表不刷新

Question

我有一个由多行报告组成的表格。与复选框值更改事件相关的后台 bean 方法是获取行 ID 并使用该 ID 填充数组 (rowsToBeRemoved)。另一种方法获取此数组并从报告列表类中删除该对象：

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);
            }

代码执行良好，从报告列表中删除该对象，但之后我的表会显示一个混合报告列表。如果我刷新页面，它将按正确的顺序显示报告列表，否则不会。如果我尝试删除处于混合状态的行，它会删除报告，就好像它的顺序正确一样，从而以删除错误的报告结束。我希望我能解释一下..我做错了什么？

我认为这与您正在寻找的内容类似： 如何从支持 bean 刷新整个 JSF 页面

这不仅仅刷新页面的一部分，而是刷新整个页面。
