下拉多選編輯初始值加載賦值

<af:selectManyChoice value="#{DataProductBean.typeSelected}" label="使用範圍" id="smc1"
                                             contentStyle="width:170px;" autoSubmit="true"
                                             valueChangeListener="#{DataProductBean.typeChange}">
                            <f:selectItems value="#{bindings.TDictVO3.items}" id="si1"/>
                            <f:validator binding="#{bindings.TDictVO3.validator}"/>
                        </af:selectManyChoice>

java代碼，

private List<String> _typeSelected = new ArrayList<String>();

初始化方法加載賦值，先清空，在賦值

    public String choiceEdit(){
        _typeSelected.clear();
        DCIteratorBinding dataProductIterator = ADFUtils.findIterator("DataProductManageVOIterator");  
        Row rowData = dataProductIterator.getCurrentRow();
        String editType= rowData.getAttribute("Type").toString();
        
        String workType = (String) rowData.getAttribute("Productnetworktype");
        List<String> departments = new ArrayList<String>();
        if(workType!=null&&workType!="null"){
            String[] type = workType.split(","); 
            for(int i = 0 ; i < type.length ; i++){
                departments.add(type[i]);   
            }
        }
        _typeSelected = departments;
}

下拉change獲取值

    public void typeChange(ValueChangeEvent valueChangeEvent) {
        java.util.ArrayList al = (ArrayList) valueChangeEvent.getNewValue();
        if (al != null) {
            String typeResult = "";
            for(int i = 0 ; i < al.size() ; i ++){
                if( i == al.size() - 1){
                    typeResult = typeResult + al.get(i).toString();   
                }else{
                    typeResult = typeResult + al.get(i).toString() + ",";    
                }
            }

            this.setTypeValue(typeResult);
        }

    }
