Custom Connection Message

rakeshxp

Hi,

Is it possible to inject code to have a UI similar to gmail gtalk ( or yahoo mail chat ) which can show "Connecting to chat server" and then if not present "not available" ?

Right now, is the server is not avaliable, it throws up a prompt every X secs. It would be great if we have the flexiblity of handling such cases so that so we have custom error messages and their formatting

I think I hit the enter too quickly :Smile_Ae:

I am talking about LS + dojo integration ( and the wierd dialog prompts when the LS server is not available )

Hi,

The Dojo demo should not show "not connected" prompts but (if you're running it from LS internal web server) it could show debug messages.

In any case your desidered behavior is feasible.

Please take a look to these API:
http://www.lightstreamer.com/docs/client_web_jsdoc/LightstreamerEngine.html#onStatusChange
http://www.lightstreamer.com/docs/client_web_jsdoc/Context.html#setDebugAlertsOnClientError

And to these threads:
http://www.lightstreamer.com/vb/showthread.php?t=68

Hope that helps.

Mone, Thanks a lot!!!
This is exactly I was looking for :Smile_Ab:

Please find the attached snippet and let me know if I have properly understood the api
var lsPage = new PushPage();
var e;
lsPage.context.setDebugAlertsOnClientError(false);
lsPage.context.setRemoteAlertsOnClientError(false);
lsPage.context.setDomain(domain);

lsPage.onEngineReady = function(engineRef) {
dojo.debug("Lightstreamer onEngineReady" ) ;
e = engineRef ;
engineRef.context.setDebugAlertsOnClientError(false);
engineRef.context.setRemoteAlertsOnClientError(false);
engineRef.connection.setUserName("cookie");
engineRef.connection.setPassword("password");
engineRef.connection.setLSHost(host);
engineRef.connection.setLSPort(port);
engineRef.connection.setAdapterName("XYZ");
engineRef.changeStatus("STREAMING");

e.onClientAlert = function ( code, message ) {
dojo.debug("WOW!!!! LightstreamerEngine onClientAlert code[" + code +"] message[" + message + "]" ) ;
}
e.onClientError = function ( message ) {
dojo.debug("WOW!!!! LightstreamerEngine onClientError message[" + message + "]" ) ;
}
e.onServerError = function ( code, message ) {
dojo.debug("WOW!!!! LightstreamerEngine onServerError code[" + code +"] message[" + message + "]" ) ;
}
e.onStatusChange = function ( chngStatus ) {
dojo.debug("WOW!!!! LightstreamerEngine onStatusChange status[" + chngStatus + "]" ) ;
}
}

lsPage.onEngineLost = function() { e = null; }

lsPage.onClientAlert = function ( code, message ) {
dojo.debug("WOW!!!! PushPage onClientAlert code[" + code +"] message[" + message + "]" ) ;
}
lsPage.onClientError = function ( message ) {
dojo.debug("WOW!!!! PushPage onClientError message[" + message + "]" ) ;
}
lsPage.onServerDeny = function ( message ) {
dojo.debug("WOW!!!! PushPage onServerDeny message[" + message + "]" ) ;
}
lsPage.bind();
lsPage.loadEngineMinimal("../struts/lightstreamer-client/lsengine.html");

Thanks,
Rakesh

Yes, it's ok :Smile_Ag:

Just move from the deprecated loadEngineMinimal to the newer createEngine:
http://www.lightstreamer.com/docs/client_web_jsdoc/PushPage.html#createEngine

rakeshxp

Thanks for the info. I will change to the new API.

Could you explain the difference between PushPage and Engine interms of error handling ? More specificly, do I need to add onClientAlert ( e.g ) on both PushPage and Engine? What are the scenarios when either of them is called ?

PS: I am already become a big fan of Lightstreamer! I couldn't find any page that tells me the pricing of the advanced version.
