Invoke rap application from another IFrame. [message #780534]

Hi,
I have a requirement to invoke certain operations on my RAP application from another application.
Say I have 2 applications App1 and App2 of which App2 is my RAP application. I'm making the 2 communicate using javascript. On click of a button in App1, App2 is loaded in a separate IFrame(Have achieved this). On click of another button in App1 some other operation needs to be performed in App2.
Here I want to create a rap request for that operation. This operation in my RAP application is performed by a button click, so I thought of simulating the button mouse event which would eventually create a request (Request.js does it).

Problems :
1. There are javascript functions to simulate events, but I dont have the ID for the button in RAP as its getting a new ID each time. How to work around this problem?
2. I want some parameters to be a part of the request that would be created as a result of this mouse event. Is there a way I can pass this?

Or is there another approach I should be looking at to achieve the above?

Javascript ref to create event :

var fireOnThis = document.getElementById('someID');
var evObj = document.createEvent('MouseEvents');
evObj.initMouseEvent( 'click', true, true, window, 1, 12, 345, 7, 220, false, false, true, false, 0, null );
fireOnThis.dispatchEvent(evObj);

Have you considered doing the communication indirectly via server? That
would be the straight-forward way to do this.

In RAP itself there are no functions to do this, and you should know
that browser-native functions are not guaranteed to work (the same) on
all browser. In any case, you might want to look at:

WidgetUtil.CUSTOM_WIDGET_ID
and
WidgetUtil.ENABLE_UI_TESTS

2. I want some parameters to be a part of the

You should not add anything to the request yourself, it would result for
client and server to be out-of-sync.

Greetings,
Tim

We need to add an unique ID for each of the UI components for our automation tests. You need a couple things:

1. Add "-Dorg.eclipse.rwt.enableUITests=true" in the VM argument for your run configuration.
2. Add code to attach an ID for the UI component. For example:

                Button button = new Button(group, SWT.PUSH | SWT.WRAP);
		button.setData(WidgetUtil.CUSTOM_WIDGET_ID, this.getClass().getName()
				+ "." + "pushbutton"); //$NON-NLS-1$ //$NON-NLS-2$
		button.setText("Push Button");

Thanks for your replies Tim,Ronald.

Tim, You mentioned about communicating via the server. Can you elaborate a li'l more on this or provide pointers.
Regarding the javascript, I know I'll have to consider browser dependency. But I wonder what's the alternative..

Hi.

I think the best way to achieve this is to send AJAX request from App1 to your special custom service handler on the server of App2. The service handler will call the function that you need to perform by clicking Button, etc. I guess Tim mentioned this approach.
