can only pull a customfield value directly in tableview - need in field definition so I can filter!

[Nat Grauman]

Hey all, I have a tableview with a column where FieldName=JiraID.fields.customfield_38403 and it populates just fine in my table. I want to filter this field for a specific set, but when I enter this "field name" in the filter field, the page throws an error.  So, I've tried defining a field (EPICID) in my main form, and using SetValue in a Field Rule to say EPICID=[entry.JiraID.fields.customfield_38403], but in my tableview, the EPICID column doesn't populate at all.  I have other fields where I've done this and the value populates.  I looked at the JSON for customfield_38403 to see if I need to do FieldName=JiraID.fields.customfield_38403.some_attribute and there appear to be no attributes. 

UPDATE:  It seems that SetValue is working, but the only way to make it populate on my tableview is to click the edit button and "touch" the record by making some change in one of the confiforms fields, which seems to refresh the whole record. Then, one by one, the CustomField_38403 populates.   Does this make sense?  Is there anyway to get the entire set to refresh at once without having to do this one by one?
