[Seaside] Twitter Bootstrap Pagination issue

[Nick Ager]

I think you want to assign WAValueHolder to a temporary, something like:

| pageNumberHolder |
pageNumberHolder := WAValueHolder with: pageNumber.

html listItem
class: (self pageNumberActiveForPage: pageNumberHolder contents);
with: [ html anchor
callback: [ self goToPage: pageNumberHolder contents ];
with: pageNumber ]].
