About this sample
This sample shows how to set and retrieve a Public Render
Parameter (PRP). The parameter that's used is the pre-defined
"CUSTOM_CONTEXT" parameter defined by the WCM Rendering Portlet. The
top portlet shows a list of customer names that are defined in a JS
variable and used to populate a SELECT list. When the form is
submitted it sets the PRP value. The bottom portlet then retrieves
the PRP value and uses it to select the customer from the list. This
code retrieves the PRP.
