Dear Boppana,

A first problem i noticed is the order you discribed in your mail:

> I have used reader client and configured it to capture events
> Started Event Sink
> Added a new tag to Shelf 1
> But this event is not shown in Event Sink

The reader establishes a connection to the sink when the command to create
a notification channel is sent. If you configured the reader and started
the event sink afterwards, no connection is established for the
notification channel. When you close the reader and a connection was
established, a message should appear in the EventSinkUI that sais 'ERROR:
connection reset'. If this message does not appear, there was no
connection and thus no notifications were able to reach the EventSinkUI.

A potential second problem i noticed in your mail is the usage of non
default DataSelector. The DataSelector was buggy and is still buggy in the
latest release. I fixed it in the current developer version last week. For
further testing of accada, please leave away the DataSelector
configuration (steps 4 to 7 in your list of configuration commands below)
until next release of a new accada version.

Kind regards,
Jonas
