这是我的xhtml，其中包含一个数据表和一个带有不同<h:form>标签的对话框

                <p:column headerText="Action" styleClass="com-wdth-12">

            </p:dataTable>
        </h:form>
        <p:dialog id="dialog_answer" closable="true" header="Answer" visible="#{faqManagementBean.answerDialogBoxFlag}" rendered="#{faqManagementBean.answerDialogBoxFlag}" widgetVar="answerDialog" modal="true" styleClass="com-mr-lr15">
            <h:form id="form1">
                <div>

            </h:form>
        </p:dialog>
    </h:body>
</html>

，备用Bean的“保存”按钮代码为

public void saveAnswer() {
        if (!answerText.trim().isEmpty()) {
            FAQMemberMasterDao obj = new FAQMemberMasterDao();
            obj.setMemberName(answerText.trim());
            obj.setSetGroupId(102);
            obj.setMemberType(2);//2 is used for Answer
            obj.setCreatedUserId(Integer.valueOf(sessionBean.getUserID()));
            obj.setCreatedDateTime(new Date());
            obj.setLastModifiedUserId(Integer.valueOf(sessionBean.getUserID()));
            obj.setLastModifiedDateTime(new Date());
            obj.setSessionId(sessionBean.getSessionId());
            obj.setStatus(1);
            new QueryforHqlandSql().save(obj);
            mapOfQuestionsAnswers_IdAndText.put(obj.getMemberId(), answerText.trim());
            mapOfQuestionsAnswers_TextAndId.put(answerText.trim(), obj.getMemberId());
            saveQuestionAnswerMapping(toBeActionedQuestionId, obj.getMemberId());
            answerDialogBoxFlag = false;
            answerDialogShowSaveButtonFlag = false;
            answerDialogShowUpdateButtonFlag = false;
            fetchDataForQuestionsLookupList();
            new Validator().showMessageForSuccess("Saved Successfully");
        }
        questionTextForAnswerDialogLabel = "";
    }

和fetchDataForQuestionsLookupList();如下：

public void fetchDataForQuestionsLookupList() {
        System.out.println("fetchDataForQuestionsLookupList called");
        questiosLookupList.clear();
        String q = "from FAQMemberMasterDao where memberType=1 and status=1 order by memberId desc";
        List li = new QueryforHqlandSql().executeHQLQuery(q);
        if ((li != null) && (!li.isEmpty())) {
            for (int i = 0; i < li.size(); i++) {
                FAQMemberMasterDao obj = (FAQMemberMasterDao) li.get(i);;
                Object row[] = new Object[5];
                row[0] = obj.getMemberId();
                row[1] = obj.getMemberName();
                int temp = isAnswerExist(Integer.valueOf(row[0].toString()));
                if (temp == 0) {
                    row[2] = "Enter Answer";
                    row[3] = 0;
                    row[4] = "";
                } else {
                    row[2] = "View Answer";
                    row[3] = temp;
                    row[4] = mapOfQuestionsAnswers_IdAndText.get(temp);
                }
                questiosLookupList.add(row);
            }
        }
    }

单击“保存”按钮后，应关闭对话框（这将完全关闭），并且应使用对话框中<p:inputTextarea>中输入的答案来更新数据表。我已验证 questiosLookupList 中正在填充数据。唯一的问题是，单击对话框中的“保存”按钮时，它没有反映在数据表中。如果我通过在URL中按Enter手动重新加载页面，则数据表将得到更新。请帮助，因为我是JSF和primeface的新手。

无法从对话框中的commandButton更新Primefaces Datatable
