Helper.eventURL( , , ) in MAM CODE - What this function does ??

Question

Hi all,
Following are few code lines from MAM code :
// this is in common.inc"
<jsp:useBean id="helper"
    class="com.sap.mbs.core.web.ViewHelper" scope="request"/>
String allOrderURL = helper.eventURL("onOrderList", "orderListType", "ALL_ORDERS");
helper.getApplicationURL()
Could anyone please tell what this eventURL ,getApplicationURL methods are for ?
I couldnt find any documentation that explains it.
Regards,
Vipin

Hello Vipin.
Jo is rite.
The class is abstract but the class which is used to create the bean is the implementation class:
<b>DefaultViewHelper</b>
This is the implementation of the abstract class ViewHelper.
The ViewHelper is used to create URLs which are used to load a new page with our without submitting a form.
You can use eventURL to build an URL for a link you want to create (JO's example).
You can use submitEventURL in order to submit your form.
This method builds a call to a JavaScript method.
You can find this method in the file:
app-root/include/common.inc
function submitURL(url).
This function uses url as action for the submit.
So if you use something like this:
onClick="<%=helper.submitEventURL("onOK")%>"
all the form content is written to the context and the onOK method of the corresponding controller class is called. You can get the form content using the context in this controller method then.
When I started working with MAM I was also confused about the mbs.core Framework.
