Hi, all i need to integrate gwt with lightstreamer. I have some problems connected with how to call js in gwt. I have been using native methods before but this time something is going wrong and i can't understand what.
So here is every thing explained in brief: Lightstreamer has 2 .js lib files. I include them in my host page and they are loaded successfully. I wrote native method that calls some js code that subscribes for ls feeder: private static native void init(ListGrid grid, ListGridRecord record, int recordIndex) /*-{ try { var page = new PushPage(); page.context.setDomain("localhost"); page.onEngineCreation = function(engine) { engine.connection.setLSHost("localhost"); engine.connection.setLSPort(8888); engine.connection.setAdapterName("HELLOWORLD"); engine.changeStatus("STREAMING"); } page.bind(); page.createEngine("HelloWorldApp", "LS/", "SHARE_SESSION"); var schema = new Array("message","timestamp"); var group = new Array("greetings"); var nvt = new NonVisualTable(group,schema,"MERGE"); nvt.setSnapshotRequired(true); var c = 1; nvt.onItemUpdate = function(item, itemUpdate, itemName) { if (itemUpdate.isValueChanged("message")) { var msg = itemUpdate.getNewValue("message"); var ts = itemUpdate.getNewValue("timestamp"); if (c == 1) { alert(msg + " " + ts); c+= 1; } record.setAttribute("message", msg); record.setAttribute("timestamp", ts); grid.refreshRow(recordIndex); } } page.addTable(nvt,"hellotable"); } catch(error) { alert(error); } }-*/;' The same code executed in html page is working, but if i call it from onModuleLoad() the alert(error) shows me an error: PushPage is not defined and PushPage is defined in the external lightstreamer js lib files, which i included in my host page. Here is working code in html page: <html> <head> <script src="LS/lscommons.js" type="text/javascript"></script> <script src="LS/lspushpage.js" type="text/javascript"></script> </head> <body> <div source="lightstreamer" table="hellotable" item="greetings" field="message">loading...</div> <div source="lightstreamer" table="hellotable" item="greetings" field="timestamp">loading...</div> <div id="container"> Updates:<br/> </div> <script> var page = new PushPage(); page.context.setDomain("localhost"); page.onEngineCreation = function(engine) { engine.connection.setLSHost("localhost"); engine.connection.setLSPort(8888); engine.connection.setAdapterName("HELLOWORLD"); engine.changeStatus("STREAMING"); } page.bind(); page.createEngine("HelloWorldApp", "LS/", "SHARE_SESSION"); var schema = new Array("message","timestamp"); var group = new Array("greetings"); var nvt = new NonVisualTable(group,schema,"MERGE"); nvt.setSnapshotRequired(true); nvt.onItemUpdate = function(item, itemUpdate, itemName) { var updateText = "updating item " + itemName + ". "; if (itemUpdate.isValueChanged("message")) { updateText += "New value for last_price: " + itemUpdate.getNewValue ("message"); } document.getElementById("container").innerHTML += updateText + "<br/ >"; } page.addTable(nvt,"hellotable"); </script> </body> </html> In the gwt application i want to update some grid row and in the html application i update some div as you can see. So the main problem is why PushPage is not defined? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
