我有一个 JSF 表单,上面有一个 selectBooleanCheckbox。如果复选框的值为真,我想在它旁边显示组合框。但不知何故,它不起作用。
这是我的代码:
<h:outputText value="Condition"/>
<h:selectBooleanCheckbox id="provisioningTargetCollector"
value="#{targetSource.provisioningTargetCollector}"
disabled="#{!sp:hasRight(facesContext, 'ManageApplication')}"
readonly="#{!sp:hasRight(facesContext, 'ManageApplication')}">
<f:ajax render="targetCollectorsGroup" />
</h:selectBooleanCheckbox>
<h:outputText value="Provisioning Target Collector"/>
<h:panelGroup id="targetCollectorsGroup">
<a4j:outputPanel id="targetCollectors">
<h:selectOneMenu id="collector"
value="#{targetSource.selectedTargetCollector}"
rendered="#{empty targetSource.object.id}"
disabled="#{!sp:hasRight(facesContext, 'ManageApplication')}"
readonly="#{!sp:hasRight(facesContext, 'ManageApplication')}">
<f:selectItem itemValue="" itemLabel="#{msgs.select_provisioning_target_collector}"/>
<f:selectItems value="#{targetSource.targetCollectors}"/>
</h:selectOneMenu>
<h:selectOneMenu id="fixedTargetCollector" value="#{empty targetSource.selectedTargetCollector ? 'None' : targetSource.selectedTargetCollector}"
rendered="#{not empty targetSource.object.id}"
disabled="true"
readonly="true">
<f:selectItem itemValue="#{empty targetSource.selectedTargetCollector ? 'None' : targetSource.selectedTargetCollector}"
itemLabel="#{empty targetSource.selectedTargetCollector ? msgs.none : targetSource.selectedTargetCollector}"/>
</h:selectOneMenu>
</a4j:outputPanel>
</h:panelGroup>
Bean 类方法:
private boolean _provisioningTargetCollector;
public boolean isProvisioningTargetCollector() {
return _provisioningTargetCollector;
}
public void setProvisioningTargetCollector(boolean provisioningTargetCollector) {
_provisioningTargetCollector = provisioningTargetCollector;
}
