problem when trying to call JavaMethod from Javascript using JSNI

[shraddha.bhatt]

Hi,

I am using smartgwt 2.5 PRO and smartclient 8.1
with GWT 2.4 Browser FF: 12.0

In my application I am creating a external HTML File to show a Map. Now I am setting this .HTML file in HTMLPane. I have a SAVE Button on HTML MapInfoWindow (using <INPUT>).

Now my requirement is when user clicks on the SAVE Button I need to get the lat/lng from the Map and pass these to my client side Java Method in order to geocode the address and set the values in the Window Fields.

I am using JSNI in order to call JavaMethod from my External HTML File onclick even of SAVE Button.

Map.HTML

<input type="button" value="Save" onclick="clickedSaveButton(ll.getLatitude(),ll.getLongitude())">

function clickedSaveButton(lat, lng) 
{
	getMyLatLng(lat, lng);
	alert(lat);
	map.dispose();
}

ClientSide Java File Presenter.java

public static native void exportCallToGetLatLng() 
/*-{
	$wnd.getMyLatLng = $entry(function(lat,lng)
  	{
  		alert('first '+lng);
		@in.systemintegration.client.presenter.LoadPresenter::callToGetLatLng(Ljava/lang/String;Ljava/lang/String;)(lat,lng);
	});	
}-*/;

public static void callToGetLatLng(String lat, String lng)
{
	String currentLat = lat;
	String currentLng = lng;
	SC.say("JAVA Variable Values :: "+currentLat+" ************* "+currentLng);
	callme(currentLat,currentLng);
}

public static void callme(String currentLat,String currentLng)
{
	SC.say("inside callme !! ");
	Criteria criteria = new Criteria();
	criteria.setAttribute("currentLat",currentLat);
		criteria.setAttribute("currentLng",currentLng);
		criteria.setAttribute("isLocationMap","true");
		DataSource loadDMI = DataSource.get(LOAD_DMI);
		loadDMI.fetchData(criteria, new DSCallback() 
	{
		@Override
		public void execute(DSResponse response, Object rawData, DSRequest request) 
		{
			String prop=response.getAttributeAsString("done");
			if(prop.equals("true"))
			{
				SC.say("Got a CallBackResponse From LOADSDAO !!! ");
			}
		}
	});
}

Now my JSNI Method works perfects returns me the correct lat/lng means I get the SC.say("inside callme !! ");. But after that the simple GWT code to send criteria on ServerSide does not get executed. I think it only allows JS code to run.

I dont know where I am wrong. Any Help will be greatly appreciated
