JSF Primefaces autoComplete建议列表

Question

<h:form>
                <h:panelGrid columns="2" style="margin-bottom:10px" cellpadding="5">
                    <h3>Search</h3>
                    <p:selectOneButton id="searchType" value="#{bean.searchType}">
                        <f:selectItem itemLabel="1" itemValue="1" />
                        <f:selectItem itemLabel="2" itemValue="2" />
                        <f:selectItem itemLabel="3" itemValue="3" />
                        <p:ajax event="change" update="search selected" />
                    </p:selectOneButton>

                    <p:autoComplete id="search" forceSelection="true" dropdown="true" value="#{bean.selectedSearch}" completeMethod="#{bean.search}">
                    </p:autoComplete>
                    <p:spacer />

                    <h:outputText value="Selected:" />
                    <h:outputText id="selected" value="#{bean.searchType}" style="font-weight: bold" />
                </h:panelGrid>
            </h:form>

我想根据按下 selectOneButton 来更改建议列表，但 autoComplete 仅显示加载页面时选择的建议列表。< / p>

bean completeMethod

private int searchType;
private ArrayList<String> auditoryNumberList;
private ArrayList<String> lectureNameList;
private ArrayList<String> groupNameList;
private String selectedSearch;
public ArrayList<String> search(String q) throws SQLException {
        switch (searchType) {
            case 1:
                if (groupNameList == null) {
                    groupNameList = model.getGroupNameList();
                    return model.search(groupNameList, q);
                } else {
                    return model.search(groupNameList, q);
                }
            case 2:
                if (lectureNameList == null) {
                    lectureNameList = model.getLectureNameList();
                    return model.search(lectureNameList, q);
                } else {
                    return model.search(lectureNameList, q);
                }
            case 3:
                if (auditoryNumberList == null) {
                    auditoryNumberList = model.getAuditoryNumberList();
                    return model.search(auditoryNumberList, q);
                } else {
                    return model.search(auditoryNumberList, q);
                }
            default:
                return null;
        }
    }
