is scoped to the web lvel then the Receivers ListUrl will be respected. I will change this, redploy and test and let you know.

Why couldn't this be mentioned in Technet/other???
