It is working now.
But I have another issue with my apex class for pagination, it is only covered by 19%
public class ListPaginationBase { public Integer listSize {get; set;} public Integer pageSize {get; set;} public Integer currentPageIndex {get; set;} public List<Object> fullList {get; set;} public void initializePagination(Integer listTotalSize, Integer singlePageSize) { fullList = new List<Object>(); listSize = listTotalSize; pageSize = singlePageSize; currentPageIndex = 0; } public void initializePagination(List<Object> objectList, Integer singlePageSize) { fullList = ObjectList; listSize = fullList.size(); pageSize = singlePageSize; currentPageIndex = 0; } public Integer getPageCount() { //Returns the number of pages required to show all data given a page limit //if page limit is not set or is equal to zero, then return 1; dont divide by zero //is empty list then return 1 if (pageSize <= 0 || listSize <= 0) return 1; else return (Integer) Math.ceil((Decimal)listSize / (Decimal)pageSize); } public Boolean getHasNext() { //Returns true if the list has next pages return currentPageIndex < (getPageCount() - 1); } public Boolean getHasPrevious() { //Returns true if the list has previous pages return currentPageIndex > 0; } public Integer getfirstRowIndex() { //Returns the index of the first row to show in the PageBlockTable using the first attribute return currentPageIndex * pageSize; } public List<Object> getObjectPageList() { List<Object> returnList = new List<Object>(); for(Integer index = getFirstRowIndex(); index < getFirstRowIndex() + pageSize; index++) { if (index < fullList.size()) { returnList.add(fullList.get(index)); } } return returnList; } public PageReference firstAction() { //Action fired when the user click the First Button //Set the Page Index to Zero if(getHasPrevious()) currentPageIndex = 0; return null; } public PageReference lastAction() { //Action fired when the user click the Last Button //Set the Page Index to pages count - 1 if(getHasNext()) currentPageIndex = getPageCount() - 1; return null; } public PageReference nextAction() { //Action fired when the user click the Next Button //increment the current page index by 1 if(getHasNext()) currentPageIndex++; return null; } public PageReference previousAction() { //Action fired when the user click the Last Button //decrement the current page index by 1 if(getHasPrevious()) currentPageIndex--; return null; } }really appreciated
