Direct Known Subclasses:

ERD2WEditableListTemplate

public class ERD2WEditableListPage
extends ERD2WListPage
implements ERXExceptionHolder, ERDObjectSaverInterface

List page for editing all items in the list. Name your page EditListYourEntityName. task will be edit, subTask will be list. See Component ERD2WEditableListTemplate for html/wod example. There is a "mass change" feature that can apply a change to all displayed objects. Think of it as an "input assistant". The changes are not saved when propagated, and the rows can be updated individually after a mass change has been applied. (Note: There is a ERDMassModifyButton class that may be more appropriate depending on your needs) To enable the mass change feature on an editable list page, do the following: 1/ Add a "showMassChange" rule that returns "true" for your edit list page 2/ If you want to restrict the keys that can be "mass edited", add a displayPropertyKeys rule with a restricted set of keys with the qualifer "(massChangeEntityDisplay = 1)" Known Issues: changing the number of items per batch causes problems (the display group's batch is updated too soon in the request/response loop)
