Hello. I am trying to do some pagination under Admin Panel for Groups. I made the appropriate changes to the code and i can see the pagination at the end of the page (When admin clicks on groups link under Admin Control Panel). The problem is that the groups page still shows all the groups in one page and shows the pagination at the bottom also which i am sure is not correct because i get a macro exception.
Can someone point me out what am i doing wrong. Thanks.
GroupAction
public void list()
{
System.out.println("Inside list()");
int start = this.preparePagination(DataAccessDriver.getInstance().newGroupDAO().getTotalGroups());
System.out.println("Start is [ " + start + " ] ");
int groupsPerPage = SystemGlobals.getIntValue(ConfigKeys.GROUPS_PER_PAGE);
System.out.println("Groups per page [ " + groupsPerPage + " ] ");
this.context.put("groups", new TreeGroup().getNodes());
this.context.put("grouping", DataAccessDriver.getInstance().newGroupDAO().selectAll(start ,groupsPerPage));
//this.commonData();
this.setTemplateName(TemplateKeys.GROUP_LIST);
}
private int preparePagination(int totalGroups)
{
int start = ViewCommon.getStartPage();
LOG.info("Start is [ " + start + " ]");
int groupsPerPage = SystemGlobals.getIntValue(ConfigKeys.GROUPS_PER_PAGE);
LOG.info("Groups Per Page is [ " + groupsPerPage + " ] ");
ViewCommon.contextToPagination(start, totalGroups, groupsPerPage);
return start;
