I have issue on connecting LS server one multiple page

[rvkvino]

Could you please give me the code sample that creating an instance from lsClient. I have tried but showing lsClinet not having constructor method.

Hi rvkvino,

Basically, in every page you should have something like this

var lsClientPageX = new LightstreamerClient(protocolToUse+"//mydomain.com:"+portToUse,"SLNSTOCKLISTDEMO_REMOTE" );

lsClientPageX.enableSharing(new Lightstreamer.ConnectionSharing("CommonConnection" , "ATTACH", "CREATE"));

Hi,
I have tried this already, But what happens means if I give this connection to open all the page means It terminating the session and continuously trying to reconnect the session. While I navigate the tabs more than 3 times means it disconnect the session.

Hi rvkvino,

Any chance to collect the client log of one of the page?
You should add to your code something like this:

var loggerProvider = new SimpleLoggerProvider();<br /> LightstreamerClient.setLoggerProvider(loggerProvid er);<br /> <br /> var cats = ["lightstreamer.sharing","lightstreamer.stream","li ghtstreamer.protocol","lightstreamer.session","lig htstreamer.actions","lightstreamer.grids","lightst reamer.subscriptions"];<br /> for (var i=0; i<cats.length; i++) {<br /> var myAppender = new ConsoleAppender("DEBUG",cats[i]);<br /> loggerProvider.addLoggerAppender(myAppender);<br /> }

the log will appear in the browser console.

Hi,
I have tried this like below, It is working on my browser but not working on the device.
This file written in lsconnection.js and globally included in my application.
var protocolToUse = document.location.protocol != "file:" ? document.location.protocol : "http:";
var portToUse = document.location.protocol == "https:" ? "443" : "8080";
var lsClient = new Lightstreamer.LightstreamerClient(protocolToUse+"//mydomain.com:"+portToUse,"STOCKLIST_REMOTE");
lsClient.connectionOptions.setHttpExtraHeaders({"u sername" : "bullion"});
lsClient.enableSharing(new Lightstreamer.ConnectionSharing("CommonConnection" , "ATTACH", "CREATE"));
lsClient.connect();

And all of my three controllers written the code like bellow and subscribed in this controller only.
var protocolToUse = document.location.protocol != "file:" ? document.location.protocol : "http:";
var portToUse = document.location.protocol == "https:" ? "443" : "8080";
var lsClient = new Lightstreamer.LightstreamerClient(protocolToUse+"//mydomain.com:"+portToUse,"STOCKLIST_REMOTE");
lsClient.connectionOptions.setHttpExtraHeaders({"u sername" : "bullion"});
lsClient.enableSharing(new Lightstreamer.ConnectionSharing("CommonConnection" , "ATTACH", "CREATE"));
var liverateSubscription = new Lightstreamer.Subscription("COMMAND", liverateId, fieldList);

This working well without terminate the session on browser (ionic serve --lab). But not working after build the app and check in real device.

Hi rvkvino,

Please let me suggest some tests to be run:

1. Have you tried a very simple application with only one page and one subscription just to chek if is ok on a real device?
2. Could yuo tried your code without the lsClient.enableSharing(...) statement?

Regards,
Giuseppe

And also I have tried in this application without using lsClient.enableSharing in this case losing the session after navigate 3 times between connected LS Server page.

We are on fire, Client making urgent to fix this issue soon. could you please help me to fix this issue soon.
