getting parameters from $CONTEXT

 $CONTEXT{parameters['dcr']}

So how far off am I? There is a dcr parameter in the querystring of the page.

I don't think you need ' in the bean path.

Well that link might have all the answers in it but I am not connecting the dots. I read that after the dev guide said "See the BeanUtils documentation of bean path, which is the parameter for this token". Sadly, nothing mentions "bean path" nor are any of the parameters listed that way. So after hours of flailing around I was hoping for a quick example of how to access a request parameter from the context token (why this is not one of the examples in the dev guide escapes me).

$CONTEXT{parameters(dcr)}

getParameters returns a Map and to access the map you use ()

From http://commons.apache.org/beanutils/api/org/apache/commons/beanutils/PropertyUtilsBean.html

For the purposes of this class, five formats for referencing a particular property value of a bean are defined, with the default layout of an identifying String in parentheses. However the notation for these formats and how they are resolved is now (since BeanUtils 1.8.0) controlled by the configured Resolver implementation:

Simple (name) - The specified name identifies an individual property of a particular JavaBean. The name of the actual getter or setter method to be used is determined using standard JavaBeans instrospection, so that (unless overridden by a BeanInfo class, a property named "xyz" will have a getter method named getXyz() or (for boolean properties only) isXyz(), and a setter method named setXyz().
Nested (name1.name2.name3) The first name element is used to select a property getter, as for simple references above. The object returned for this property is then consulted, using the same approach, for a property getter for a property named name2, and so on. The property value that is ultimately retrieved or modified is the one identified by the last name element.
Indexed (name[index]) - The underlying property value is assumed to be an array, or this JavaBean is assumed to have indexed property getter and setter methods. The appropriate (zero-relative) entry in the array is selected. List objects are now also supported for read/write. You simply need to define a getter that returns the List
Mapped (name(key)) - The JavaBean is assumed to have an property getter and setter methods with an additional attribute of type java.lang.String.
Combined (name1.name2[index].name3(key)) - Combining mapped, nested, and indexed references is also supported.

Thank you very much.
