Hi,

 

I have following error in event logs:

TF53010: The following error has occurred in a Team Foundation component or extension: Date (UTC): 7/5/2012 12:13:13 PM Machine: ENTI0005 Application Domain: /LM/W3SVC/8080/ROOT/tfs-5-129859636484095160 Assembly: Microsoft.TeamFoundation.Framework.Server, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a; v2.0.50727 Service Host: 6e95ec4d-64f3-43d9-9072-b596326051af (Data Integration Services) Process Details: Process Name: w3wp Process Id: 3480 Thread Id: 6456 Account name: EAIMP\XBBJ6FR Detailed Message: An unexpected error has occurred.

and here is my TeamAlert config:

<!--?xml version="1.0" encoding="utf-8"?-->
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="teamAlert" type="Dymetis.TeamAlert.Configuration.TeamAlertConfigurationSection, Dymetis.TeamAlert" />
  </configSections>
  <teamAlert>
    <alerts>
      <alert name="Notify new user on change AssignedTo" event="WorkItemChangedEvent" filterExpression="$&quot;CoreFields/StringFields/Field[ReferenceName='System.AssignedTo']/NewValue&quot; &lt;&gt; $&quot;CoreFields/StringFields/Field[ReferenceName='System.AssignedTo']/OldValue&quot; ">
        <recipients>
          <recipient name="NextAssignedTo" address="CoreFields/StringFields/Field[ReferenceName='System.AssignedTo']/NewValue" type="DisplayNameField" allowHtml="true" />
        </recipients>
      </alert>
    </alerts>
  </teamAlert>
</configuration>

Could you please advice what is wrong?
