Hello,
i have a listShuttle with large lists (over 1000 entries), which causes very long loading times or in case of the internet explorer even to crash completely. So i decided to implement a paging-functionality to both lists and limit the entries displayed per page to 250.
I manipulated the getter for the lists like that.
public List<UserVO> getSourceList() { ArrayList<UserVO> allUsers = new ArrayList<UserVO>(); allUsers = getAllUsersWithoutTargetValues(); if (allUsers.size() > MAX_LIST_ENTRIES) { setSource_paging(true); setSource_max_pages(allUsers.size() / MAX_LIST_ENTRIES); int rest = allUsers.size() % MAX_LIST_ENTRIES; if (rest != 0) setSource_max_pages(this.source_max_pages + 1); if (currentPage != source_max_pages && rest != 0) { sourceList = allUsers.subList((currentPage - 1) * MAX_LIST_ENTRIES, currentPage * MAX_LIST_ENTRIES); } else { sourceList = allUsers.subList((currentPage - 1) * MAX_LIST_ENTRIES, (currentPage) * MAX_LIST_ENTRIES + rest); } } else { setSource_paging(false); sourceList = allUsers; } return sourceList; }
