both calls to setDebugAlertsOnClientError() are set to true.

At the moment yes all that happens is the 'Lightstreamer is connecting...' msg. Nothing further.

I've double checked the port/hostname/domain settings, all fine. I can get the simple OverwriteTable demo working with the StockList adapter so whatever it is it's specific to the client config for the Portfolio DynaMetapushTable?
