Hi all,
I am trying to do $Subject.
When the JavaScript method is in the <head> of html file itself I can
call the method from module load as a native method using JSN [1]I. But
when i refer to the js file from html page [2] and put the method in to
the js file i get the following gwt error[3]. Has anyone ever attempted
anything similar and achieved it successfully?
[1] in java class
public static native void gwtjsPlumbDemo() /*-{
$wnd.gwtjsplumbdemo();
}-*/;
[2] in gwtjsplumbdemo.js file
function gwtjsplumbdemo() {
alert("Success!!!");
}
in html
<script type="text/javascript" language="javascript"
src="gwtjsplumbdemo.js"></script>
[2] [115:32:19.737 [ERROR] [gwtjsplumb] Unable to load module entry point
