Jsf 表不刷新

我有一个由报告行组成的表。绑定到复选框值更改事件的backbean方法是获取行ID并用该ID填充数组（rowsToBeRemoved）。另一个方法获取此数组并从reportlist类中删除对象：

ObjectListDataProvider reportList = new ObjectListDataProvider();
List<RowKey> rowsToBeRemoved=new ArrayList();
Integer rowsToBeRemovedIndex = 0;

 for(RowKey rowToBeRemoved:rowsToBeRemoved){

            try {                
                System.out.println("rowToBeRemoved.toString()" + rowToBeRemoved.toString()); // outputs: rowToBeRemoved.toString()RowKey[0] 

                Report report = (Report) reportList.getObject(rowToBeRemoved);

                System.out.println("report.getId()" + report.getId()); //outputs: report.getId()199|


                Query resultQuery = queryGeneration(report.getId());
                List<String> dropTableQueries = resultQuery.getResultList(); // generated the queries to drop r tables


                for(int i=0; i<dropTableQueries.size(); i++){

                   String aDropTableQuery;
                   aDropTableQuery = dropTableQueries.get(i);
                    System.out.println("adroptableuery" + aDropTableQuery);// get single drop table query. outputs adroptableueryDROP TABLE r_199_0
                   entityManager.createNativeQuery(aDropTableQuery);
                    System.out.println("entitymanager dropTableQueries is invoked");//OK
                   reportList.removeObject(rowToBeRemoved);
                    System.out.println("removeObject");//OK
                    if (reportList.isRemoved(rowToBeRemoved)){
                        System.out.println("object removed");//OK
                    }                    
                    reportList.commitChanges();
                    System.out.println("commitchanges");//OK

               }
                reportJpaController.delete(report);
                reportList.removeRow(rowToBeRemoved);
                reportList.commitChanges();
                analyzerResultService.drop(report.getId().longValue());
                //rowsToBeRemoved.remove(rowsToBeRemovedIndex);
            } catch (Exception e) {
                error("Cannot delete report with row key " + rowToBeRemoved + e);
            }

ObjectListDataProviderReportList=新ObjectListDataProvider（）；
List rowsToBeRemoved=new ArrayList（）；
整数rowsToBeRemovedIndex=0；
对于（RowKey rowToBeRemoved:rowToBeRemoved）{
试试{
System.out.println（“rowToBeRemoved.toString（）”+rowToBeRemoved.toString（））；//输出：rowToBeRemoved.toString（）行键[0]
Report=（Report）reportList.getObject（rowToBeRemoved）；
System.out.println（“report.getId（）”+report.getId（））；//输出：report.getId（）199|
Query resultQuery=queryGeneration（report.getId（））；
List dropTableQueries=resultQuery.getResultList（）；//生成了用于删除r表的查询
对于（int i=0；i我认为这与您所寻找的类似：

这不仅刷新了页面的一部分，还刷新了整个页面。
你的意思是我应该实现Ajax4jsf吗？你的回答给了我线索。JSF中的表更新有问题。我没有实现Ajax，而是将onClick=“setTimeout（'#{user$recentreports.updateReportList（）}'，500}”我的表触发了backbean中已经定义的方法。它解决了我的问题。非常感谢。
