I am trying to pass the page context into the simpledatalist lookupinfo for a field in a listbuilder. I am able to hardcode a guid as the Value, but when I try to pass the same value from the page context I get an error saying to select a valid record. I am using the following syntax:
<OutputField Name="CAMPAIGNPRIORITYSUBPRIORITY" Caption="Campaign priority - subpriority" DataType="String">
<LookupInfo>
<SimpleDataList SimpleDataListID="e3e9e22a-85f2-4a77-ba74-25b391252dab" >
<c:Params>
<c:Param ID="CAMPAIGNID">
<c:Value>3f5dc520-f5f7-4c0c-892d-0fae6b81ede7</c:Value>
</c:Param>
</c:Params>
</SimpleDataList>
</LookupInfo>
</OutputField>
