Netui-data:getData no populating pageContext attribute in portlet

Question

I am attempting to create several pageContext attributes in a page flow and I'm having issues. When I test the page flow itself it works like a charm. But when I generate a portlet based on the same page flow netui-data does not populate the pageContext attribute.
My code is pasted below. Any help would be greatly appreciated, pulling my hair out.
<%@ page language="java" contentType="image/gif"%>
<%@ taglib uri="netui-tags-databinding.tld" prefix="netui-data"%>
<%@ taglib uri="netui-tags-html.tld" prefix="netui"%>
<%@ taglib uri="netui-tags-template.tld" prefix="netui-template"%>
<netui-data:getData resultId="imageByteArray" value="{pageFlow.img.TnImage}"/>
<netui-data:getData resultId="mimeType" value="{pageFlow.img.TnMimeType}"/>
<%
Enumeration e1 = pageContext.getAttributeNamesInScope(1);
while (e1.hasMoreElements())
System.out.println("pageContext attributtes: " + e1.nextElement().toString());
request.setAttribute("byArr", pageContext.getAttribute("imageByteArray"));
request.setAttribute("mimeType", pageContext.getAttribute("mimeType"));
request.setAttribute("tiny", "tim");
Enumeration e = request.getAttributeNames();
while (e.hasMoreElements())
System.out.println("request attributtes: " + e.nextElement().toString());
%>
<jsp:forward page="/showImage" />

Personally, I have had a hard time doing what you are asking for using netui tags. I have had the same case, and asked the person in my team to just return a collection of value objects and then iterate through it without the repeater tag. To use the checkbox, I have had to use a String[].
