hi there, i have a page to edit an entity. this entity contains a list of childs connected via OneToMany. the page contains a component and that component (named ActionsLoop) contains an AjaxFormLoop component for edit/add/delete the child entities.
the ActionsLoop component has a parameter: @Parameter(required = true, defaultPrefix = BindingConstants.PROP) private List<CallOnDutyAction> actionsList; the actionsList elements wrapped into a map object (CollectionFactory.newConcurrentMap()) with an unique ID as map key. (AtomicLong ID_ALLOCATOR = new AtomicLong();) this is my onAddRow event method: Object onAddRow() { CallOnDutyAction action = new CallOnDutyAction(); action.setMapId(ID_ALLOCATOR.incrementAndGet()); actionsMap.put(action.getMapId(), action); return action; } and this is my onRemoveRow event method: void onRemoveRow(CallOnDutyAction item) { actionsMap.remove(item.getMapId()); } and here is my onAfterSubmit void onAfterSubmit() { for (CallOnDutyAction action : actionsMap.values()) { if (action.getId() == 0) actionsList.add(action); } } if i add a child entity, all is fine: after i submit the form, the new child added to child list and saved into the database table. but if i change or remove a child from the AjaxFormLoop nothing is happen with the modfied childs where is my fault ? -- with regards Sven Homburg http://www.chenillekit.org http://tapestry5-components.googlecode.com
