39 39  To receive values from the request (for instance, form data), implement the takeValuesFromRequest method. If your WODynamicElement responds to user actions, you must implement the invokeAction method. And if your WODynamicElement generates output, you must implement the appendToResponse method. At runtime, your WODynamicElement will be wired up to a WOComponent that you can access via the WOContext that is passed into each of the three methods above, which can be used to resolve bindings in a particular appearance on a page. For example, to retrieve the value of a binding, it might look like:

For instance, if your session had a ##public NSArray purchaseAmounts()## that returned an array of ##BigDecimal##s, you could refer to the binding ##value = session.purchaseAmounts.@sum##, which would return the sum of the values of the array. There are several other Array operations available in the Foundation classes, and Project Wonder provides even more in its [[ERXArrayUtilities>>WOnder-ERXArrayUtilities]] class.
