更改父属性时清除依赖属性值

Question

我有一个父属性OrganizationId和属性 - ProjectId，它依赖于OrganizationId。因此，在清除/更新时，应删除OrganizationId ProjectId。在清除OrganizationId的当前情况下，我们无法选择任何ProjectId，尽管现有的ProjectId值仍显示在页面上。

<af:inputComboboxListOfValues id="OrganizationCode"
    popupTitle="#{ResourcesGenBundle['Header.SearchandSelect.Searchandselectanobjectusingad']}: #{bindings.OrganizationCode.hints.label}"
    value="#{bindings.OrganizationCode.inputValue}"
    label="#{bindings.OrganizationCode.hints.label}"
    model="#{bindings.OrganizationCode.listOfValuesModel}"
    required="#{bindings.OrganizationCode.hints.mandatory}"
    columns="#{bindings.OrganizationCode.hints.displayWidth}"
    shortDesc="#{bindings.OrganizationCode.hints.tooltip}"
    searchDesc="#{bindings.OrganizationCode.hints.tooltip}"
    autoSubmit="true"
    partialTriggers="DeliveryName"
    valueChangeListener="#{CreatePickWaveBean.onOrganizationCodeChange}"
    binding="#{CreatePickWaveBean.organizationCode}">

<af:inputListOfValues id="projCostingProjectNumberId"
    popupTitle="#{ResourcesGenBundle['Header.SearchandSelect.Searchandselectanobjectusingad']}: #{bindings.ProjCostingProjectNumber.hints.label}"
    value="#{bindings.ProjCostingProjectNumber.inputValue}"
    label="#{wshpickreleaseuiBundle['ColAttr.ProjectCostingProjectNumber.ProjectPVO.ProjectCostingProjectNumber']}"
    model="#{bindings.ProjCostingProjectNumber.listOfValuesModel}"
    required="#{bindings.ProjCostingProjectNumber.hints.mandatory}"
    columns="#{bindings.ProjCostingProjectNumber.hints.displayWidth}"
    shortDesc="#{bindings.ProjCostingProjectNumber.hints.tooltip}"
    autoSubmit="true"
    binding="#{CreatePickWaveBean.pjcProjectNumber}"
    valueChangeListener="#{CreatePickWaveBean.onPjcNumberChange}">

public void onOrganizationCodeChange(ValueChangeEvent valueChangeEvent) {
    updateEVH(getOrganizationCode());

    private void updateEVH(EditableValueHolder evh) {
    if (evh != null)
        evh.setSubmittedValue(null);
}

尝试重置值或为inputListOfValues OrganizationId更改设置值null

您已经将projectId组件的绑定设置为“＃{CreatePickWaveBean.pjcProjectNumber}”因此您可以在ProjectId的值更改侦听器方法中使用以下代码

this.getPjcProjectNumber().setValue(null);

要么

this.getPjcProjectNumber().resetValue();
