org.apache.cocoon.forms.datatype
Class DynamicSelectionList

java.lang.Object
  org.apache.cocoon.forms.datatype.DynamicSelectionList

All Implemented Interfaces:

FilterableSelectionList, SelectionList

public class DynamicSelectionList
extends Object
implements FilterableSelectionList

SelectionList implementation that always reads its content from the source each time it is requested.

This list is filterable, and if a filter is provided, the "filter" parameter is appended to the URL, e.g. <fd:selection-list src="cocoon://pipeline.xml"/> will call, given the "foo" filter value, the URL cocoon://pipeline.xml?filter=foo.

Note: the class SelectionListBuilder also interprets the same fd:selection-list XML, so if anything changes here to how that XML is interpreted, it also needs to change over there and vice versa.
