eXtremeComponents-1.0.1-RC2 关于limit 的一个…

版本：eXtremeComponents-1.0.1-RC2
环境：JSF

文件：departments.JSP
<f:vIEw>
<f:loadBundle var="text" basename="#{departmentList.bundleName}"/>
<h:form id="editDepartment">
<ec:table
items="departmentList.departments"
action="${pageContext.request.contextPath}/hr/departments.html"
imagePath="${pageContext.request.contextPath}/images/table/*.gif"
title="${text['userList.title']}"
rowsDisplayed="10"
form="editDepartment" var="department"
retrIEveRowsCallback="limit"
filterRowsCallback="limit"
sortRowsCallback="limit"
vIEw="limit"
autoIncludeParameters="false">
<ec:row highlightRow="true">
<ec:column title="${text['department.name']}" property="name"/>
</ec:row>
</ec:table>
</h:form>
</f:view>

文件：DepartmentList.Java
public List getDepartments() {
Context context = new HttpServletRequestContext(getRequest());
LimitFactory limitFactory = new TableLimitFactory(context);
Limit limit = new TableLimit(limitFactory);

//int pageSize = limit.getCurrentRowsDisplayed();
//可能是一个bug，生成 limit 的时候，并没有给 currentRowsDisplayed 赋值
int pageSize = limitFactory.getCurrentRowsDisplayed(0, 10);

FilterSet filter = limit.getFilterSet();

Page page = new PageHibernate(limit.getPage(), pageSize);
page.setFilters(FilterUtil.convert(filter));

page = departmentManager.getDepartments(page);

List list = page.getThisPageElements();

limit.setRowAttributes(page.getTotalNumberOfElements(), page.getPageSize());

getRequest().setAttribute("totalRows", new Integer(page.getTotalNumberOfElements()));

return list;
}

结果：
1.从limit中取不到pagesize，可能是一个bug，跟踪TableLimit原码，初始化的时候，并没有给 currentRowsDisplayed 赋值
2.没有显示“最后一页”，这个按钮
3.不能导出Excel文件，报错：
There is no export defined. This commonly happens if you do not declare the export (Export or ExportTag) before the row and columns.
