Header name in tableview

Hi,

I build a custom activity that returns some data as a featureset. The data comes from an external database and is not available as a mapservice. To show this data as a table to the user, I use SelectFeatures (with only the FeatureSet parameter), and then 'OpenDataFrame' and 'SwitchToWideView'.

This works, but because the data is not linked to a layer, the table has no header, only a globe icon. Setting the Collection Name or Layer Name on the SelectFeatures task makes no difference:

/customer/servlet/servlet.FileDownload?file=00P6000000elzGyEAI

Is there a way to still set a header?
