Another circumstance this may happen is if the data is erased from the DB after you get a page, then you hit another page...
Right now, there is even an "if" for the "exceptional case" that the collection returned is empty (thus it would not even have a first page, you see?).
I think I should just set the current page to be the last page if it's more than the number of pages... And to be the first if it's negative... why not? Let's do kind of like google:
http://www.google.com/search?q=test&hl=en&lr=&ie=UTF-8&oe=UTF-8&start=10000000000000000000&sa=N
http://www.google.com/search?q=test&hl=en&lr=&ie=UTF-8&oe=UTF-8&start=-1&sa=N
I'll do it by tomorrow.

I'm using .8 version of the display tag with Tomcat 4.0.3 and everything works properly
Recently, I upgraded to Tomcat version 4.1.18 and have noticed that the paging functionality does not work properly. For example, I create a table that has 8 pages by selecting a valid date range in an HTML popup. Upon the initial display of the the table, Page 1 is shown. I then click on Page 6, which is displayed properly. Next I modify my date range so that the resulting table consists of only 2 pages. This crashes with the msg
"Invalid page (6) provided, value should be between 1 and 2'"
Digging around, it turns out that Tomcat 4.1.18 no longer calls the reset() method between calls and this effectively leaves the value "pageNumber" at 6 the next time a user hits the screen (the gory details about the Tomcat bug are at http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16001) This bug has been marked INVALID, so I don't think it will be fixed anytime soon.
Has anyone seen this problem and/or is there a fix for this? Seems like the thing to do is call the reset() method in the doStartTag() method, before the request object is obtained. Something like
columns = new ArrayList( 10 ); reset(); <------ add it here HttpServletRequest req = (HttpServletRequest)this.pageContext.getRequest();
Thoughts?
