Code Activities being skipped after AddToCollection<T> in WF 4.0
===

I can't figure out where my program flow is going in my WF 4 application. I have a Flow chart with a series of an AddToCollection and two code activities. When I step through, it hits the AddToCollection breakpoint and then just continues, skipping my code activities as if they weren't even there. I have no idea where to look because I am very new to WF 4. 

Here is a XAML snippet if it helps:

    <AddToCollection x:TypeArguments="x:String" Collection="[EmailList]" DisplayName="AddToCollection&lt;String&gt;" sap:VirtualizedContainerService.HintSize="200,22" Item="abc@blah.com" />
      <FlowStep.Next>
        <FlowStep x:Name="__ReferenceID0">
          <sap:WorkflowViewStateService.ViewState>
            <scg3:Dictionary x:TypeArguments="x:String, x:Object">
              <av:Point x:Key="ShapeLocation">400,180</av:Point>
              <av:Size x:Key="ShapeSize">200,22</av:Size>
              <av:PointCollection x:Key="ConnectorLocation">500,202 500,232 500,240</av:PointCollection>
            </scg3:Dictionary>
          </sap:WorkflowViewStateService.ViewState>
          <local:CompileEmailBody EmailBody="{x:Null}" EmailList="[EmailList]" sap:VirtualizedContainerService.HintSize="200,22" Products="[Products]" SwProduct="[SwProduct]" Type="Request" />
          <FlowStep.Next>
            <FlowStep x:Name="__ReferenceID1">
              <sap:WorkflowViewStateService.ViewState>
                <scg3:Dictionary x:TypeArguments="x:String, x:Object">
                  <av:Point x:Key="ShapeLocation">400,240</av:Point>
                  <av:Size x:Key="ShapeSize">200,22</av:Size>
                </scg3:Dictionary>
              </sap:WorkflowViewStateService.ViewState>
              <local:SendEmail Message="{x:Null}" Body="[EmailBody]" EmailList="[EmailList]" sap:VirtualizedContainerService.HintSize="200,22" />
            </FlowStep>
          </FlowStep.Next>
        </FlowStep>

Anything helps, I have no idea where to start!
Cheers
