Example 7 with BrowserFunction

/**
* Test that javascript can call java, java returns an Integer back to javascript.
*
* It's a bit tricky to tell if javascript actually received the correct value from java.
* Solution: make a second function/callback that is called with the value that javascript received from java.
*
* Logic:
* 1) Java registers function callCustomFunction() by setting html body.
* 2) which in turn calls JavascriptCallback, which returns value 42 back to javascript.
* 3) javascript then calls JavascriptCallback_javascriptReceivedJavaInt() and passes it value received from java.
* 4) Java validates that the correct value (42) was passed to javascript and was passed back to java.
*
* loosely based on Snippet307.
