NotSerializableException：org.springframework.binding.mapping.impl.DefaultMappingResults

Question

我正在

Caused by: org.springframework.webflow.execution.repository.snapshot.SnapshotCreationException: Could not serialize flow execution; make sure all objects stored in flow or flash scope are serializable

因此NotSerializableException完全占据了根本原因，因此无法弄清楚发生了什么。不可序列化的DefaultMappingResults来自

"lastError" -> "org.springframework.webflow.engine.FlowInputMappingException: Errors occurred during input mapping in state 'openAgreement' of flow 'menu'; errors = [[SourceAccessError@226a8851 mapping = flowScope.securityCards.selectedRow.agreementId -> agreementId, code = 'evaluationException', error = true, errorCause = org.springframework.binding.expression.EvaluationException: An ELException occurred getting the value for expression 'flowScope.securityCards.selectedRow.agreementId' on context [class org.springframework.webflow.engine.impl.RequestControlContextImpl], originalValue = [null], mappedValue = [null]]]"

不确定它是否相关但是在将JSF从2.1更新到2.2之后问题加剧但很可能在2.1下没有根错误

问题somehwat重新调整此one但不确定。

openAgreement状态：

<subflow-state id="openAgreement" subflow="menu">
    <on-entry>
        <evaluate expression="agreementService.init()" result="flowScope.agreementReadCriteria" />
    </on-entry>

    <input name="agreementReadCriteria" value="flowScope.agreementReadCriteria"/>

    <input name="agreementId" value="flowScope.securityCards.selectedRow.agreementId"/>
    <input name="currentBankId" value="flowScope.currentBankId"/>
    <input name="goToAgreement" value="true"/>

    <transition on="closeAgreement" to="securityCardsViewBasic">

    </transition>
</subflow-state>
