------------------------------------
The change suggested in this issue is included in the patch that I attached to
DISPL-383.
> Table displays incorrectly when a non-PaginatedList is provided after it was
> previously displayed with a PaginatedList
> ----------------------------------------------------------------------------------------------------------------------
>
> Key: DISPL-327
> URL: http://jira.codehaus.org/browse/DISPL-327
> Project: DisplayTag
> Issue Type: Bug
> Components: Paging/Sorting
> Affects Versions: 1.1
> Reporter: Manuel Dominguez Sarmiento
> Priority: Minor
> Original Estimate: 30 minutes
> Remaining Estimate: 30 minutes
>
> In our application, sometimes we provide PaginatedList instances to
> DisplayTag, and sometimes we don't. So depending on the action, the same
> table might be displaying a PaginatedList or a simple List.
> To reproduce the problem, follow these steps in the same session:
> 1) Display table providing a simple List. It should work as expected.
> 2) Display the same table providing a PaginatedList. It should work as
> expected.
> 3) Display the same table providing a simple List. The results will NOT be
> what you expect. Rows from the previous step (2) will be visible.
> The problem seems to be that the reference to the PaginatedList is not
> released. The code that seems to be causing this is on TableTag.java, line
> 855.
> if (this.list instanceof PaginatedList)
> {
> this.paginatedList = (PaginatedList) this.list;
> this.list = this.paginatedList.getList();
> }
> When the list is NOT a PaginatedList, the reference is not released, and the
> sole presence of a reference is what triggers the unexpected behaviour. The
> fix I propose (tested and seems to work fine) is:
> if (this.list instanceof PaginatedList)
> {
> this.paginatedList = (PaginatedList) this.list;
> this.list = this.paginatedList.getList();
> } else {
> this.paginatedList = null;
> }
