[7.0.0-M1] Actions not setting parameters with Multi-part forms

The biggest issue I'm having at the moment is with all of my multi-part 
forms that include parameter data and a file. The action does receive 
the file, but the parameter "team.company" is set to the String value of 
stream, for example:
"org.apache.commons.fileupload2.core.MultipartInput$ItemInputStream@1afaa502" 
  Am I missing something obvious?

To add, it actually doesn't matter if I have a file field in the form.  
Any form with [enctype="multipart/form-data"] never sets the action 
fields properly.  Is there a different parser I should be referencing?  
Or are my interceptors not correct?


Example Form
<s:form name="frmTeamInfo" action="AdminTeam_update"
         method="post" enctype="multipart/form-data" 
accept-charset="utf-8">
     <s:textfield name="team.company" />
     <s:file id="logoFileUpload" name="upload"/>
     <s:submit value="Save" />
</s:form>

Parser
<constant name="struts.multipart.parser" value="jakarta-stream" />
