here is my push code

HTML Code:

<html>

<head>
	<title>Hello World with Lightstreamer</title>
	<script language="JavaScript" src="LS/lscommons.js"></script>
	<script language="JavaScript" src="LS/lspushpage.js"></script>
</head>

<script>
	var page = new PushPage();
	page.context.setDomain("<?=$gsDomain?>"); // dominio.com
	page.onEngineCreation = function(engine) {
		engine.connection.setLSHost("<?=$gsLSHost?>"); // push.dominio.com
		engine.connection.setLSPort(<?=$gsLSPort?>);
		engine.connection.setAdapterName("ECONOTIFICATIONS");
		engine.changeStatus("STREAMING");
	}
	page.bind();
	page.createEngine("EcoNotificationsApp", "LS", "SHARE_SESSION");
	
	var group = ["<?=$sItemName?>"];
	var schema = ["message","timestamp"];
	var pushtable = new NonVisualTable(group, schema, "MERGE");
	pushtable.setCommandLogic(true);
	pushtable.setDataAdapter("EcoNotifications");
	pushtable.setSnapshotRequired(true);
	pushtable.onItemUpdate = function (itemPos, updateInfo, itemName) {
		var sMsg = updateInfo.getNewValue("message");
		var sDate = updateInfo.getNewValue("timestamp")
		if(sMsg!=null){
			var objDivAlarm = document.getElementById("divAlarm");
			objDivAlarm.innerHTML = sMsg + "<br>" + sDate;
		}
	};
	pushtable.onStart = function() {
		
	};
	
	/*var pushtable = new OverwriteTable(null, null, "MERGE");*/
	page.addTable(pushtable, "hellotable");
</script>

<body>

<div id="divAlarm">Empty...</div>

</body>
</html>

i think i identified the problem, i'm not sure if this is a bug or not.

the problem occurs when i put the "LS" folder (with JS libraries of Lightstreamer) into a "lib" folder. something like this:

Code:

myapp/
myapp/lib/LS/... --> here is the JS library
myapp/lsAlarms.php

in lsAlarms.php add the path in the src

HTML Code:

<script language="JavaScript" src="lib/LS/lscommons.js"></script>
<script language="JavaScript" src="lib/LS/lspushpage.js"></script>

when i move the "LS lib" to the same level to lsAlarms.php and lib, almost everything works fine (I'll open another post to see to solve another problem). something like this:

Code:

myapp/
myapp/lib/
myapp/LS/... --> here is the JS library
myapp/lsAlarms.php

in lsAlarms.php add the path in the src

HTML Code:

<script language="JavaScript" src="LS/lscommons.js"></script>
<script language="JavaScript" src="LS/lspushpage.js"></script>

i don't understand why this happends, maybe it's a bug. if you solve this, please let me know.

hi,

if you move the libraries you must update, besides the <script> tags, the createEngine call that needs to know where are the libraries located.
So you can put the LS folder under lib but your createEngine must look like this:
