FlowScope в приложении WebFlow/JSF2.2

Я пытаюсь обмануть JSF 2.1 в JSF 2.2 в приложении Spring WebFlow 2.4.2. Приложение сильно использует flowScope.FlowScope в приложении WebFlow/JSF2.2

Чтобы проверить, все ли работает, как и ожидалось, я клонировал https://github.com/spring-projects/spring-webflow-samples.git и изменил диапазон отелей с точки зренияScope to flowScope на сайтах бронирования/src/main/webapp/WEB-INF/flow/main/main-flow.xml :

<view-state id="reviewHotels"> 
    <var name="flowScope.hotels" class="org.springframework.webflow.samples.booking.HotelLazyDataModel"/> 
    <on-render> 
     <evaluate expression="flowScope.hotels.setSearchCriteria(searchCriteria)" /> 
    </on-render> 
    <transition on="select" to="reviewHotel"> 
     <set name="flowScope.hotel" value="flowScope.hotels.selected" /> 
    </transition> 
    <transition on="changeSearch" to="enterSearchCriteria" /> 
</view-state>

и reviewHotels.xhtml:

<p:dataTable id="hotels" var="h" value="#{hotels}" paginator="true" dynamic="true" 
      rows="#{hotels.pageSize}" page="#{hotels.currentPage}" lazy="true"> 
     ... 
     <p:column> 
      <f:facet name="header">Action</f:facet> 
      <p:commandButton id="viewHotelLink" value="View" action="select" icon="ui-icon-search"> 
       <f:setPropertyActionListener value="#{h}" target="#{hotels.selected}" /> 
      </p:commandButton> 
     </p:column> 
    </p:dataTable>

это привело к

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.webflow.execution.ActionExecutionException: Exception thrown executing [[email protected] targetAction = [[email protected] expression = flowScope.hotels.setSearchCriteria(searchCriteria), resultExpression = [null]], attributes = map[[empty]]] in state 'reviewHotels' of flow 'main' -- action execution attributes were 'map[[empty]]'

FlowScope был равен нулю.

Итак, вопрос в том, есть ли способ использования flowScope в приложении WebFlow/JSF2.2?

Из-за ошибки это выглядит как flowScope, но не null, но отели - null. Вы его настраиваете? –

Почему вы поместили var в состояние просмотра? Просто оставьте его на уровне потока, не получив его с помощью flowScope? –

Да, я вижу, спасибо! Но он все еще не работает, я обновлю вопрос. – user656449

Элемент <var/> может быть определен как на уровне потока, так и на уровне обзора. Это определяет, будет ли он помещен в область потока или область обзора.

В этом случае вы разместили его на уровне обзора, чтобы отели не попадали в область потока. Кроме того, вы не должны квалифицировать имя переменной с областью действия.

Знаете ли вы пример приложения webflow/jsf2.2, возможно, на github или что-то еще, в котором используется flowScope? – user656449

Образец, который вы упомянули, имеет JSF 2.2, если я не ошибаюсь. И в некоторых местах он использует область потока. Я не уверен, где у вас проблемы с этим. –

Правильно ли я понимаю, что это не сработало бы в JSF 2.1? Тогда _ «Я пытаюсь обжаловать JSF 2.1 в JSF 2.2» _ на самом деле неактуальен – Kukeltje
