tasos zervos commented on DISPL-366:
------------------------------------
The code in org.displaytag.pagination.SmartListHelper.setCurrentPage(int
pageNumber) (line 240)
else if (pageNumber != 1 && pageNumber > this.pageCount)
{
// invalid page: set to last page
this.currentPage = this.pageCount;
}
sets this.currentPage=0 when the list has no data (this.pageCount==0).
Please update to something like:
else if (pageNumber != 1 && pageNumber > this.pageCount)
{
// invalid page: set to last page (unless last page equals 0!)
if (this.pageCount == 0)
{
this.currentPage = 1;
}
else
{
this.currentPage = this.pageCount;
}
}
This also covers DISPL-393.
