Hi,
I'm having a similar issue like you at the moment.
I set the growing attribute of my sap.m.Table to true, but I don't see the "More"-button at the end of the table which you mentioned.
I wondered if you found a solution to your problem and if you could share it with me?
EDIT: Ok so I just found out that the button is present, but it is not displayed (via CSS-Style "display:None").
I made it visible manually and now have the same problem as you, pressing the "More"-Button doesn't do anything.
Any idea how one could fix this?
Thanks in advance,
Felix
