MetaDataAdapter filtering using isSelected()

pwestlake

I would like to filter events based on client criteria. I have implemented a MetaDataAdapter as described in http://www.lightstreamer.com/vb/showthread.php?t=65&highlight=isSelected

This works. However there is only one MetaDataAdapter per lightstreamer adapter. So the same filter criteria is used for each client that has subscribed. I am new to lightstreamer so I think I am missing something, but how do I configure this so that for example: client 1 only receives events for changes to account 1 and client 2 only receives events for changes to account 2?

The isSelected() method of the MetaDataAdapter has a user parameter, but this is always null!

Thanks,

Phil

to get a value on the user parameter of the isSelected method you have to set a user name (and a password if needed) on the client side. In example, if you're using the javascript client you can call the setUserNamemethod of the Connection instance of your LightstreamerEngineinstance obtained through the onEngineCreation callback:
[syntax="JS"]var lsPage = new PushPage();
[...]
lsPage.onEngineCreation = function(lsEngine) {
lsEngine.connection.setUserName("userName");
[...]
};[/syntax]

Btw note that maybe in your case it could be better if you use two different items instead of using a single item to be filtered.

My issue was actually fixed by resolving a threading issue in my code.
