Hi

I have identified bug in petstore 3.2 example

Go to catalog component and opne Page.java in model. It is a value
object used for page wise navigation of catalog

Notice these two methods

public int getStartOfNextPage() { return start + objects.size(); }

public int getStartOfPreviousPage() {
return Math.max(start-objects.size(), 0);
}

here

objects : List of elements you want to display on page
getStartOfNextPage : will retrun record number of next page
getStartOfPreviousPage : record no of previous page

now lets consider, I will get 53 records from database and want to
display 5 records per page

so on the last page I will get 51-53 of 53. but if I click pervious page
link, I will get 48-50 of 53

because

51 - 3 = 48 and
53 - 3 = 50

which is bug. Actually it should display 45-50 of 53

pls look in to

regards,
Nishidhdha
