选定的记录在primefaces dataTable liveScroll中无法正确显示

Question

我正在使用primefaces 5.2和jsf，在我的一个页面中有带有实时滚动的数据表。加载页面后，我显示了23条中的5条记录。最初在向下滚动之前，如果我选择第一条记录或第五条记录，则正确显示相应的选定记录。但是在使用liveScroll来获得第23条记录之后，如果我选择任何一条记录不起作用。（前5个工作） 我再一次从dataTable中选择前5条记录，显示第15条，第16条至第20条记录。

<div style="margin-top: 5px">

    <h:outputText id="headingdrafts" value="Plan: #{fcbean.pname}"

Managed Bean：

public DraftPlanBean（）{

    lazyPlanList = new DraftPlanView(getPlans(), draft);

}

模态：

protected int statusflag;

public DraftPlanView(List<PlanVO> datasource, int statusflag) {
    this.datasource = datasource;
    this.statusflag = statusflag;
}


public List<PlanVO> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String, Object> filters) {

    Map<String, String> filtersnew = ConUtil.convertFilters(filters);

    setFilterGlobal(filtersnew);

    String globalSortField = (String) SessionMgr.getSessionData("globalsortkey");

    return load1(first, pageSize, sortField, sortOrder, filtersnew,  globalSortField);
}

public void setFilterGlobal(Map<String, String> filters) {

    if (SessionMgr.getSessionData("globalfilterkey") != null) {

        if (!SessionMgr.getSessionData("globalfilterkey").equals("")) {

            String filterKey = (String) SessionMgr.getSessionData("globalfilterkey");

            String filterVal = (String) SessionMgr.getSessionData("globalfiltervalue");

            filters.put(filterKey, filterVal);
        }
        if (SessionMgr.getSessionData("globalfilterkey").equals("clearfilter")) {

            filters.clear();

        }

    }

}

public List<PlanVO> load1(int first, int pageSize, String sortField, SortOrder sortOrder,
        Map<String, String> filters, String globalSortField) {

    PlanProcess pprocess = PlanProcess.getPlanProcess();

    List<PlanVO> lst = null;

    try {

        lst = pprocess.getDraftedPlansList(first, pageSize, sortField, sortOrder, filters, SessionMgr.getProject(),
                statusflag, globalSortField);
        System.out.println("The list size is"+ lst.size());
        datasource.addAll(lst);
        if(lst.size()>0){
        this.setRowCount(pprocess.getPlansCount(filters, SessionMgr.getProject(), false, statusflag));
        }

    } catch (Exception ex) {
        ex.printStackTrace(); // temporary fix for exception handling
    }

    return lst;

}

}

我想从dataTable显示所选记录，我该怎么做？
