Pedro Santos commented on WICKET-3377:
--------------------------------------
Hi Yaron, currently the page map is removed from session respecting the least
recently used sequence. Default page map can be removed from it and recreated
later when responding an request, I see no problem here.
> newPageMap at Session delete the default pageMap when excess Pagemap, and
> unneded pageMap are created for popupSettings with window name.

> Key: WICKET-3377
> URL: https://issues.apache.org/jira/browse/WICKET-3377
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4.15
> Reporter: Yaron
> Priority: Critical
>
> Related to: Session causing memory leak after WICKET-3108
> When excess Pagemaps are reached then it might delete the default page map.
> It seems unwise to delete the default page map as it usualy will live longer
> then page maps that will be created after it.
> Seting a window name for PopupSettings will set it a page map name, this will
> create a pageMap at link creation.
> It is not clear why the link target get the name using the pageMap (This
> create the page map) and not use the window name from the popup setting
> directly:
> Code from Link class:
> if (popupSettings != null)
> {
> IPageMap popupPageMap =
> popupSettings.getPageMap(this);
> if (popupPageMap != null &&
> popupPageMap.getName() != null)
> {
> tag.put("target",
> popupPageMap.getName());
> }
> }
> We have a table with links at the columns that each link needs a diffrent
> window name, the number of rows in the table changes and could reach 500.
> This now mean the page than containes the table with the link will lose its
> page map.
> It is needed to keep the default page map, and to create the page map for a
> popup link at link activation and not link creation.
