Exception during eventHandling in uix page

Question

Hello
My problem is the following:
when I use the tag <bc4j:findRootAppModule name="..."> in my eventHandling, if an exception occurs in the method called by the eventHandling, the exception is never thrown to the uix page and my errorpage is never called.
Here is the code of my eventHandling:
<handlers>
<bc4j:findRootAppModule name="WebCategArrayDescrViewAppModule" >
<method class="mypackage.LoginEvent" method="doLogin" />
</bc4j:findRootAppModule>
</handlers>
If the doLogin method throws an exception, nothing happens.
I would like to know where my exception is caught and how to retrieve it.
Thanks for your help
Virginie

Brent,
Apart from what the standard method is supposed to do, is the difference that getAttribute(String, boolean) with boolean="true" not only checks the session but also the request itself (that's where the boolean is for). The getRequestParameter() only checks the request. That is why getAttribute("Shipment", true) and getRequestParameter() both get the value, while getAttribute("Shipment") doesn't.
The request parameter is not automatically stored as a data object. You could do this using a custom action that retrieves the parameter using e.g. getRequestParameter(), create a UIX data object based on that and put that on the session. Than you can refer to it in a next page using getAttribute().
Having said this, I wonder if there is not a much simpler method to retrieve request parameters from the session. If I were you, I would post these same question on the JDeveloper forum to see if that is possible.
